ElementConstraints:
Signature: type_and_ordering() : Boolean;
Description: The type and ordering of the result output pin of a read-variable action
are the same as the type and ordering of the variable.
Expression: self.result.type =self.variable.type
and self.result.ordering = self.variable.ordering
Signature: compatible_multiplicity() : Boolean;
Description: The multiplicity of the variable must be compatible with the multiplicity
of the output pin.
The OCL used here is not normative.Editor's notes: No multiplicity
Expression: self.variable.compatibleWith(self.result)
Original: self.variable.multiplicity.compatibleWith(self.result.multiplicity)
Operations:
No additional operations.
