clojurewerkz.meltdown.reactor
Provides key reactor and message passing operations:
- Reactor instantiation
- Registration (subscription) for events
- Event notifications
Provides key reactor and message passing operations: * Reactor instantiation * Registration (subscription) for events * Event notifications
createclj
(create & {:keys [dispatcher-type event-routing-strategy env dispatcher]})Creates a reactor instance.
A new router is instantiated for every reactor, otherwise reactors will needlessly share state
Creates a reactor instance. A new router is instantiated for every reactor, otherwise reactors will needlessly share state
maybe-wrap-eventclj
(maybe-wrap-event ev)Coerces given into to an Event instance
Coerces given into to an Event instance
notifyclj
(notify reactor payload)(notify reactor key payload)(notify reactor key payload completion-fn)Broadcasts a event instantiated from provided payload (data structure)
Broadcasts a event instantiated from provided payload (data structure)
onclj
(on reactor selector f)Registers a Clojure function as event handler for a particular kind of events.
Registers a Clojure function as event handler for a particular kind of events.
on-errorclj
(on-error reactor exception-type f)Registers a Clojure function as event handler for a class of Exception.
Registers a Clojure function as event handler for a class of Exception.
receive-eventclj
(receive-event reactor selector f)Same as notify, except it checks for reply-to and sends a resulting callback. Used for optimization, since checking for reply-to is a (relatively) expensive operation

register-consumerclj
(register-consumer reactor consumer)(register-consumer reactor selector consumer)Registers a Clojure function as event handler for a particular kind of events.
Registers a Clojure function as event handler for a particular kind of events.
responds-to?clj
(responds-to? reactor key)Returns true if provded reactor has consumers registered for a particular key
Returns true if provded reactor has consumers registered for a particular key
