@CheckForNull
public static Slot getSlot(InstanceSpecification instance,
                           Property property,
                           boolean createSlotIfNotExists,
                           boolean createDefaultValue)

Returns existing of creates a new Slot for the given property

Parameters:

instance - instance specification

property - feature

createSlotIfNotExists - create a new slot if needed

createDefaultValue - fill slot value from property default value

Returns:

slot

getNestedSlot

@CheckForNull
public static Slot getNestedSlot(InstanceSpecification instanceSpecification,
                                 Property property,
                                 java.util.List<Property> path,
                                 int index)

createSlotsForDefaultValues

public static void createSlotsForDefaultValues(InstanceSpecification instance,
                                               Classifier classifier,
                                               boolean createAll)

Creates slots for properties of given classifier.

Parameters:

instance - instance to create slots for

classifier - classifier of the instance

createAll - true, if creates slots for all properties (do not check multiplicity). false, to create slots for properties with mandatory value, i.e. with lower multiplicity >= 1.

createSlotsForDefaultValues

public static void createSlotsForDefaultValues(InstanceSpecification instance,
                                               boolean createAll)

Creates slots for properties of all assigned classifiers to instance.

Parameters:

instance - instance

createAll - true, if creates slots for all properties (do not check multiplicity). false, to create slots for properties with mandatory value, i.e. with lower multiplicity >= 1.

isInstanceSpecificationCompatibleWithType

public static boolean isInstanceSpecificationCompatibleWithType(Classifier type,
                                                                InstanceSpecification instance,
                                                                boolean checkInherited)

Checks if given instance specification is compatible with given Type. Instance is compatible if its classifiers are compatible with given type.

Parameters:

type - instance compatibility will be checked against this type

instance - instance to check for compatible classifiers

checkInherited - if set to true, then classifiers derived/realized from given type will be treated as compatible.

Returns:

true if instance is compatible with given type

getLinksBetweenInstances

public static java.util.Collection<InstanceSpecification> getLinksBetweenInstances(InstanceSpecification client,
                                                                                   InstanceSpecification supplier)

Returns links found between client and supplier instances

Parameters:

client - instance

supplier - instance

Returns:

links

isConnectedToClient

private static boolean isConnectedToClient(InstanceSpecification client,
                                           Element link)

collectInstancesOf

public static java.util.Collection<InstanceSpecification> collectInstancesOf(Classifier classifier,
                                                                             java.util.Collection<InstanceSpecification> instances)

Collect all instances of given classifier. Instances of derived classifiers are also collected.

Parameters:

classifier - classifier

Returns:

the passed in collection, appended with instances of the classifier and its' subtypes

getValueBySlot

@CheckForNull
public static java.lang.Object getValueBySlot(@CheckForNull
                                              Slot slot)

Retrieves values of slots as object, not as ValueSpecifications. Takes into account multiplicity of slot's defining feature. Collection is returned if slot multiplicity is many.

Parameters:

slot - slot

Returns:

value of slot

setClassifiers

public static void setClassifiers(InstanceSpecification instance,
                                  @CheckForNull
                                  java.util.Collection<? extends Classifier> classifiers,
                                  boolean createSlots)
