TrackableComponentEventCallback (Tapestry API - 5.8.6)

All Superinterfaces:

ComponentEventCallback<T>

All Known Implementing Classes:

ComponentResultProcessorWrapper
```
public interface TrackableComponentEventCallback<T>
extends ComponentEventCallback<T>
```
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
