         This extension point is used to define a special viewer capable to present change objects.

&lt;p&gt;
This extension point supports the &lt;code&gt;&amp;lt;enablement&amp;gt;&lt;/code&gt; element.
&lt;!-- see org.eclipse.ltk.internal.ui.refactoring.AbstractDescriptor#matches(Object, String): --&gt;
The default variable is the change object to present a preview for.
&lt;br&gt;Defined variables for &lt;code&gt;&amp;lt;with&amp;gt;&lt;/code&gt; expressions are:
&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&quot;change&quot;: type &lt;code&gt;org.eclipse.ltk.core.refactoring.Change&lt;/code&gt;; the change object to present a preview for (same as the default variable)&lt;/li&gt;
&lt;/ul&gt;
