Class BufferPool

java.lang.Object

com.bonzaiengine.memory.BufferPool

public final class BufferPool
extends java.lang.Object

A non thread safe Buffer pool. It must be used only inside the OpenGL thread.

GC
wrap and useDoubleBuffer return a new allocate Buffer object sized approximately 64 bytes in the vm.
The buffer contents memory is shared with the BufferPool available memory,
so it's still a huge benefit than allocating the Buffer object and the raw memory block.
