Class EslFrameDecoder

java.lang.Object
  org.jboss.netty.channel.SimpleChannelUpstreamHandler
      org.jboss.netty.handler.codec.replay.ReplayingDecoder<org.freeswitch.esl.client.transport.message.EslFrameDecoder.State>
          org.freeswitch.esl.client.transport.message.EslFrameDecoder

All Implemented Interfaces:

ChannelHandler, ChannelUpstreamHandler

public class EslFrameDecoder
extends ReplayingDecoder<org.freeswitch.esl.client.transport.message.EslFrameDecoder.State>

Decoder used by the IO processing pipeline. Client consumers should never need to use this class.

Follows the following decode algorithm (from FreeSWITCH wiki)

    Look for \n\n in your receive buffer

    Examine data for existence of Content-Length
 
    If NOT present, process event and remove from receive buffer
  
    IF present, Shift buffer to remove 'header'
    Evaluate content-length value
    
    Loop until receive buffer size is >= Content-length
    Extract content-length bytes from buffer and process
