Method Detail

getCoveredResources
public Iterator<? extends Resource> getCoveredResources(ResourceSet resourceSet)
This will be used by EMF Compare in order to determine the Resources that should be considered part of the comparison when it is launched on the given resource set.Do note that this will only be called once per Resource. We will retrieve the set of EMF resources to include in the comparison, match them, then use
IComparisonScope.getCoveredEObjects(Resource)
in order to determine the actual EObjects to cover during that comparison.- Parameters:
resourceSet
- The resource set for which we need to know all resources spanned by the comparison.- Returns:
- An iterator over the
Resource
s which are part of this scope.
-
getCoveredEObjects
public Iterator<? extends EObject> getCoveredEObjects(Resource resource)
This will be used by EMF Compare in order to determine the EObjects that it should iterate over.Do note that this will only be called once per comparison. EMF Compare expects this to return the whole set of EObjects that should be covered by the comparison when launched on the given Resource.
- Parameters:
resource
- The resource for which we need to determine all EObjects spanned by the comparison.- Returns:
- An iterator over the
EObject
s which are part of this scope.
-
getChildren
public Iterator<? extends EObject> getChildren(EObject eObject)
This will be used by EMF Compare in order to know which EObjects should be considered to be part of the comparison scope when it is launched on the given EObject.Do note that this will only be called once per comparison on EObjects, and never for comparisons launched on
ResourceSet
s orResource
s. EMF Compare expects the whole set of EObject that should be covered by the comparison to be returned by this.- Parameters:
eObject
- The EObject for which we need to determine the comparison scope.- Returns:
- An iterator over the
EObject
s which are part of this scope.
