        Deprecated.
        Description copied from class: ByteBuf
        Transfers the content of the specified source channel starting at the given file position to this buffer starting at the specified absolute index. This method does not modify readerIndex or writerIndex of this buffer. This method does not modify the channel's position.
        Specified by:
        setBytes in class ByteBuf
        position - the file position at which the transfer is to begin
        length - the maximum number of bytes to transfer
        Returns:
        the actual number of bytes read in from the specified channel. -1 if the specified channel is closed or reached EOF.
        Throws:
        java.io.IOException - if the specified channel threw an exception during I/O

        Deprecated.
        Description copied from class: ByteBuf
        Exposes this buffer's bytes as an NIO ByteBuffer's for the specified index and length The returned buffer either share or contains the copied content of this buffer, while changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this buffer. This method does not modify readerIndex or writerIndex of this buffer. Please note that the returned NIO buffer will not see the changes of this buffer if this buffer is a dynamic buffer and it adjusted its capacity.
