All Implemented Interfaces:: java.io.Serializable, Poster

public class CrNWayAgg
extends CrUML
extends CrUML

A critic to check that no end of a 3-way (or more) association is an aggregation.

This is the third well-formedness rule for associations in the UML 1.3 standard (see section 2.5.3 of the standard).

Well-formedness rule [3] for Association. See page 52 of UML 1.4 Semantics. OMG document UML 1.4.2 formal/04-07-02. Note. This only applies to 3-way or more associations. There is a separate critic (see CrMultipleAgg) which deals with 2-way assocations.

See ArgoUML User Manual: Two Aggregate ends (roles) in binary Association

Constructor Detail

CrNWayAgg

public CrNWayAgg()

Constructor for the critic.

Sets up the resource name, which will allow headline and description to found for the current locale. Provides a design issue category (CONTAINMENT), a knowledge type (SEMANTICS) and add triggers for "connection" and "end_aggregation".

Method Detail

predicate2

public boolean predicate2(java.lang.Object dm,
                          Designer dsgr)

The trigger for the critic.

Check that the number of ends more than two, otherwise this should be handled by the critic for 2-way assocations (see CrMultipleAgg).

We do not handle association roles, which are a subclass of association. An association role should be fine, if its parent is OK, since it must be more tightly constrained than its parent.

Note. ArgoUML does not currently have a constructor to check that an association role is more tightly constrained than its parent.

Then loop through the ends, looking for aggregate ends. Note that we look for aggregation explicitly, rather than just absence of "no aggregation", so we don't trigger if the aggregation is just undefined.

Overrides:: predicate2 in class CrUML

Parameters:: dm - the Object to be checked against the critic.; dsgr - the Designer creating the model. Not used, this is for future development of ArgoUML.
Returns:: PROBLEM_FOUND if the critic is triggered, otherwise NO_PROBLEM.

getCriticizedDesignMaterials

public java.util.Set<java.lang.Object> getCriticizedDesignMaterials()

Description copied from class: Critic

Get the design materials to be criticized by this critic

Overrides:: getCriticizedDesignMaterials in class Critic

Returns:: the design materials
