cleanup

protected void cleanup()

Overrides:

force

public void force()

sliceAsByteBuffer

public ByteBuffer sliceAsByteBuffer(ByteBuffer toReuse)

Description copied from interface: BytesCommon

Returns a ByteBuffer whose content is a shared subsequence of this bytes' content.

The content of the returned ByteBuffer will start at this bytes' current position. Changes to this bytes' content will be visible in the returned ByteBuffer, and vice versa; this bytes' and the returned ByteBuffer's position and limit values will be independent.

The returned ByteBuffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this bytes.

If this bytes object is able to reuse to given toReuse ByteBuffer, it will be reused and returned back from this method, otherwise a new ByteBuffer instance is created and returned.

Specified by:

sliceAsByteBuffer in interface BytesCommon

Overrides:

sliceAsByteBuffer in class NativeBytes

Parameters:

toReuse - a ByteBuffer to reuse

Returns:

a ByteBuffer view of this Bytes

BytesCommon.slice(), ByteBuffer.slice()
