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.

ElementProperties:
extension :
Extension (0 *); -- source
Class isAbstract : Boolean (1 1); -- source
Class isActive : Boolean (1 1); -- source
Class Determines whether an object specified by this class is active or not.
If true, then the owning class is referred to as an active class. If false,
then such a class is referred to as a passive class.
Default value: FALSE

such as other associations or constraints.

ElementConstraints:
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.
