This service handles what should happen when you get an event. This service does
|
|
not care where the event came from, it only needs enough context to be able to
|
|
process them. Events may be coming from the event stream, the REST API (via
|
|
direct GETs or via a pagination stream API), etc.
|
|
|
|
Typically, this service will store events or broadcast them to any listeners
|
|
(e.g. controllers) via $broadcast. Alternatively, it may update the $rootScope
|
|
if typically all the $on method would do is update its own $scope.
