Interface CwmUnionMemberClass

All Superinterfaces:

RefBaseObject, RefClass, RefFeatured

All Known Implementing Classes:

CwmUnionMemberClass$Hib

public interface CwmUnionMemberClass
extends RefClass

UnionMember class proxy interface. UnionMembers are described as features of a Union and each represents one of the members of a Union. Note, however, that multiple case values can map to a single UnionMember. If isDefault is true, the union member is the default member. UnionMember instances are allowed to have a memberCase and be the default case. UnionMember instances often represent structured storage areas. A particular UnionMember may be associated with a Classifier that describes its internal structure via the StructuralFeatureType association (defined in the ObjectModel::Core package). For example, the Record::Group class, itself a Classifier, can be used as the type of a UnionMember in a manner completely analogous to how it is used to describe the type of a structured field (see the instance diagrams in the Record metamodel chapter for details).

Note: This type should not be subclassed, implemented or directly instantiated by clients. It is generated from a MOF metamodel and implemented by Enki or MDR.

Method Detail

createCwmUnionMember

CwmUnionMember createCwmUnionMember()

The default factory operation used to create an instance object.

Returns:

The created instance object.

createCwmUnionMember

CwmUnionMember createCwmUnionMember(String name,
                                    VisibilityKind visibility,
                                    ScopeKind ownerScope,

                                    CwmMultiplicity multiplicity,

                                    boolean isDefault)

Creates an instance object having attributes initialized by the passed values.

Parameters:

name - An identifier for the ModelElement within its containing Namespace.

visibility - Specifies extent of the visibility of the ModelElement within its owning Namespace.

ownerScope - Specifies whether the Feature appears in every instance of the Classifier or whether it appears only once for the entire Classifier.

changeability - Specifies whether the value may be modified after the object is created.

multiplicity - The possible number of data values for the feature that may be held by an instance. The cardinality of the set of values is an implicit part of the feature. In the common case in which the multiplicity is 1..1, then the feature is a scalar (i.e., it holds exactly one value).

ordering - Specifies whether the set of instances is ordered. The ordering must be determined and maintained by Operations that add values to the feature. This property is only relevant if the multiplicity is greater than one.

targetScope - Specifies whether the targets are ordinary Instances or are Classifiers.

initialValue - An Expression specifying the value of the attribute upon initialization. It is meant to be evaluated at the time the object is initialized. (Note that an explicit constructor may supersede an initial value.)

memberCase - Contains the value of the Union?s discriminator for this UnionMember.

isDefault - Indicates if this UnionMember is the default member of the Union (implying that when unstated, the Union?s discriminator would assume this instance?s memberCase value).

Returns:

The created instance object.
