public interface CwmUnionMember
extends CwmAttribute

UnionMember object instance 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 Summary

CwmExpression	getMemberCase() Returns the value of attribute memberCase.
boolean	isDefault() Returns the value of attribute isDefault.
void	setDefault(boolean newValue) Sets the value of isDefault attribute.
void	setMemberCase(CwmExpression newValue) Sets the value of memberCase attribute.

Method Detail

getMemberCase

CwmExpression getMemberCase()

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

Returns:

Value of attribute memberCase.

setMemberCase

void setMemberCase(CwmExpression newValue)

Sets the value of memberCase attribute. See getMemberCase() for description on the attribute.

Parameters:

newValue - New value to be set.

isDefault

boolean isDefault()

Returns the value of attribute 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:

Value of attribute isDefault.

setDefault

void setDefault(boolean newValue)

Sets the value of isDefault attribute. See isDefault() for description on the attribute.

Parameters:

newValue - New value to be set.
