A Haxe library containing data structures for games.

Data Structures For Games

ds logo

The library contains parametrized classes that allow programmers to easily implement standard data structures like linked lists, queues, stacks or multi-dimensional arrays. The result is somewhere in between the C++ STL (Standard Template Library) and the Java Collection framework.

Documentation

Cross-Platform Support

ds supports the following Haxe compilation targets: -swf, -js, -neko, -python, -php, -cpp

-hl, -java, -cs, jvm are experimental.

Installation

Install Haxe and run $ haxelib install polygonal-ds from the console, then compile with $ haxe ... -lib polygonal-ds.

Conditional Compilation Flags

-D generic

Enables generic classes (adds @:generic meta). Nice performance boost for static typed platforms (-swf,-cpp only).

-D alchemy

Enables fast virtual memory for FP10+ ("alchemy memory"). Extra performance for Flash.
