Structure Merge Viewers

Identifier:

org.eclipse.compare.structureMergeViewers

Description:

This extension point allows a plug-in to register compare/merge viewers for structural content types. The viewer is expected to extend org.eclipse.jface.viewers.Viewer. However, since viewers don't have a default constructor, the extension point must implement the factory interface for viewers org.eclipse.compare.IViewerCreator.

Configuration Markup:

<!ATTLIST extension

point CDATA #REQUIRED

id CDATA #IMPLIED

name CDATA #IMPLIED>

point - a fully qualified identifier of the target extension point

name - an optional name of the extension instance

<!ELEMENT viewer EMPTY>

<!ATTLIST viewer

id CDATA #REQUIRED

class CDATA #REQUIRED

extensions CDATA #REQUIRED

label CDATA #IMPLIED>

id - a unique identifier that can be used to reference the viewer

The following is an example of compare/merge viewer for zip files (extension "zip"):


<extension point = "org.eclipse.compare.structureMergeViewers"> 
     <viewer 
         id="org.eclipse.compare.ZipCompareViewer" 
         class="org.eclipse.compare.ZipCompareViewerCreator"
