# Defines some default marshaling strategies for use in marshaling/unmarshaling objects
# written and read via jms.  Implementing classes must define the following methods:
#
#   # Return symbol
#   #  :text  if session.create_text_message should be used to generate the JMS message
#   #  :bytes if session.create_bytes_message should be used to generate the JMS message
#   def marshal_type
#     # Return either :text or :bytes
#     :text
#   end
#
#   # Defines the conversion to wire format by the publisher of the message
#   def marshal(object)
#     # Operate on object and convert to message format
#   end
#
#   # Defines the conversion from wire format by the consumer of the message
#   def unmarshal(msg)
#     # Operate on message to convert it from wire protocol back to object format
#   end
