AssociationRole

public class Association

extends GeneralizableElement

An association defines a semantic relationship between classifiers; the instances of an association are a set of tuples relating instances of the classifiers. Each tuple value may appear at most once.

In the metamodel an Association is a declaration of a semantic relationship between Classifiers, such as Classes. An Association has at least two AssociationEnds. Each end is connected to a Classifier; the same Classifier may be connected to more than one AssociationEnds in the same Association. The Association represents a set of connections among instances of the Classifiers. An instance of an Association is a Link, which is a tuple of Instances drawn from the corresponding Classifiers.
