View source for Messenger Library Messaging Patterns

== Messaging Patterns ==

[[Messenger Library]] is intended to support the following patterns:
* Command: simply sending a command [[Messenger Library Messages|message]] to an [[Messenger Library Address|Address]].
* Request-Reply (blocking): sending a command and then waiting for a specific replay to come back.  Also called a "Query".
* Request-Reply Asynchronous: Sending a request with reply address attached to the message, then carrying on with other work before the reply is sent back to us. This is analogous to email.
* Scatter Gather (Blocking or Async): multi-actor versions of Request-Reply.  Makes use of Future Tokens.
* Register-Notify: Registration messages request future update "Notifications".  See the Observer Registry helper object.
