Constructor Detail

ThreadLocalStreamBufferPool

public ThreadLocalStreamBufferPool(ByteBufferFactory byteBufferFactory,
                                   int maxThreadLocalPoolSize,
                                   int maxCorePoolSize)

Instantiate with details of pool sizes.

The total potential amount of memory used is:

pooledByteBufferSize * (active buffers + (threadLocalPoolSize * active threads) + corePoolSize).

Parameters:

byteBufferFactory - ByteBufferFactory.

maxThreadLocalPoolSize - Maximum ThreadLocal pool size.

maxCorePoolSize - Maximum core pool size.

Method Detail

Returns:

Number of StreamBuffer instances in circulation.

getPooledStreamBuffer

public StreamBuffer<java.nio.ByteBuffer> getPooledStreamBuffer()

=============== BufferPool ===========================

Specified by:

getPooledStreamBuffer in interface StreamBufferPool<java.nio.ByteBuffer>

Returns:

createThreadCompletionListener

public ThreadCompletionListener createThreadCompletionListener(ManagedObjectPool pool)

============= ThreadCompletionListenerFactory =========

Specified by:

createThreadCompletionListener in interface ThreadCompletionListenerFactory

Parameters:

pool - ManagedObjectPool.

Returns:

ThreadCompletionListener for the ManagedObjectPool.

threadComplete

public void threadComplete()

================= ThreadCompletionListener ============

Specified by:

threadComplete in interface ThreadCompletionListener
