Enclosing class:

BufferPool

public abstract static class BufferPool.BufferFactory
extends java.lang.Object

A BufferFactory is responsible for creating buffer and BufferPool.BufferContainer instances, and for returning the buffer Class. The Class returned by getBufferClass() may be a superclass or superinterface of the actual objects returned by newBuffer(int).
