Package talx.events Description

Provides system notification classes for use in other packages. The Think-and-Link system uses the Event-Listener pattern to convey messages between the controller, model and view, and to communicate within the model. Pluggable features may also generate events to alert the controller to important system events.

The controller listens for action events and uses the ActionHandlers to translate those into controller change events that are sent to the visual components. Pluggable features that wish to communicate with the controller must do so by sending an ActionEvent through the ActionDispatcher. This assumes that the controller is currently using an ActionHandler that will react to such an ActionEvent.

The model uses a filter stack with the TransportModel in the middle between the incoming filter stack and the outgoing filter stack. The TransportModel API acts as a bridge between the controller and the transport system, but the model communicates internally and to the view components through events.
