+
+
+### Version 0.6.2
+- Added: Array only sorting function return the inputed array. This was done to allow for static final references to use the method in one go without having to make lambda wrappers. Cleaner code.
+- Added: Iterator Wrappers are now a bit more in Compliance with Java Standards.
+- Added: AsyncBuilders now Support Array Inputs to create cleaner code.
+- Changed: LinkedList.addBulk variable definition was triggering a false positive.
+- Fixed: TreeMap.subMap().entrySet().remove() wouldn't check primitives properly.
+- Fixed: SortedMap.sub/tail/headMap were looping into themselves.
+- Fixed: AbstractCollection.retainAll didn't push removed values through the consumer.
+- Fixed: AbstractCollection.toArray wouldn't reset the last entry if the input array was larger then the elements in the collection.
+- Fixed: SubList didn't check for ranges properly or didn't use parent list to validate changes.
+- Fixed: ArrayList.addElements didn't check input array fully and used the wrong variable to move the elements around.
+- Fixed: LinkedList.addElements(EmptyInput) would crash.
+- Fixed: LinkedList.swapRemove didn't account for if the removed element was the prelast one.
+- Fixed: LinkedList.removeElements would break the implementation if the list was almost empty and the middle element was removed.
+- Fixed: LinkedHashSet.addAndMoveToFirst wouldn't move elements to the first place.
+- Fixed: ArrayList/LinkedList extractElements crashing when 0 or less elements are desired.
+- Fixed: TreeMap pollFirst/LastKey should return the defaultMin/max value instead of a Empty value.
+- Fixed: TreeMap keySet implementation was missing the class type implementations to pass keySet tests.
+- Fixed: TreeMap.SubMap Iterator (primitive Keys) was crashing because a Null was set on to a primitive.
+
+
+### Version 0.6.1
+- Fixed: FIFO queue crashing when the last index is before the first index when peek is called.
+- Fixed: FIFO queue only clears the array if it was in use.
+- Added: Sorted Method for the stream replacing functions.
+
+### Version 0.6.0
+- Added: addOrGet for sets.
+- Added: Async API which allows to easily execute Iterables/Collections offthread without the complexity.
+- Added: CopyOnWriteArrayList and tests for it
+- Added: Support up to Java17.
+- Added: Build System now adds module-info if the Running JVM is 9 or higher
+- Added: ArrayList.of(Class, size) that allows you to allocate a size right at the creation of the List without having to create a wrapper array.
+- Added: A ConcurrentHashMap implementation.
+- Fixed: containsValue in the HashMap wouldn't check the nullKey
+- Removed: Deprecated functions from SortedMaps/Sets
+
+### Version 0.5.3
+- Added: OrderedMap/Set
+- Added: Deprecation to Functions that are specific to Ordered interfaces in the SortedMap/Set
+- Added: subFrom to Maps which is the counterpart of the addTo method
+- Added: pourAsList and pourAsSet (booleans excluded for sets) to Iterable
+- Fixed: ArrayList.grow had a small bug where it would trigger to early causing performance problems with exact sized collections.
+- Fixed: FIFOQueue size constructor had a small bug where it would trigger a array enlargement when all elements were inserted.
+
+### Version 0.5.2
+- Fixed: Bugs with Queues starting with the wrong size
+- Fixed: ArrayGrowth for Queues was +1 instead of +50%
+- Added: Benchmarks with java and FastUtil
+
+### Version 0.5.1
+- Fixed: Reworked the NavigableSet/Map implementations of RBTree/AVLTree/Array Sets/Maps so they are now deemed stable.
+- Added: Another 150k Unit tests.
+- Added: List and Set Unit tests for Integer (or Primitives in this case) to ensure basic stability there. (Now covering all sets and lists)
+- Fixed: Bugs with null values for primitive collections.
+- Removed: ArraySet/Map subSet/subMap implementation was removed.
+
+### Version 0.5.0
+- Added: 2 Helper functions to find out how many bits are required to store a Number.
+- Added: pour function directly into Iterable which allows to collect all elements in the Iterable directly.
+- Added: The new ToArray method from Java9 and newer into the library. Using a functional interface. (Just a backport)
+- Changed: Reworked how the Map Builder functions are created. They are now in a SubClass that moves them out of the way. Less Clutter. (This might break things if that was used before)
+- Added: Map Builder that allows now to Build Maps like Guava ImmutableMaps can be build. Note: This has a slight performance overhead.
+- Added: Unmodifiable and Synchronize wrapper functions direclty into Collection Interfaces. This is mostly a quality of life thing.
+- Added: Unmodifiable and Synchronized Wrapper Collections can now be cloned. They clone the underlying map which doesn't break functionality. (Had a usecase for it)
+- Added: A boxed putAll array variant.
+- Fixed: EnumMaps didn't keep track of their size and now got proper care and implementations as needed. There might be more work required but at least the core functionality is now up to date.
+- Added: Tests for the new Stream replace functions to ensure no bugs are left.
+- Fixed: Custom HashSet reduce function with a default value was checking incorrectly for present keys.
+- Added: Guava TestSuit
+- Fixed: HashCode and toString method would crash if the Object Key/Value was null
+- Added: AbstractTypeCollection now delegates the contains check to type-specific Collections if it detects it.
+- Fixed: Map.Entry toString wasn't writing values not like it should do.
+- Fixed: Set.hashCode now is the sum of the elements instead of a Unique HashCode based on the elements.
+- Fixed: Added missing NonNull Checks.
+- Fixed: Custom/OpenHashMap.containsValue implementation was wrong.
+- Fixed: Custom/OpenHashMap.compute/present/absent now works how it is specified in the Java Documentation
+- Fixed: Custom/OpenHashMap.merge/BulkMerge now works how it is specified in the Java Documentation
+- Fixed: Custom/Linked/OpenHashMap.keySet.remove was causing a infinite loop.
+- Fixed: Custom/Linked/OpenHashMap.entrySet.contains was not correctly comparing the entry.
+- Fixed: Custom/OpenHashMap.mapIterator now no longer crashes in certain cases.
+- Added: Custom/LinkedOpenHashMap now takes use of the improved Iterator it has for containsValue
+- Fixed: CustomOpenHashMap.keySet.forEach was basically putting out keys even if they were present
+- Fixed: ImmutableMaps issues thanks to the tests. Roughly the same as the rest of the maps
+- Fixed: RB/AVLTreeMaps issues. Roughly the same as the rest of the maps
+- Fixed: SubLists are now properly implemented.
+- Fixed: HashSet Iterator bugs now fixed... That was Painful.
+- Added: Tests for Lists and Sets
+
+### Version 0.4.5
+- Added: removeAll/retainAll(Collection c, Consumer r) which receives all the elements that got deleted from the collection
+- Fixed: Supplier get function wasn't referencing original function.
+- Added: addIfPresent/Absent to lists
+- Added: distinct, limit and peek iterators
+- Added: Iterable's can now reduce its contents
+- Added: Better ForEach support for IterableWrappers so a Iterator chain is not created
+- Added: SwapRemove to Lists which moves the last element into the desired space to be deleted
+- Added: More Test cases
+

 # Primitive-Collections
+This is a Simple Primitive Collections Library aimed to outperform Java's Collection Library and FastUtil.  
+Both in Performance and Quality of Life Features.  
 
-This is a Simple Primitive Collections Library i started as a hobby Project.     
+## Benchmarks
-It is based on Java's Collection Library and FastUtil.     
+Benchmarks can be found here: [[Charts]](https://github.com/Speiger/Primitive-Collections-Benchmarks/blob/master/BENCHMARKS-CHARTS.md), [[Tables]](https://github.com/Speiger/Primitive-Collections-Benchmarks/blob/master/BENCHMARKS.md)
-But its focus is a different one.     
+
+## Special Features
+[Here](features.md) you find a set of features added to Primitive Collections.   
+These are designed to improve performance or to provide Quality of Life.  
 
 ## Main Features:      
-- ArrayLists / LinkedLists
+- ArrayLists / LinkedLists / CopyOnWriteLists
-- HashSet/Map (Linked & HashControl)
+- HashSets/Maps (Linked & HashControl)
-- TreeSet/Map (RB & AVL)
+- TreeSets/Maps (RB & AVL)
-- EnumMap
+- EnumMaps
 - Immutable Maps/Lists/Sets
-- Priority Queue
+- ConcurrentHashMaps
-- Streams
+- Priority Queues
-- SplitIterators
+- Streams & Functional Queries
-- Iterators
+- Split/Iterators
 - Pairs
 - Unary/Functions
 - Suppliers
 - Bi/Consumers
-
+- AsyncBuilders  
-## Specialized Functions
-New Specialized functions that were added to increase performance or reduce allocations or Quality Of life.
-To highlight things that may be wanted.
-- Iterable:
-	- map/flatMap/arrayFlatMap: A Light weight version of Stream.map().
-	- findFirst: Allows to find the first element of a Predicated Iterable.
-	- filter: Allows to filter unwanted elements for wrapped Iterable
-	- matchAny/matchNone/matchAll: Allows to find elements in a collection.
-	- count: counts all valid elements in a collection.
-	- forEach: Allows to input a second element into a forEach move allowing for more flexibility for Method References
-- Collection:
-	- containsAny: Allows to test if another collection contains an of the elements of the tested collection.
-	- primitiveStream: Provides access to the closest Java Stream Type.
-	- copy: shallowCopies the collection, used instead of clone because this is better to use.
-		(subCollections/synchronized/unmodifiable not supported for obvious reasons)
-- List:
-	- add/get/removeElements (From FastUtil): Allows to add/get/remove an Array into/from a list. Just with less overhead
-	- extractElements: Allows to remove a Range of elements from the List and get what was removed.
-	- Unstable Sort(From FastUtil): Uses a faster but not stable sort (Quick-Sort as example) to sort the list.
-- SortedSet:
-	- addAndMoveToFirst/Last (From FastUtil but moved to Interface): Allows to add a element to the first/last position of a sorted set.
-	- moveToFirst/Last: Moves the desired element at the first/last position of the SortedSet.
-	- pollFirst/Last: Allows to poll the first/last element of the set.
-- Map:
-	- putAll: putAll but in Array form.
-	- putAllIfAbsent: Puts only the elements that are absent.
-	- addTo (Only Primitives Values) (From FastUtil but moved to Interface): allows to add to the value of a given key. If not present it will be added. (Accumulator)
-	- addToAll: Same as addTo but bulkVersion.
-	- removeOrDefault: removes a Element and if not present returns the default value instead of the present value.
-	- mergeAll: BulkVersion of Merge function.
-	- supplyIfAbsent: A Supplier based computeIfAbsent
-- Sorted Map:
-	- addAndMoveToFirst/Last (From FastUtil but moved to Interface): Allows to add a element to the first/last position of a sorted Map.
-	- moveToFirst/Last: Moves the desired element at the first/last position of the Map.
-	- getAndMoveToFirst/Last: gets the element and moves it to the first/last position. Replicating a Optional LinkedHashMap feature.
-	- pollFirst/LastKey: Allows to poll the first/last element.
-	- first/LastValue: Allows to get the first/last value from the Map.
-	
 
 # Notes about Versions
 Any 0.x.0 version (Minor) can be reason for massive changes including API.     
 To ensure that problems can be dealt with even if it is breaking the current API.     
-Any breaking changes will be Documented (once 1.0 is released)     
 
 # How to install

+## Quality Of Life Features
+New Specialized functions/classes that were added to increase performance and/or reduce allocations and/or for Quality of life.  
+
+
+# Functions
+
+Functions that increase performance or are quality of life in their nature.   
+
+<details>
+<summary>Iterable</summary>
+<p>
+
+## Functional Functions
+
+Java adds themselves a lot of functional functions like,  
+- Stream:
+	- Map/FlatMap
+	- Filter/Distinct/Limit/Sorted
+	- Count/FindFirst/Collect
+	- Peek/ForEach/Reduce
+	- anyMatch/allMatch/NoneMatch   
+
+that allows to process a collection in a functional way.   
+But these require streams which have a lot of Overhead in their nature.    
+
+Luckly Primitive Collections adds replacement functions that provide the same functionality but with minimal overhead.   
+Here are some examples:
+```java
+public ObjectIterable<Path> toPath(ObjectIterable<String> iterable) {
+	return iterable.map(Paths::get).filter(Files::exist);
+}
+
+public Iterable<Path> toPath(Iterable<String> iterable) {
+	return ObjectIterables.map(iterable, Paths::get).filter(Files::exist);
+}
+
+public int sum(IntIterable iterable) {
+	return iterable.reduce(Integer::sum);
+}
+```
+
+## AsyncAPI</summary>
+
+The AsyncAPI is a Feature that simplifies the processing of Collections on a separate thread.   
+It uses the same concept as Javas Stream API but uses the light weight Functions from Primitive Collections to achieve the same thing.   
+Unlike Javas StreamAPI the AsyncAPI is always singleThreaded and more like Javas CompletableFuture, which you can await or let run Asynchronous.    
+
+The Goal is it to simplify the processing of Collections asynchronous.   
+Especially on tasks which don't have to be finished instantly but can be processed on the side.   
+
+Here is a example of how the API works.
+```java
+public void processFiles(ObjectCollection<String> potentialFiles) {
+     potentialFiles.asAsync()
+         .map(Paths::get).filter(Files::exists) //Modifies the collection (Optional)
+         .forEach(Files::delete) //Creates the action (Required)
+         .callback(T -> {}} //Callback on completion, still offthread (Optional)
+         .execute() //Starts the task. (Required)
+}
+```
+</p>
+</details>
+<details>
+<summary>Collection</summary>
+<p>
+
+These are functions specific to the Collections interface, stuff that everyone wished it was present to be in the first place.
+
+## AddAll (Array)
+Adding Elements to a Collection usually requires either a for loop or a Arrays.wrap().   
+This isn't an issue with Primitive Collections.
+```java
+public void addMonths(ObjectCollection<String> months) {
+	months.addAll("January", "February", "March", "April", "May", "June", "July", "August", "September, "October", November", "December");
+}
+
+public void addElements(ObjectCollection<String> result, String[] elements) {
+	result.addAll(elements, 0, 5); //elements, offset, length
+}
+```
+
+## containsAny
+Everyone hates comparing if 2 collections have part of each other included.   
+The solution usually requires for loops and keeping track if things were found or not.   
+And every Java Developer had this issue at least once and wished for a clean solution.
+```java
+public boolean hasMonths(ObjectCollection<Month> target, Collection<Month> toFind) {
+	return target.containsAny(toFind);
+}
+```

+## Copy
+Collections get copied every now and then. There is only 2 ways that this happens.  
+Javas Clone API or using Constructor that supports collections.  
+Javas Clone API is kinda in a Zombie state, where it is supported or not. Its not really clear if you should use it or not.  
+The Clone CloneNotSupportedException isn't helping either, causing more janky code.  
+While a Constructor can only support so much and testing for every case isn't really viable.  
+
+So the decision was made to straight out not support clone and instead add a copy function which doesn't use a checked exception.  
+It works exactly like the clone function. In a sense where it creates a shallow copy. (SubCollections do not work for obvious reasons)
+```java
+public IntCollection copy(IntCollection original) {
+	return original.copy();
+}
+```
+
+## Primitive Streams
+Since Javas Stream API is still really useful, even at its shortcomings, Primitive Collections provides easy access to it.  
+Generic Streams and the closest Primitive Stream will be provided. So a FloatCollection goes to a DoubleStream.
+```java
+public IntStream createStream(IntCollection source) {
+	return source.primitiveStream();
+}
+```
+
+## RemoveAll/RetainAll with listener
+Ever wanted use removeAll or retainAll and wanted to know what elements actually got deleted?  
+The usual solution is to create a copy and then apply it to the original and cross reference them.  
+Which leads to really messy code and just hasn't a clean solution.  
+Luckly Primitive Collections got you covered.
+```java
+public void removeInvalidFiles(ObjectCollections<Path> files, ObjectCollection<Path> toRemove) {
+	files.removeAll(toRemove, T -> System.out.println(T));
+}
+
+public void removeInvalidFiles(ObjectCollections<Path> files, ObjectCollection<Path> toKeep) {
+	files.retainFiles(toKeep, T -> System.out.println(T));
+}
+```
+
+## ToArray 
+Primitive Collections supports primitive/generic toArray functions for its Primitive Collections.  
+On top of that the Object side gets a Java9 function ported back to java8, which uses a functional Interface to create the backing array.
+```java
+public Integer[] toArray(IntCollection c) {
+	return c.toArray(new Integer[c.size]);
+}
+
+public int[] toArray(IntCollection c) {
+	return c.toIntArray();
+}
+
+public String[] toArray(ObjectCollection<String> c) {
+	return c.toArray(String::new);
+}
+```
+</p>
+</details>
+
+<details>
+<summary>List</summary>
+<p>
+
+These functions are List specific functions, a couple of these are from FastUtil.
+
+## add/get/remove/extractElements
+These functions really useful helper functions. 3 of which are copied from FastUtil. (extract is from Primitive Collections)  
+They are basically array forms of addAll, getAll, removeRange and removeAndGetRange. This is the simplest way to describe it.  
+
+Here some example:
+```java
+public void addAll(DoubleList list) {
+	list.addElements(0D, 12.2D, 3.5D, 4.2D);
+}
+
+public double[] getAll(DoubleList list, int amount) {
+	double[] result = new double[amount];
+	list.getElements(0, result);
+	return result;
+}
+
+public void removeRange(FloatList list) {
+	list.removeElements(5, 14);
+}
+
+public float[] extractRange(FloatList list) {
+	return list.extractElements(5, 14); //Returns the removed elements
+}
+```
+
+## addIfPresent/addIfAbsent
+These two functions are simple helper functions that check internally if a element is present or absent before adding them to the List.   
+Removing the need for a contains or indexOf check every time you want to add a element.
+While it is of course better to use a set, there is cases where this is still useful.
+
+```java
+public void addElements(IntList list, int... numbersToAdd) {
+	for(int e : numbersToAdd) {
+		list.addIfAbsent(e);
+	}
+}
+
+public void addExisting(ObjectList<String> list, String... textToAdd) {
+	for(String s : textToAdd) {
+		list.addIfPresent(s);
+	}
+}
+```
+
+## SwapRemove
+Lists when removing a Element shift usually the backing array to the left based to shrink the elements.  
+While that isn't computational expensive with LinkedLists, it is with ArrayLists.  
+Here comes swapRemove into play, which just removes the desired elements and instead of shifting left puts the last element in its place.
+This reduces the data copying required down to 1 element instead of an array.
+
+```java
+public int remove(IntList elements, int indexToRemove) {
+	return elements.swapRemove(indexToRemove);
+}
+```
+
+## Unstable Sort (From FastUtil)
+Unstable Sort uses a Faster but not as stable sorting algorithm to sort the Collection.  
+Stable doesn't mean crashing, but more like that the result isn't exactly perfectly sorted.  
+```java
+public void sort(List<Month> list, Comparator<Month> sorter) {
+	list.unstableSort(sorter);
+}
+```
+</p>
+</details>
+
+<details>
+<summary>Map</summary>
+<p>
+
+These functions are based on the Map interface. Useful functions you really would want.  
+
+## addTo/subFrom
+addTo (from FastUtil) and subFrom are mathematically functions that either add or subtract from the value of a given key.   
+And if the key isn't present or would result in the default value it will either add or remove the entry from the Map. Given the circumstance.   
+This is a really useful function and I wish FastUtil made it accessible by default but sadly it isn't.   
+To simplify the explanation:    
+- addTo if no element is present puts in the desired number, otherwise it sums up the two values.   
+- subFrom if a element is present subtracts from it, if the element reaches the default value it removes the element from the map. If not present it will be ignored.   
+```java
+public void addTo(Object2DoubleMap<Month> map, Month key, double averageTrainsRepaired) {
+	map.addTo(key, averageTrainsRepaired);
+}
+
+public void subFrom(Long2IntMap map, long key, double amount) {
+	map.subFrom(key, amount);
+}
+```
+
+## addToAll
+Simple bulk version of the addTo function since sometimes you want to merge 2 maps for summing.  
+Especially if your work is multi-threaded this can become useful.
+
+```java
+public void addTo(Object2DoubleMap<Month> map, Object2DoubleMap<Month> trainsRepaired) {
+	map.addToAll(trainsRepaired);
+}
+```
+
+## mergeAll
+This is a simple bulk version of merge since merging 2 maps is more frequent then people might think and leads to cleaner code too.
+```java
+public void merge(Long2ByteMap result, Long2ByteMap toMerge) {
+	result.mergeAll(toMerge);
+}
+```
+
+## putAll (Array)
+This allows to put keys and values as arrays instead of requiring a WrapperMap to insert the elements.  
+Not as useful as the Collections.addAll variant but still really useful.
+```java
+public void putAll(Int2DoubleMap map, int[] keys, double[] values) {
+	map.put(keys, values, 2, 15);
+}
+```
+
+## putAllIfAbsent
+putAll has this usual quirk where if a element is present it will replace the value, and sometimes this is not wanted.  
+While putIfAbsent exists it has no real mass form and makes iterative solutions really uneasy to use.  
+Here comes the helper function that gets rid of that problem.
+```java
+public void merge(Long2ObjectMap<String> regionFiles, Long2ObjectMap<String> toAdd) {
+	regionFiles.putAllIfAbsent(toAdd);
+}
+```
+
+## removeOrDefault
+getOrDefault is a really useful function that find use cases all the time.   
+Sadly by default there is no variant of removeOrDefault, while it has less cases still could be used every now and then.  
+This function basically tries to remove a element, if it is not present it will just return your desired default.
+```java
+public Path removeCache(Long2ObjectMap<Path> caches, long key) {
+	return caches.removeOrDefault(key, Paths.get("nuclearFun"));
+}
+```
+
+## supplyIfAbsent
+This one is one of my favorites. computeIfAbsent is a really useful function.   
+But in 90% of the cases I use it the value is a collection.  
+This becomes really annoying since methodReferences are faster/cleaner then Lambdas in my opinion.  
+supplyIfAbsent is basically computeIfAbsent but without a key, perfect for the default constructor of a collection.  
+This is the whole reason it exists.  
+```java
+public void example(Int2ObjectMap<List<String>> map, Int2ObjectMap<String> toAdd) {
+	for(Entry<String> entry : toAdd.entrySet()) {
+		map.supplyIfAbsent(entry.getKey(), ObjectArrayList::new).add(entry.getValue());
+	}
+}
+```

+# Interfaces
+
+Interfaces that provide essential or quality of life features.
+
+<details>
+<summary>ITrimmable</summary>
+<p>
+
+The ITrimmable is Accessor interface that allows you to access a couple helper functions to control the size of your collections.  
+This was created for the constant casting requirement to implementations just to shrink collections which get annoying over time.  
+
+## trim
+This function basically trims down the backing implementation to use as little memory as required to store the elements in the collection.  
+Optionally a desired minimum size can be provided as of how low it should go at worst.  
+
+## clearAndTrim
+when you want to reset a Collection completely you have 2 options. Clear it and then call trim, or recreate the collection.  
+clearAndTrim solves this problem by clearing the collection and trimming it in one go, reducing overhead to achieve such a thing.  
+
+</p>
+</details>
+
+<details>
+<summary>IArray</summary>
+<p>
+
+IArray is a Accessor interface that provides more access to collections by providing tools to grow your collection as needed.  
+While putAll/addAll try to ensure that you have enough room for your elements, this is not really a solution for all cases.  
+Sometimes you need to ensure the Collection is pre-initialized.  
+IArray grants you that control.  
+
+There is also a type specific that provides you access to the backing array implementation of Lists for faster Iteration but that is a really specific case.  
+
+## ensureCapacity
+Ensures that your collection has enough storage for the elements you want to insert.  
+
+## elements (ITypeSpecificArray)
+Allows you access to the backing array of a List which is for people who know what they are doing.  
+There is a lambda version of this function too which makes sure for synchronizedLists that you are the only one accessing the array.  
+
+</p>

+
+<details>
+<summary>OrderedMap</summary>
+<p>
+
+The OrderedMap is a real edge case interface that was born for a need.    
+FastUtil added functions that were like moveToFirst which were hardcoded to the implementation.  
+They didn't fit into something like a SortedMap because the Set wasn't sorted.  
+So OrderedMap was born, which isn't random but ordered in a specific way that can be changed.  
+
+## getAndMoveToFirst/getAndMoveToLast
+Returns a desired element and removing it to the first/last spot in the Map. Moving the element that was at its spot after/before it.  
+
+## moveToFirst/moveToLast
+Moves the element if present to the first/last spot in the Map. Moving the element that was at its spot after/before it.  
+Returns true if the element was actually moved.  
+
+## putAndMoveToFirst/putAndMoveToLast
+Adds the desired element and moves it to first/last spot in the Map. Moving the element that was at its spot after/before it.  
+
+## firstKey/lastKey (Optional poll)
+Provides access to the current first/last key of the Map.  
+Optionally can be polled if desired.  
+
+## firstValue/lastValue
+Provides access to the current first/last value of the Map.  
+
+</p>

+<summary>OrderedSet</summary>
+<p>
+
+The OrderedSet is a real edge case interface that was born for a need.    
+FastUtil added functions that were like moveToFirst which were hardcoded to the implementation.  
+They didn't fit into something like a SortedSet because the Set wasn't sorted.  
+So OrderedSet was born, which isn't random but ordered in a specific way that can be changed.  
+
+## addAndMoveToFirst/addAndMoveToLast
+Adds the desired element and moves it to first/last spot in the Collection. Moving the element that was at its spot after/before it.  
+
+## moveToFirst/moveToLast
+Moves the element if present to the first/last spot in the Collection. Moving the element that was at its spot after/before it.  
+Returns true if the element was actually moved.  
+
+## first/last (Optional poll)
+Provides access to the current first/last element of the set.  
+Optionally can be polled if desired.

+/**
+ * 
+ * 
+ * The Async API allows you to process collections on a different thread without having to deal with the Multithreading complexity. <br> 
+ * It uses the Lightweight Stream Replace API to do its work, which can make it faster then sequential streams. <br>
+ * This feature isn't designed to do Multithreading work, but to allow moving work off the main thread into a worker thread. <br>
+ * So anything executed on this is still Singlethreaded. <br>
+ * <br>
+ * How it works is you create the AsyncBuilder using a Iterable of the Type. <br>
+ * Then select things you want to use on the Iterable. <br>
+ * - For example: map/filter/peek/limit/etc <br>
+ * <br>
+ * After that you select your action the Iterable should be applied on. <br>
+ * - For Example: forEach/findFirst/matchAny/etc <br>
+ * <br>
+ * Then optionally a custom Executor or callback can be applied <br>
+ * At the end either execute or join can be called to start the task. <br>
+ * - execute will return the Task reference so that the task can be traced back. <br>
+ * - join will await the completion of the task and return the return value <br>
+ * <br>
+ * During Construction a couple Disposable Builder Objects will be created. <br>
+ * These will be only used during construction. <br>
+ * <br>
+ * The Task Object is also pause-able/Interruptable at any moment during the Processing. <br>
+ * 
+ * A small example
+ * <pre><code>
+ * public void processFiles(ObjectCollection&#60;String&#62; potentialFiles) {
+ * 	potentialFiles.asAsync()
+ * 		.map(Paths::get).filter(Files::exists) //Modifies the collection (Optional)
+ * 		.forEach(Files::delete) //Creates the action (Required)
+ * 		.onCompletion(T -&#62; {}} //Callback on completion (Optional)
+ * 		.execute() //Starts the task. (Required)
