It is my first project using mina and I have to admit that I may not really understand the idea of Filter or ProtocolCodecFilter chaining. I am implementing a client for a custom binary tcp protocol, extending from DemuxingProtocolCodecFactory. Everything working so far, encoding and sending RequestMessages and also receiving and decoding ResponseMessages. Now one of my MessageEncoders needs to encode a file in blocks of 512byte add some additional bytes like magic and crc (don't ask!) to it and sends it. I am trying to use the FileRegionWriteFilter for it but can not figure it out how I can set up the filter chain.
Like for all the other RequestMessages I have an pojo with a file handle and an Encoder class which implements MessageEncoder<T> and should only encode a chunk of 512bytes. Like the other MessageEncoders these are set up like this: super.addMessageEncoder(WriteFile.class, WriteFileEncoder.class); But in contrast to the other MessageEncoders which are set-up in a factory like this: "super.addMessageEncoder(Data.class, DataEncoder.class)" and where each data-class relates exactly to one encoder-class, for the "FileEncoder" I need to call "encode()" many times. Now how can I add a FileRegionWriteFilter and use FileRegions for the data-chunks? -- View this message in context: http://apache-mina.10907.n7.nabble.com/help-with-FileRegionWriteFilter-tp39754.html Sent from the Apache MINA User Forum mailing list archive at Nabble.com.
