Constructor Details

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 Details

activeThreadLocalPooling

public void activeThreadLocalPooling()

Activates ThreadLocal pooling of StreamBuffer on current Thread.

getStreamBufferCount

public int getStreamBufferCount()
