Modifier and Type	Method	Description
ByteBuffer	acquire(int size, boolean direct)	Requests a ByteBuffer of the given size.
RetainableByteBufferPool	asRetainableByteBufferPool()	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.
void	release(ByteBuffer buffer)	Returns a ByteBuffer, usually obtained with ByteBufferPool.acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.

Method Details

acquire

public ByteBuffer acquire(int size,
 boolean direct)

Description copied from interface: ByteBufferPool

Requests a ByteBuffer of the given size.

The returned buffer may have a bigger capacity than the size being requested.

Specified by:

acquire in interface ByteBufferPool

Parameters:

size - the size of the buffer

direct - whether the buffer must be direct or not

Returns:

a buffer with at least the requested capacity, with position and limit set to 0.

• ByteBufferPool.release(ByteBuffer)

release

public void release(ByteBuffer buffer)

Description copied from interface: ByteBufferPool

Returns a ByteBuffer, usually obtained with ByteBufferPool.acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.

Specified by:

release in interface ByteBufferPool

Parameters:

buffer - the buffer to return

See Also:

• ByteBufferPool.acquire(int, boolean)

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.
