CDynamicObjectArray Class Reference

Detailed Description

Dynamic array class for CSGObject pointers that creates an array that can be used like a list or an array.

It grows and shrinks dynamically, while elements can be accessed via index. It only stores CSGObject pointers, which ARE automagically SG_REF'd/deleted.
