acquire

public java.nio.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 but it will have the limit set to the given size.

Specified by:

acquire in interface ByteBufferPool

Parameters:

size - the size of the buffer

direct - whether the buffer must be direct or not

Returns:

the requested buffer

ByteBufferPool.release(ByteBuffer)

release

public void release(java.nio.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
