For automation interface information about the Multiplicity property (Multiplicity Text through the automation interface), see the automation interface topic for a Ternary Role in the Related Topics.

This property specifies the multiplicity of a Ternary Role, from the Ternary Association to the Class, Data Type, Interface or Signal.

The multiplicity can be set to:

By default, the Multiplicity is set to Only One.

This property specifies that the Ternary Association can be associated with no items or one item. On the Class Diagram this multiplicity is shown as follows:

This property specifies that the Ternary Association can be associated with any number of items, including no items. On the Class Diagram this multiplicity is shown as follows:

This property specifies that the Ternary Association can be associated with one (and only one) item. On the Class Diagram this multiplicity is shown as follows:

This property specifies that the Ternary Association can be associated with any number of items, except none. On the Class Diagram this multiplicity is shown as follows:

This property specifies that the multiplicity is to be decided. On the Class Diagram this multiplicity is shown as follows:

This property specifies that the Ternary Association can be associated with only a specific number of items. On the Class Diagram this multiplicity is shown as follows (in this example, 63):

Note that when you select User Defined, an additional box appear for you to specify a value.
