module Adaptation
#= Adaptation::Adaptor -- The message processor
#
#Adaptation::Adaptor is the base class for those classes containing the logic to be executed when a message is read through the mom. 
#
#Each class extending Adaptation::Adaptor must implement the _process_ function, using it as the main entry point for the logic to be executed when a message arrives. The name of the class extending Adaptation::Message associates the class with the one to be executed when a message arrives. Ie. if a message is received with a root element named <hello>, adaptation will search for a class extending Adaptation::Adaptor named _HelloAdaptor_. 
#
#<i>Adaptation::Adaptors</i> (classes extending Adaptation::Adaptor) must be stored under <i>app/adaptors_name</i> in the adaptation file tree. This is done automatically when an adaptor is generated using adaptation built-in generator:
#  script/generate adaptor hello
# 
  class Adaptor

    def process message
    end

      Adaptation::Base.logger

        xml_message = options.first
        message_type = xml_message[1..(xml_message.index(/(>| )/) - 1)]
        message_class = Adaptation::Message.get_class_object(message_type.capitalize)
        message_object = message_class.to_object(xml_message)
