        public ProtocolOutputHandler create​(int bufferSize,
                                    int extendSize)
        Description copied from class: ProtocolOutputHandler
        Factory method to create a new ProtocolOutputHandler. For example, a RawOutputHandler returns a RawOutputHandler here.
        Specified by:
        create in class ProtocolOutputHandler
        Parameters:
        bufferSize - initial buffer size
        extendSize - extend size
        Returns:
        new protocol input handler.

      • getByteArray

        protected byte[] getByteArray()
        Description copied from class: ProtocolOutputHandler
        Returns a reference to the byte array of the current chunk to transmit. Called during invokeOutputListener().
        Specified by:
        getByteArray in class ProtocolOutputHandler
        Returns:
        byte array.

      • getOffset

        protected int getOffset()
        Description copied from class: ProtocolOutputHandler
        Returns the offset in the byte array of the current chunk where transmit should start. Called during invokeOutputListener().
        Specified by:
        getOffset in class ProtocolOutputHandler
        Returns:
        offset.

      • getLength

        protected int getLength()
        Description copied from class: ProtocolOutputHandler
        Returns the number of bytes to transmit, starting at the offset. Called during invokeOutputListener().
        Specified by:
        getLength in class ProtocolOutputHandler
        Returns:
        length.

      • setBytesWritten

        protected void setBytesWritten​(int written)
        Description copied from class: ProtocolOutputHandler
        Sets the number of bytes written from the OutputListener. This is the actual number of bytes written from the OutputListener to the network. The offset then must be set to offset+written and the length to length-written. If all bytes of the current chunk have been written, the chunk can be destroyed or marked for reuse.
        Specified by:
        setBytesWritten in class ProtocolOutputHandler
        Parameters:
        written - number of written bytes.

      • addBytes

        protected void addBytes​(byte[] b,
                        int offset,
                        int len)
        Description copied from class: ProtocolOutputHandler
        Adds a number of bytes to the current chunk. Called from write(b[],offset,len).
        Specified by:
        addBytes in class ProtocolOutputHandler
        Parameters:
        b - byte array.
        offset - offset.
        len - length.

      • markChunkCompleted

        protected void markChunkCompleted()
        Description copied from class: ProtocolOutputHandler
        Marks a chunk completed. Called during flush() If a protocol transmits byte streams with a length field in front, this is the place to determine the length.
        Specified by:
        markChunkCompleted in class ProtocolOutputHandler
