Class MemcachedFrameDecoder

  extended by
      extended by org.jboss.netty.handler.codec.frame.FrameDecoder
          extended by org.openspaces.memcached.protocol.text.MemcachedFrameDecoder
All Implemented Interfaces:,

public final class MemcachedFrameDecoder
extends org.jboss.netty.handler.codec.frame.FrameDecoder

The frame decoder is responsible for breaking the original stream up into a series of lines.

The code here is heavily based on Netty's DelimiterBasedFrameDecoder, but has been modified because the memcached protocol has two states: 1) processing CRLF delimited lines and 2) spooling results for SET/ADD
