One-Time Events

One-time events are a special event execution mode. Whether you register synchronous or asynchronous events, the event listener can be registered to execute only once.

This mode is often used when Hasor registers a ContextEvent_Started event during init. After the application starts and fires the Started event, the event listener is automatically unregistered.

The following line registers such a listener

EventContext eventContext = ...
eventContext.pushListener("EventName",new MyListener());
