argument

A specific value corresponding to a parameter.

See also binding, parameter, substitutability principle.

Semantics

A run-time instance of a parameterized element, such as an operation or an action, has a list of argument values, each of which is a value whose type must be consistent with the declared type of the matching parameter. A value is consistent if its class or data type is the same or a descendant of the declared type of the parameter. By the substitutability principle, a value of a descendant may be used anywhere an ancestor type is declared.

An occurrence of a broadcast action, a call action, or a send action requires arguments for the parameters, unless the signal or operation lacks attributes or parameters.
