Method Detail

reallocate

ByteBuffer reallocate(ByteBuffer oldByteBuffer,
                      int newSize)

Creates a new Buffer with a set size and assigns it the data that was held in the old one as long as the given size is not smaller than the data held.

Parameters:

oldByteBuffer - Old Buffer containing data

newSize - The size the new Buffer should be.

Returns:

the new Buffer or null if the buffer could not be resized

release

boolean release(ByteBuffer byteBuffer)

deallocates the data in the buffer

Parameters:

byteBuffer - the buffer to release

Returns:

true if operation successfully completed, false otherwise

reduceLastAllocated

ByteBuffer reduceLastAllocated(ByteBuffer byteBuffer)

Reduces the buffer to the last data allocated

Parameters:

byteBuffer -

Returns:

the old buffer data that was removed. This may be null.

remaining

int remaining()

Gets the number of elements between the current position and the limit

Returns:

number of elements

reset

void reset(T byteBuffer)

Resets the Buffer to empty values and empties the pool

Parameters:

byteBuffer - the buffer to reset

allocate

T allocate(int size)

Creates a buffer with a given capacity and limit

Parameters:

size - maximum number of elements

Returns:

the new buffer

See Also:

ByteBuffer.allocate(int)

hasRemaining

boolean hasRemaining()

Whether there are elements between the current position and the end

Returns:

true if there are unused elements, false otherwise

getMaxBufferSize

int getMaxBufferSize()

The Max Buffer Size for buffer

Returns:

the max buffer size.

dispose

void dispose()

dospose the thread local pool.
