Method Detail

getReferencedMetamodels

public java.util.Set<Metamodel> getReferencedMetamodels(Metamodel metamodel)

Gets all metamodels in the modular reference structure, on which the metamodel passed as parameter depend.

Parameters:

metamodel - the metamodel being inspected

Returns:

the set of the metamodels

getExtendedMetamodels

public java.util.Set<Metamodel> getExtendedMetamodels(Metamodel metamodel)

getExtendingStereotypes

public java.util.Set<org.modelversioning.emfprofile.Stereotype> getExtendingStereotypes(Metamodel extendingMetamodel,
                                                                                        Metamodel extendedMetamodel)

printStereotypes

public java.lang.String printStereotypes(org.eclipse.sirius.diagram.DDiagramElement view)

getAllMetamodels

public static java.util.Collection<Metamodel> getAllMetamodels(ModularReferenceStructure mrs)

Returns all metamodels present in the ModularReferenceStructure

Parameters:

mrs - the ModularReferenceStructure

Returns:

a Collection containing the metamodels

getTopMostPackage

public static EPackage getTopMostPackage(EPackage ePackage)

Returns the main EPackage of the metamodel containing ePackage

Parameters:

ePackage -

Returns:

ePackage if it has no super package, otherwise the top most package of the super package of ePackage

edgeIsPointingDownwards

public boolean edgeIsPointingDownwards(org.eclipse.sirius.diagram.DEdge edge)

Checks whether the edge is pointing from a layer to a lower one

Parameters:

edge -

Returns:

true if edge points to a metamodel in a lower layer, false otherwise

edgeIsPartOfCycle

public boolean edgeIsPartOfCycle(org.eclipse.sirius.diagram.DEdge edge)

Checks whether there is a cycle containing the edge by running a variant of Breadth First Search starting from the target of the edge and checking if the edge's source can be reached

Parameters:

edge -

Returns:

true if a cycle containing edge is discovered

getContainingMetamodel

public Metamodel getContainingMetamodel(org.eclipse.sirius.diagram.DNodeContainer containerView)

This method returns the metamodel containing the semantic element of the container view

Parameters:

containerView - a graphical element in the diagram. Must be inside a Metamodel

Returns:

the metamodel

getEAllSubPackages

public java.util.Collection<EPackage> getEAllSubPackages(EPackage ePackage)

Gets all subpackages of ePackage recursively

Parameters:

ePackage -

Returns:

a Collection of all subpackages

getAllPackages

public java.util.Collection<EPackage> getAllPackages(EPackage ePackage)

getChainOfContainers

public java.util.List<EObject> getChainOfContainers(EObject eObject,
                                                    EObject topMostContainer)

Computes the containment chain of the given EObject

Parameters:

eObject - The EObject whose containment chain is to be returned

topMostContainer - the container on which the search should stop

Returns:

a stack containing all the containers of eObject recursively up to topMostContainer (not included)

printDependencies

public java.lang.String printDependencies(org.eclipse.sirius.diagram.DEdge edge)

Returns a String of all EClassifiers in the target metamodel, on which some EClass in the source metamodel depends. EClassifiers are separated by a comma

Parameters:

edge -

Returns:

String representation of the dependencies

getEAllClassifiers

public static java.util.List<EClassifier> getEAllClassifiers(EPackage ePackage)

Gets all EClassifiers inside an EPackage recursively.

Parameters:

ePackage -

Returns:

a List containing the EClassfiers

getCorrespondingMetamodel

public Metamodel getCorrespondingMetamodel(EPackage mainPackage,
                                           ModularReferenceStructure mrs)

metamodelAlreadyExists

public boolean metamodelAlreadyExists(EPackage mainPackage,
                                      ModularReferenceStructure mrs)

hideTransitiveEdges

public void hideTransitiveEdges(org.eclipse.sirius.diagram.DSemanticDiagram diagram,
                                boolean excludeCyclicalDependencies)

Hides all edges in the diagram that are transitive. An edge is considered transitive if there exists another path from its source to its target

Parameters:

diagram - the MRS diagram

excludeCyclicalDependencies - if true, then edges that are part of cycles will not be hidden regardless of their being transitive or not
