IEditorLauncher (Eclipse Platform API Specification)

```
public interface IEditorLauncher
```
An editor launcher is used to launch external editors on a file in the local file system.
Clients should implement this interface to define a new type of editor launcher. Each new launcher must be registered as an editor in the workbench's editor extension point (named "org.eclipse.ui.editors"). For example, the plug-in's XML markup might contain:
```
 <extension point = "org.eclipse.ui.editors">
   <editor
       id="org.eclipse.ui.SwingEditorLauncher"
       name="Swing Editor"
       extensions="xml"
       launcher="org.eclipse.ui.examples.swingeditor.SwingEditorLauncher"
       icon="icons/xml.gif">
   </editor>
 </extension>
 
```
In this example a launcher has been registered for use with xml files. Once registered, the launcher will appear in the Open With menu for an xml file. If the item is invoked the workbench will create an instance of the launcher class and call open on it, passing the input file.
