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.
