###### Identifier:

org.eclipse.debug.core.watchExpressionDelegates

###### Since:

###### Configuration Markup:

<!ELEMENT extension (watchExpressionDelegate*)>

<!ATTLIST extension

id CDATA #IMPLIED

name CDATA #IMPLIED>

- id - an optional identifier of the extension instance
- name - an optional name of the extension instance

<!ELEMENT watchExpressionDelegate EMPTY>

<!ATTLIST watchExpressionDelegate

debugModel CDATA #REQUIRED

delegateClass CDATA #REQUIRED>

- debugModel - specifies the id of the debug model that this delegate provides evaluations for
- delegateClass - specifies a Java class which implements `org.eclipse.debug.core.model.IWatchExpressionDelegate`, which is used to evaluate the value of an expression.

###### Examples:

    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>

###### API Information:

Value of the attribute delegateClass must be a fully qualified name of a Java class that implements the interface org.eclipse.debug.core.model.IWatchExpressionDelegate.
