Package org.eclipse.debug.core.model

Interface IWatchExpressionDelegate

public interface IWatchExpressionDelegate
A delegate which computes the value of a watch expression when provided a context. Watch delegates are provided on a per debug model basis. Watch expressions query the appropriate delegate based on the debug model of the context element. Plug-ins that wish to contribute watch expression delegates may do so using the org.eclipse.debug.core.watchExpressionDelegates extension point.

For example, the following is the definition of a watch expression delegate for the com.example.foo plug-in: 

 <extension point="org.eclipse.debug.core.watchExpressionDelegates">
   <watchExpressionDelegate
     debugModel="org.eclipse.jdt.debug"
     delegateClass="org.eclipse.jdt.internal.debug.ui.JavaWatchExpressionDelegate"/>
  </extension>

Clients are intended to implement this interface.
