Package org.eclipse.emf.compare.equi

Class DefaultEquiEngine

java.lang.Object
org.eclipse.emf.compare.equi.DefaultEquiEngine
All Implemented Interfaces:
IEquiEngine
public class DefaultEquiEngine
extends java.lang.Object
implements IEquiEngine
The requirements engine is in charge of actually computing the equivalences between the differences.

This default implementation aims at being generic enough to be used for any model, whatever the metamodel. However, specific requirements might be necessary.

TODO document available extension possibilities.

    • computeEquivalences

      public void computeEquivalences​(Comparison comparison, Monitor monitor)
      This is the entry point of the equivalence computing process.

      It will complete the input comparison by iterating over the differences it contain, filling in the equivalence it can detect for each distinct Diff.

      Specified by:
      computeEquivalences in interface IEquiEngine
      Parameters:
      comparison - The comparison this engine is expected to complete.
      monitor - The monitor to report progress or to check for cancellation
