Параметры

nsApplication
An NSApplication representing the Notification Services application to which this event provider delivers events.

providerName
A String containing the name of the event provider, as specified in the application definition.

args
A StringDictionary containing the names and values of the initialization arguments, as specified in the application definition.

stopDelegate
A StopHandler delegate that the event provider can use to call back to the provider host to request termination.

Note that the event provider is not initialized until the Initialize method completes. Calling stopDelegate during initialization has no effect.

Замечания

The provider host calls this method to notify the scheduled event provider that it must perform initialization. The args parameter provides the initialization arguments for the event provider. For more information about event provider arguments, see Определение внутрипроцессных поставщиков событий.

You use the values provided in the args parameter to set class variables and prepare the event provider to run. This often involves setting information about the event source that the event provider monitors and the event class that defines the events that the event provider creates.

The event provider host calls the Initialize method when it starts. The event provider returns as soon as initialization is complete. The provider host always calls Initialize before calling the Run or Terminate method.

The Initialize method has a five-minute time-out window. If initialization has not completed within that time, an error is logged and the event provider's Terminate method is called.

Пример

For an example of how to implement the Initialize method, see the IScheduledEventProvider topic.
