public static void removeGroups(Collection<? extends org.eclipse.emf.ecore.EObject> objects,
                Set<String> groupIds)

Remove exclusive groups from a collection of objects

Parameters:

objects - the objects to process

groupIds - the groups to remove

findAnnotation

public static org.eclipse.emf.ecore.EAnnotation findAnnotation(org.eclipse.emf.ecore.EObject target)

Finds the annotation even on supertypes

Parameters:

target - the object to check

Returns:

the annotation or null the object or its supertypes don't have the annotation

makeGroupIds

public static Set<String> makeGroupIds(Collection<? extends org.eclipse.emf.ecore.EObject> objects)

Make a set of group ids present in the object collection

Parameters:

objects - the objects to check

Returns:

the group set, never null

removeGroups

public static void removeGroups(Collection<? extends org.eclipse.emf.ecore.EObject> objects,
                Collection<? extends org.eclipse.emf.ecore.EObject> sourceObjects)

Remove all exclusive objects that are in the one group from the other

Parameters:

objects - the object from which objects will be removed

sourceObjects - the source of the exclusive group objects

validate

public static Map<String,Set<org.eclipse.emf.ecore.EObject>> validate(org.eclipse.emf.common.util.EList<? extends org.eclipse.emf.ecore.EObject> objects)

Return an aggregated map of group violations

This method actually calls aggregateGroups(EList) and only returns groups with a size greater than 1.

Parameters:

objects - the objects to validate

Returns:

the map of group violations

aggregateGroups

public static Map<String,Set<org.eclipse.emf.ecore.EObject>> aggregateGroups(org.eclipse.emf.common.util.EList<? extends org.eclipse.emf.ecore.EObject> objects)

Group objects by groupId

Note that object without are group are not returned
