getConstrainedElements

public List<EModelElement> getConstrainedElements(Constraint constraint)

Description copied from interface: UMLReflection

Obtains the list of element constraint by a constraint, as a list of EObjects. This list is modifiable, but only after an unsafe cast to establish a lower type bound. Therefore the UMLReflection.addConstrainedElement(CT, EObject) method should be used instead.

Specified by:

getConstrainedElements in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

constraint - a constraint

Returns:

its constrained elements

addConstrainedElement

public void addConstrainedElement(Constraint constraint,
                                  EObject constrainedElement)

Description copied from interface: UMLReflection

Adds a constrainedElement to a constraint.

Specified by:

addConstrainedElement in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

constraint - the constraint to receive

constrainedElement - the constrained element

getQualifiers

public List<EStructuralFeature> getQualifiers(EStructuralFeature property)

Gets the qualifiers of an association end. By default, it is assumed that properties never have qualifiers because Ecore does not directly support this concept.

Specified by:

getQualifiers in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

property - a property of the model class

Returns:

an empty list, by default

getCommonSuperType

public EClassifier getCommonSuperType(EClassifier type1,
                                      EClassifier type2)

Get the common supertype of two types.

Specified by:

getCommonSuperType in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

type1 -

type2 -

Returns:

the common supertype

getRelationship

public int getRelationship(EClassifier type1,
                           EClassifier type2)

Computes the relationship between two types.

Specified by:

getRelationship in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

type1 - a type

type2 - another type

Returns:

either UMLReflection.UNRELATED_TYPE, UMLReflection.STRICT_SUBTYPE, UMLReflection.STRICT_SUPERTYPE, or UMLReflection.SAME_TYPE according to the relationship between the types

getOCLCollectionType

public EClassifier getOCLCollectionType(EClassifier type,
                                        boolean isOrdered,
                                        boolean isUnique)

Obtains the appropriate OCL collection type for an EClassifier, according to the collection's orderedness and uniqueness. The mapping is as follows:

• ordered, unique: ordered set type
• ordered, non-unique: sequence type
• non-ordered, unique: set type
• non-ordered, non-unique: bag type

Note that the collection's element type is mapped to an OCL primitive type where possible.

Parameters:

type - the type to get the corresponding OCL collection type for

isOrdered - whether the OCL type should be ordered

isUnique - whether the OCL type should be unique

Returns:

the corresponding OCL type

getOCLType(EClassifier)

isAncestor

public static boolean isAncestor(EObject ancestor,
                                 EObject descendent)

Queries whether a prospective ancestor really is a container (recursively) of the specified descendent. This utility is like the similar EcoreUtil operation, except that it does not require the arguments to be InternalEObjects.

Parameters:

ancestor - a prospective ancestor element

descendent - a prospective descendent element

Returns:

true if the ancestor contains (recursively) the descendent

setName

public void setName(TypedElement<EClassifier> element,
                    String name)

Description copied from interface: UMLReflection

Sets the name of the specified typed element.

Specified by:

setName in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

element - a typed element

name - the type element's name

See Also:

TypedElement.getName()

setType

public void setType(TypedElement<EClassifier> element,
                    EClassifier type)

Description copied from interface: UMLReflection

Sets the type of the specified typed element.

Specified by:

setType in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

element - a typed element

type - the type element's type

See Also:

TypedElement.getType()

setIsStatic

public boolean setIsStatic(Object feature,
                           boolean isStatic)

Description copied from interface: UMLReflection

Sets a property or operation static (applies to a classifier rather than to its instances).
If the UML meta-model implementation (e.g. Ecore) does not support static features, or if the feature is not a feature, this mertghod does nothing and returns false.

Specified by:

setIsStatic in interface UMLReflection<EPackage,EClassifier,EOperation,EStructuralFeature,EEnumLiteral,EParameter,EObject,CallOperationAction,SendSignalAction,Constraint>

Parameters:

feature - an operation or a property

isStatic - whether it is to be static

Returns:

whether isStatic was successfully applied
