All Implemented Interfaces:

LoaderIterator

Enclosing class:

LoaderBinary

private class LoaderBinary.LoaderIteratorBinary
extends Object
implements LoaderIterator

Loader iterator in charge of loading file data in small chunks. Usually data is divided in chunks small enough that can be directly loaded by graphical layers such as OpenGL (which has a limit of 65535 indices when using Vertex Buffer Objects, which increase graphical performance).
