Class UML 2.3::AssociationClass

Description:

A model element that has both association and class properties. An AssociationClass can be seen as an association that also has class properties, or as a class that also has association properties. It not only connects a set of classifiers but also defines a set of features that belong to the relationship itself and not to any of the classifiers.

Direct Superclasses: Class, Association

Direct Subclasses:

Constraints:

Signature: disjoint_attributes_ends() : Boolean;
Description: The owned attributes and owned ends of an AssociationClass are disjoint
Expression: ownedAttribute->intersection(ownedEnd)->isEmpty()

Signature: cannot_be_defined() : Boolean;
Description: An AssociationClass cannot be defined between itself and something else.
The OCL used here is not normative.
Editor's notes: (1) allParents not allparents,(2) -> not > (3) Need a forAll to deal with collection of Boolean???
Expression: self.endType->excludes(self) and self.endType->collect(et|et.allParents()->excludes(self))->forAll(x|x)
Original: self.endType->excludes(self) and self.endType->collect(et|et.allparents()->excludes(self))

Operations:

No additional operations.
