Class UML 2.3::FunctionBehavior

Description:

A function behavior is an opaque behavior that does not access or modify any objects or other external data.

Direct Superclasses: OpaqueBehavior

Direct Subclasses:

Class Precedence List: FunctionBehavior, OpaqueBehavior, Behavior, Class, EncapsulatedClassifier, StructuredClassifier, BehavioredClassifier, Classifier, TemplateableElement, Type, PackageableElement, ParameterableElement, Namespace, RedefinableElement, NamedElement, Element

Properties:

body : String (0 *); -- source OpaqueBehavior
language : String (0 *); -- source OpaqueBehavior
context : BehavioredClassifier (0 1); -- source Behavior
isReentrant : Boolean (1 1); -- source Behavior
ownedParameter : Parameter (0 *); -- source Behavior

postcondition : Constraint (0 *); -- source Behavior
precondition : Constraint (0 *); -- source Behavior
redefinedBehavior : Behavior (0 *); -- source Behavior
specification : BehavioralFeature (0 1); -- source Behavior
extension : Extension (0 *); -- source Class

References the Extensions that specify additional properties of the metaclass. The property is derived from the extensions whose memberEnds are typed by the Class.
{readonly, derived}
Opposite: Extension.metaclass
The spec does not provide a function to compute this derived property!

Constraints:

Signature: types_of_parameters() : Boolean;
Description: The types of parameters are all data types, which may not nest anything but other datatypes.
The OCL used here is not normative.
Editor's notes: Is this an operator or a constraint?
Expression: true
Original: def: hasAllDataTypeAttributes(d : DataType) : Boolean = d.ownedAttribute->forAll(a | a.type.oclIsTypeOf(DataType) and hasAllDataTypeAttributes(a.type)) self.ownedParameters->forAll(p | p.type.notEmpty() and p.oclIsTypeOf(DataType) and hasAllDataTypeAttributes(p))

Signature: one_output_parameter() : Boolean;
Description: A function behavior has at least one output parameter.
Expression: self.ownedParameter-> select(p | p.direction=#out or p.direction=#inout or p.direction=#return)->size() >= 1

Operations:

No additional operations.
