Messages |
A message indicates a communication between objects. The order of messages from top to bottom on your diagram should be the order in which the messages occur.
A message can be from an object to itself.
A return message indicates a response from a message (rather than a new message) and is shown on the diagram as a dashed line.
A recursive message is one that calls itself.
An asynchronous message doesn't block the object that makes the call so that the object can carry on with it's own processing without waiting for a response.
