Interface ProtocolEncoderOutput

All Known Implementing Classes:

AbstractProtocolEncoderOutput, ProtocolCodecFilter.ProtocolEncoderOutputImpl

public interface ProtocolEncoderOutput

Callback for ProtocolEncoder to generate encoded messages such as IoBuffers. ProtocolEncoder must call write(Object) for each encoded message.

Method Summary

Modifier and Type	Method	Description
WriteFuture	flush()	Flushes all buffers you wrote via write(Object) to the session.
void	mergeAll()	Merges all buffers you wrote via write(Object) into one IoBuffer and replaces the old fragmented ones with it.
void	write(Object encodedMessage)	Callback for ProtocolEncoder to generate an encoded message such as an IoBuffer.

Method Details

write

void write(Object encodedMessage)

Callback for ProtocolEncoder to generate an encoded message such as an IoBuffer. ProtocolEncoder must call write(Object) for each encoded message.

Parameters:

encodedMessage - the encoded message, typically an IoBuffer or a FileRegion.

mergeAll

void mergeAll()

Merges all buffers you wrote via write(Object) into one IoBuffer and replaces the old fragmented ones with it. This method is useful when you want to control the way MINA generates network packets. Please note that this method only works when you called write(Object) method with only IoBuffers.

Throws:

IllegalStateException - if you wrote something else than IoBuffer

flush

WriteFuture flush()

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

Returns:

null if there is nothing to flush at all.
