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 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.

Method Details

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

checkForEquivalences

protected void checkForEquivalences(Comparison comparison,
 Diff difference)

Checks the potential equivalence from the given difference.

Parameters:

comparison - The comparison this engine is expected to complete.

difference - The difference that is to be checked

checkForEquivalences

protected void checkForEquivalences(Comparison comparison,
 ReferenceChange referenceChange)

Checks the potential equivalence from the given difference.

Parameters:

comparison - The comparison this engine is expected to complete.

referenceChange - The difference that is to be checked

checkForEquivalences

protected void checkForEquivalences(Comparison comparison,
 FeatureMapChange featureMapChange)

Checks the potential equivalence from the given difference.

Parameters:

comparison - The comparison this engine is expected to complete.

featureMapChange - The difference that is to be checked
