Constructor Detail

SimpleProtocolEncoderOutput

public SimpleProtocolEncoderOutput()

Method Detail

getBufferQueue

public Queue<ByteBuffer> getBufferQueue()

write

public void write(ByteBuffer buf)

Description copied from interface: ProtocolEncoderOutput

Callback for ProtocolEncoder to generate encoded ByteBuffers. ProtocolEncoder must call ProtocolEncoderOutput.write(ByteBuffer) for each encoded message.

Specified by:

write in interface ProtocolEncoderOutput

Parameters:

buf - the buffer which contains encoded data

mergeAll

public void mergeAll()

Description copied from interface: ProtocolEncoderOutput

Merges all buffers you wrote via ProtocolEncoderOutput.write(ByteBuffer) into one ByteBuffer and replaces the old fragmented ones with it. This method is useful when you want to control the way MINA generates network packets.

Specified by:

mergeAll in interface ProtocolEncoderOutput

flush

public WriteFuture flush()

Description copied from interface: ProtocolEncoderOutput

Flushes all buffers you wrote via ProtocolEncoderOutput.write(ByteBuffer) to the session. This operation is asynchronous; please wait for the returned WriteFuture if you want to wait for the buffers flushed.

Specified by:

flush in interface ProtocolEncoderOutput

Returns:

null if there is nothing to flush at all.

doFlush

protected abstract WriteFuture doFlush(ByteBuffer buf)
