Class UML 2.4.1::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.

ClassifierSpecifies each feature defined in the classifier. Note that there may be
members of the Classifier that are of the type Feature but are not included
in this association, e.g. inherited features.

NamedElementA name which allows the NamedElement to be identified within a hierarchy
of nested Namespaces. It is constructed from the names of the containing
namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.

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.
