Method Details

referenceChange

public void referenceChange(Match match,
 EReference reference,
 EObject value,
 DifferenceKind kind,
 DifferenceSource source)

This will be called whenever the Diff engine detected a difference for a given reference value.

Specified by:

referenceChange in interface IDiffProcessor

Parameters:

match - The match to which this difference should be attached.

reference - The reference on which we detected a difference.

value - The actual value for which we detected a difference.

kind - Kind of the detected difference.

source - Source of the detected difference. For two way comparisons, this will always be DifferenceSource.LEFT. Otherwise, this will indicate the side on which this difference has been detected.

• IDiffProcessor.referenceChange(org.eclipse.emf.compare.Match, org.eclipse.emf.ecore.EReference, org.eclipse.emf.ecore.EObject, org.eclipse.emf.compare.DifferenceKind, org.eclipse.emf.compare.DifferenceSource)

attributeChange

public void attributeChange(Match match,
 EAttribute attribute,
 Object value,
 DifferenceKind kind,
 DifferenceSource source)

This will be called whenever the diff engine detected a difference for a given attribute value.

Specified by:

attributeChange in interface IDiffProcessor

Parameters:

match - The match to which this difference should be attached.

attribute - The attribute on which we detected a difference.

value - The actual value for which we detected a difference.

kind - Kind of the difference.

source - Source of the difference. For two way comparisons, this will always be DifferenceSource.LEFT. Otherwise, this will indicate the side on which this difference has been detected.

• IDiffProcessor.attributeChange(org.eclipse.emf.compare.Match, org.eclipse.emf.ecore.EAttribute, java.lang.Object, org.eclipse.emf.compare.DifferenceKind, org.eclipse.emf.compare.DifferenceSource)

featureMapChange

public void featureMapChange(Match match,
 EAttribute attribute,
 Object value,
 DifferenceKind kind,
 DifferenceSource source)

This will be called whenever the diff engine detected a difference for a given attribute value.

Specified by:

featureMapChange in interface IDiffProcessor

Parameters:

match - The match to which this difference should be attached.

attribute - The EFeatureMapEntry attribute on which we detected a difference.

value - The actual FeatureMap.Entry value for which we detected a difference.

kind - Kind of the difference.

source - Source of the difference. For two way comparisons, this will always be DifferenceSource.LEFT. Otherwise, this will indicate the side on which this difference has been detected.

Since:

3.2

resourceAttachmentChange

public void resourceAttachmentChange(Match match,
 String uri,
 DifferenceKind kind,
 DifferenceSource source)

This will be called whenever the diff engine detected the addition (or removal) of a root in a given Resource.

Specified by:

resourceAttachmentChange in interface IDiffProcessor

Parameters:

match - The match to which this difference should be attached.

uri - The uri of the resource we attached this element to in case of an DifferenceKind.ADD , or the uri of the resource it was attached to in case of a DifferenceKind.DELETE difference.

kind - Kind of this difference.

source - Source of the difference. For two way comparisons, this will always be DifferenceSource.LEFT. Otherwise, this will indicate the side on which this difference has been detected.

resourceLocationChange

@Deprecated
public void resourceLocationChange(MatchResource matchResource,
 String baseLocation,
 String changedLocation,
 DifferenceKind kind,
 DifferenceSource source)

Deprecated.

ResourceLocationChanges have been replaced by ResourceAttachmentChanges of kind Move.

This will be called whenever the diff engine detects the change of a Resource location.

Specified by:

resourceLocationChange in interface IDiffProcessor

Parameters:

matchResource - The matchResource to which this difference should be attached.

baseLocation - The base location (left side in case of a two way comparison, origin or left side in case of a three way comparison).

changedLocation - The change location (right side in case of a two way comparison, left or right side in case of a three way comparison).

kind - Kind of this difference.

source - Source of the difference. For two way comparisons, this will always be DifferenceSource.LEFT. Otherwise, this will indicate the side on which this difference has been detected.
