Interface ERXLongResponseTask

All Superinterfaces:

java.lang.Runnable

All Known Implementing Classes:

ERXLongResponseTask.DefaultImplementation

public interface ERXLongResponseTask
extends java.lang.Runnable

Long response task interface and default implementation should take away the need to tie your long running task directly to a component like with WOLongReponsePage. To use it, you should subclass the default implementation, implement performAction(), drop an instance of ERXLongResponse on your page and bind it's task binding to it.
