Method Detail

checkIdentity

public static boolean checkIdentity(EObject i1,
                                    EObject i2)

Checks for two PCM model elements whether they are the same, i.e. whether they have the same ID. The model elements have to be derived from Identifier. Note that two systems might use the same assembly contexts and components, but still are two different systems. If one of the Identifiers in null, false is returned.

Parameters:

i1 - One Identifier

i2 - Another Identifier

Returns:

true if i1.getId().equals(i2.getId()), false otherwise

contains

public static boolean contains(Collection<? extends EObject> coll,
                               EObject i)

Implements an identifier-based contains. Calls #checkIdentity(Identifier, Identifier) to compare the Identifier i with the contents of the collection.

Parameters:

coll -

i -

Returns:

true if there is an Identifier in coll with an id equal to i.getID().

retainAll

public static boolean retainAll(Collection<? extends de.uka.ipd.sdq.identifier.Identifier> collection,
                                Collection<? extends EObject> itemsToRetain)

saveToXMIFile

public static void saveToXMIFile(EObject modelToSave,
                                 URI fileName)

Save the given EObject to the file given by filename.

Parameters:

modelToSave - The EObject to save

fileName - The filename where to save.

loadFromXMIFile

public static EObject loadFromXMIFile(URI fileName,
                                      EPackage ePackage)

Copied From de.uka.ipd.sdq.pcmsolver.models.PCMInstance.

Parameters:

fileName - the filename specifying the file to load from

Returns:

The EObject loaded from the file

loadFromXMIFile

public static EObject loadFromXMIFile(URI uri,
                                      ResourceSet resourceSet,
                                      EPackage ePackage)

retrieveEntityByID

public static org.palladiosimulator.pcm.core.entity.Entity retrieveEntityByID(List<? extends EObject> entities,
                                                                              EObject object)

retrieveEntityByID

public static org.palladiosimulator.pcm.core.entity.Entity retrieveEntityByID(List<? extends org.palladiosimulator.pcm.core.entity.Entity> entities,
                                                                              String id)

indexOfByID

public static int indexOfByID(List<? extends org.palladiosimulator.pcm.core.entity.Entity> entities,
                              String id)

createEMFCandidates

public static Candidates createEMFCandidates(Collection<DSEIndividual> individuals)

getPassiveResources

public static List<org.palladiosimulator.pcm.repository.PassiveResource> getPassiveResources(List<org.palladiosimulator.pcm.repository.Repository> repositoryList)

getAllUsedAssemblyContexts

public static List<org.palladiosimulator.pcm.core.composition.AssemblyContext> getAllUsedAssemblyContexts(org.palladiosimulator.pcm.core.entity.ComposedProvidingRequiringEntity composite)

Recursively get all contained AssemblyContexts in one flat list.

getAllUsedAllocationContexts

public static List<org.palladiosimulator.pcm.allocation.AllocationContext> getAllUsedAllocationContexts(org.palladiosimulator.pcm.allocation.Allocation allocation)

loadFromXMIFile

public static EObject loadFromXMIFile(String fileName,
                                      EPackage ePackage)

Deprecated.
