org.eclipse.emf.compare.diff.engine
Interface IDiffEngine

All Known Implementing Classes:

GenericDiffEngine

public interface IDiffEngine

A Diff engine has the responsability to provide a diff (or delta) model from a matching model.

Method Summary

DiffModel	doDiff(MatchModel match) Return a diffmodel created using the match model.
DiffModel	doDiff(MatchModel match, boolean threeWay) Return a diffmodel created using the match model.
DiffModel	doDiffResourceSet(MatchModel match, boolean threeWay, org.eclipse.emf.ecore.util.EcoreUtil.CrossReferencer crossReferencer) Return a diffmodel created using the given match model.
void	reset() This will be called with each access from the service to the singleton instance of this engine.

Method Detail

doDiff

DiffModel doDiff(MatchModel match)

Return a diffmodel created using the match model. This implementation is a generic and simple one.

Parameters:

match - The matching model.

Returns:

The corresponding diff model.

doDiff

DiffModel doDiff(MatchModel match,
                 boolean threeWay)

Return a diffmodel created using the match model. This implementation is a generic and simple one.

Parameters:

match - the matching model

threeWay - True if we're computing a three way comparison, False otherwise.

Returns:

the corresponding diff model

doDiffResourceSet

DiffModel doDiffResourceSet(MatchModel match,
                            boolean threeWay,
                            org.eclipse.emf.ecore.util.EcoreUtil.CrossReferencer crossReferencer)

Return a diffmodel created using the given match model. crossReferencer has been initialized on the whole MatchResourceSet.

Parameters:

match - the matching model

threeWay - True if we're computing a three way comparison, False otherwise.

crossReferencer - This cross referencer has been initialized with the whole MatchResourceSet and can be used to retrieve matched EObjects towards other resources.

Returns:

the corresponding diff model

reset

void reset()

This will be called with each access from the service to the singleton instance of this engine. Clients should dispose of all caches and recorded information within this method's implementation.
