Adding extension points to compare and merge projects

You can add extension points to a compare and merge project that was generated by the Create Compare and Merge Project wizard.

Before you begin

You must have a custom compare and merge project.

Procedure

  1. In the Package Explorer or Project Explorer view, right-click an existing compare and merge project; then click File > New > Other.
  2. In the New wizard, expand Modeling > Compare Merge Extensibility; then click one of the following extension points and click Next:
    • Composite Delta Strategy
    • Conflict Strategy
    • Delta Tree Filter
    • Delta Tree Structure Builder
    • Sub-Session Merge Extender
  3. In the wizard, follow the instructions to specify the extension point and click Finish.

Results

The extension point declarations are inserted into the plugin.xml file and the required Java classes are generated. The extensions that have user interfaces, such as delta tree filters, delta tree structure builders, and sub-session merge extenders, are displayed in both compare and merge sessions and fuse sessions for that content type.
