Examples of java.nio.ByteBuffer.compact()

java.nio.ByteBuffer.compact()
Compacts this byte buffer.
The remaining bytes will be moved to the head of the buffer, staring from position zero. Then the position is set to remaining(); the limit is set to capacity; the mark is cleared.
@return This buffer @exception ReadOnlyBufferException If no changes may be made to the contents of this buffer
