public interface CwmUnionClass
extends RefClass

Union class proxy interface. The Union class represents programming language unions and similarly structured data types. Because of the diversity of union semantics found across software systems, the Union and UnionMember classes are likely candidates for specialization to better capture union semantics in specific language extension packages. A discriminated Union has a collection of UnionMembers that determine the sets of contents that the Union may contain. Such Unions have an attribute called the discriminator that identifies the memberCase value of the UnionMember that the Union currently contains. The discriminator is found via the UnionDiscriminator association to StructuralFeature. The discriminator may be embedded within UnionMembers or may be located outside the discriminator. If it is located within UnionMembers, the discriminator should occur in every UnionMember at the same location (often, the first). Undiscriminated unions (for example, a C language union) are also supported, but have an empty discriminator reference, and the memberCase attribute of the UnionMembers it contains is ignored. Undiscriminated Unions are often used to represent alternate views of a single physical storage area. A fine degree of control over this aspect of Unions may be obtained by creating a class that derives from both UnionMember and FixedOffsetField (in the CWM Record package) and setting the offset attribute instances of that class accordingly.

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

createCwmUnion

CwmUnion createCwmUnion()

The default factory operation used to create an instance object.

Returns:

The created instance object.

createCwmUnion

CwmUnion createCwmUnion(String name,
                        VisibilityKind visibility,
                        boolean isAbstract)

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.

isAbstract - An abstract Classifier is not instantiable.

Returns:

The created instance object.
