Constructor Details

ByTypeIndex

public ByTypeIndex(ProximityEObjectMatcher.DistanceFunction meter,
 ScopeQuery scope)

Create a new instance using the given ProximityEObjectMatcher.DistanceFunction to instantiate delegate indexes on demand.

Parameters:

meter - the function passed when instantiating delegate indexes.

scope - an instance

Method Details

getValuesStillThere

public Iterable<EObject> getValuesStillThere(EObjectIndex.Side side)

return the list of EObjects of a given side still available in the index.

Specified by:

getValuesStillThere in interface EObjectIndex

Parameters:

side - the side we are looking for.

Returns:

the list of EObjects of a given side still available in the index.

See Also:

• EObjectIndex.getValuesStillThere(org.eclipse.emf.compare.match.eobject.EObjectIndex.Side)

findClosests

public Map<EObjectIndex.Side,EObject> findClosests(Comparison inProgress,
 EObject obj,
 EObjectIndex.Side side)

Return the closest EObjects found in other sides than the one given.

Specified by:

findClosests in interface EObjectIndex

Parameters:

inProgress - the comparison currently being computed. It will not be changed directly but only queried to know if some element has already been matched or not.

obj - the base EObject used to lookup similar ones.

side - the side of the passed EObject.

Returns:

a map of Side, EObjects, returning all the found objects (and the passed one) which are the closests.

See Also:

• org.eclipse.emf.compare.match.eobject.EObjectIndex#findClosests(org.eclipse.emf.ecore.EObject, org.eclipse.emf.compare.match.eobject.EObjectIndex.Side, int)

remove

public void remove(EObject obj,
 EObjectIndex.Side side)

Remove an object from the index.

Specified by:

remove in interface EObjectIndex

Parameters:

obj - object to remove.

side - Side in which this object was.

See Also:

• EObjectIndex.remove(org.eclipse.emf.ecore.EObject, org.eclipse.emf.compare.match.eobject.EObjectIndex.Side)

index

public void index(EObject eObjs,
 EObjectIndex.Side side)

Register an Object in the index with the given side.

Specified by:

index in interface EObjectIndex

Parameters:

eObjs - the EObject to register.

side - the side in which it should be registered.

See Also:

• EObjectIndex.index(org.eclipse.emf.ecore.EObject, org.eclipse.emf.compare.match.eobject.EObjectIndex.Side)

getValuesToMatchAhead

public Iterable<EObject> getValuesToMatchAhead(EObjectIndex.Side side)

Return EObjects to match ahead of time if there are some.

Specified by:

getValuesToMatchAhead in interface MatchAheadOfTime

Parameters:

side - the side to look for.

Returns:

the EObjects to match ahead of time.
