View source for FAQ How do I find all the plug-ins that contribute to my extension point?

Assuming that you used an element attribute named <tt>class</tt> to encode
the name of the class that your contributors have to provide, you
can obtain a list of all the plug-in classes that contribute to your extension point
by using the following piece of code:
<pre>
   IExtensionRegistry reg = Platform.getExtensionRegistry();
   IExtensionPoint ep = reg.getExtensionPoint(extensionID);
   IExtension[] extensions = ep.getExtensions();
   ArrayList contributors = new ArrayList();
   for (int i = 0; i &lt; extensions.length; i++) {
      IExtension ext = extensions[i];
      IConfigurationElement[] ce = 
         ext.getConfigurationElements();
      for (int j = 0; j &lt; ce.length; j++) {
         Object obj = ce[j].createExecutableExtension("class");
         contributors.add(obj);
      }
   }
</pre>
From a given extension point, it is straightforward to get a list of
extensions that contribute to it. For each extension, we create
an executable extension using the value of the <tt>class</tt> property.
We save all the executable extensions in an array list and return it.

You can also get all IConfigurationElement objects without retrieving each extension by using following code:
<pre>
    IExtensionRegistry reg = Platform.getExtensionRegistry();
    IConfigurationElement[] elements = reg.getConfigurationElementsFor("Extension Point ID");
</pre>
