Comentários

For each method, there is a related object in the DtsEventHandlers collection that handles the event. If the event is disabled, the object will not execute and will return false. If the object does not handle the event at the local level, the event is escalated to the parent container to be handled.

These methods provide indexes into the events collection for the corresponding event handler.
