Method Details

newByteBuffer

public ByteBuffer newByteBuffer(int capacity,
 boolean direct)

Description copied from interface: ByteBufferPool

Creates a new ByteBuffer of the given capacity and the given directness.

Parameters:

capacity - the ByteBuffer capacity

direct - the ByteBuffer directness

Returns:

a newly allocated ByteBuffer

asRetainableByteBufferPool

public RetainableByteBufferPool asRetainableByteBufferPool()

Description copied from interface: ByteBufferPool

Get this pool as a RetainableByteBufferPool, which supports reference counting of the buffers and possibly a more efficient lookup mechanism based on the Pool class.

Specified by:

asRetainableByteBufferPool in interface ByteBufferPool

Returns:

This pool as a RetainableByteBufferPool. The same instance is always returned by multiple calls to this method.
