All Implemented Interfaces:

Target

public class ByteBufferPool
extends BufferPool<java.nio.ByteBuffer>

This class implements a self cleaning pool of ByteBuffers, each wrapped around a byte array of the configured buffer length. Superclass get() and release(ByteBuffer) methods can be used to allocate and release ByteBuffers from the pool. ByteBuffers are allocated on demand, and released to the garbage collector after 10 minutes without use, unless the superclass setIdleTimeoutSeconds method is called to change the timeout. If there is a leak and release is not called to return a ByteBuffer after use, it will still be released from the pool after 10 minutes, and thus will become available to the garbage collector.

get

public java.nio.ByteBuffer get()

Description copied from class: SelfCleaningPool

Returns an instance of the resource T. Synchronizes on this instance for thread safety while calling internal methods to do the work. Never returns null.
