Syntax

public interface ActivateInterestListener
The DOFSystemActivateInterestListener type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | activate |
This method is called when
DOFInterestLevel.ACTIVATE
-level interest (and higher) is expressed
for an interface on an object. The provider should start
providing the binding. Guard against calling beginProvide multiple times for the same objectID
and interfaceID since this method will be called for every interest received at this level.
|
| cancelActivate |
This method is called when
DOFInterestLevel.ACTIVATE
-level interest (and higher) is complete (no longer desired)
for an interface on an object. The provider should
stop providing the binding if there is no other ACTIVATE-level interest remaining. Call
DOFObject.isInterestRequested(DOFInterfaceID, DOFInterestLevel)
to determine if
any interest remains on this binding.
|
| removed | This method is called when this listener is removed from the DOFSystem. |
