Enum Class Cardinality

java.lang.Object
java.lang.Enum<Cardinality>
com.ptc.windchill.annotations.metadata.Cardinality
All Implemented Interfaces:
Serializable, Comparable<Cardinality>, Constable
public enum Cardinality extends Enum<Cardinality>
Specifies the legitimate number of occurrences for the associated role. This property is mostly obsolete, as cardinality is largely irrelevant to the persistence framework.

Rose conversion note: Corresponds to Association Specification -> Role A/B Detail -> Multiplicity.

Supported API: true
