Documentation

Definition

The cardinality of a node specifies whether

• a single instance or
• a table with instances

of an object can or must exist at runtime.

The following values are possible:

• 1..1 : The node contains exactly one instance that must always be instantiated
• 0..1 : The node contains exactly one instance that does not have to be instantiated
• 1..n : The node can contain multiple instances and at least one of them must be instantiated
• 0..n : The node can contain multiple instances and none of them must be instantiated

The default is 1..1.

Use

Dependencies

The value of the cardinality affects the possible values of the selection cardinality (property "Selection"): If the value for the cardinality does not require the instantiation of an instance, the selection cardinality cannot have a value that requires at least one instantiation.
