object_protocol

== DESCRIPTION:
An Object Protocol for ruby. Simply implements send and receive using a 
serializer that responds to #dump and #load. This protocol does not handle the 
"packetization" or framing of data. This should be performed by an external 
handler such as my sized_header_protocol.
== FEATURES/PROBLEMS:
* Simplicity.
* Accepts any serializer supporting #dump and #load.
* Part of the API feels a bit clunky when chaining.
* Needs it's documentation filling in.
== SYNOPSIS:
The following example is an example designed to run with EventMachine and 
sized_header_protocol. See the docs for sized_header_protocol for more 
information regarding the chaining api setup.
Provide any serializer supporting #dump and #load. Known options include:
* Marshal
* YAML
* JSON
I'm sure there must be others too.
  require 'rubygems'
  require 'eventmachine'
  require 'sized_header_protocol'
  require 'object_protocol'
  module Op
    def post_init
      @serializer = Marshal
      @packr = SizedHeaderProtocol.new(self, :send_data, nil, :receive_data)
      @proto = ObjectProtocol.new(@packr, :send_data, self, :receive_object, @serializer)
      @packr.read_obj = @proto
    end
    def receive_data(data)
      @packr.receive_data(data)
    end
    def send_object(object)
      @proto.send_data(object)
    end
    def receive_object(object)
      p object
      send_object(object.reverse)
    end
  end
  EM.run do
    EM.start_server '127.0.0.1', 8000, Op do |c|
      EM.add_timer(0.1) { c.send_object [:from, :server] }
    end
    EM.connect '127.0.0.1', 8000, Op do |c|
      EM.add_timer(0.1) { c.send_object [:from, :client] }
    end
    EM.add_timer(0.5) { EM.stop }
  end
Also, for further details or explanation, see the test (spec) suite.
== REQUIREMENTS:
* A packetization lib (sized_header_protocol)
* A transport system (eventmachine / packet / rev)
* Bacon for the spec suite.
== INSTALL:
* sudo gem install object_protocol
