Watch Expression Delegates

Identifier:
org.eclipse.debug.core.watchExpressionDelegates

Since:
3.0

Description:
This extension provides a mechanism for providing delegates to evaluate watch expressions on a per debug model basis. Watch expression delegates perform evaluations for watch expressions and report the results asynchronously.

Configuration Markup:

<!ELEMENT extension ( watchExpressionDelegate*)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED

>

  • point - a fully qualified identifier of the target extension point
  • 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>
