Compare Merge Content Viewers

Identifier:

com.ibm.xtools.comparemerge.ui.compareMergeContentViewers

Description:

This extension point allows a plug-in to register compare/merge content viewers for specific file extensions. 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 com.ibm.xtools.comparemerge.ui.internal.services.IContentViewerCreator. The viewer creator should return the interface com.ibm.xtools.comparemerge.ui.viewers.IContentViewer
