# Primitive-Collections
|
||||
|
||||
Simple library to create primitive collections.
|
||||
Using template files to generate them.
|
||||
|
||||
Project for self teaching.
|
||||
# Primitive-Collections (To be Renamed)
|
||||
|
||||
This is a Simple Primitive Collections Library i started as a hobby Project.
|
||||
It's basis is of FastUtil and Java's Collection Library
|
||||
But both lib's have a lot of problems, and in FastUtils case foundation seem changes to be no longer possible.
|
||||
So this project was started.
|
||||
With a Rule-Sheet, and also hopefully more Test-Coverage.
|
||||
|
||||
Currently Cons against FastUtil (will/might change over time).
|
||||
- No Maps, this is next on the todolist.
|
||||
- No Singletons,
|
||||
- No BigLists/Sets/Maps
|
||||
- No Custom Spliterator support.
|
||||
- No Reference Collections.
|
||||
- Some implementations are slower due to not including all Micro-optimizations (this might not change)
|
||||
- Not as Specific Case Testing compared to FastUtil
|
||||
- No Java Serialization implemented
|
||||
- Code Generator is right now not finalized and no automatic setup exists as of this moment.
|
||||
|
||||
Pros against FastUtil
|
||||
- A Cleaner implementation of Collections that do exists: NavigableSet (Exists), PriorityQueues are Save-able outside of java Serialization and a lot of others.
|
||||
- More Consistency with features, not leaving a lot of holes in implementations. (Anything outside of HashMaps/Lists have massive holes)
|
||||
- Abstract Tests to allow more coverage on tests and allow quicker implementation on tests on new Implementations.
|
||||
- A lot better packaging where each types have their own packages to also make it easier to use the library. (lists/sets/collections/queues/utils)
|
||||
- Due to package name choice: This Library imports do not overshadow java imports. (Anything after s is overshadowed)
|
||||
- No Linux Environment necessary to generate the sourcecode if you want to work on it. All done with Java and or Gradle.
|
||||
- A lot of extra functions that become useful in some cases, like: ITrimmable, IArray, extractElements(from, to), moveToFirst/Last, PriorityQueue iterator. Better Synchronization wrappers that expose useful interfaces.
|
||||
- More Control how internals work thanks to SanityChecks
|
||||
- Support to some extend of a Java Specific Feature: Non-TypeSepcific Collection Non Delete functions. (any method that used Object as Parameter instead of Generic)
|
||||
|
||||
This Library also includes my own MergeSort Algorithm that does not need to duplicate the input array.
|
||||
It is a bit slower depending on the size, but is a stable sort that does not require to duplicate an array
