ComponentEventCallback<T>

All Known Implementing Classes:

Extends ComponentEventCallback with a way to determine if the underlying event has been aborted due to a some event returning an acceptable, non-null value. The standard implementation of this is a wrapper around either the traditional or ajax versions of the ComponentEventResultProcessor service, i.e., they allow for a navigational result.

Instances of this are made available via the Environmental annotation.

Since:

5.2.0
