In-Depth Information
Figure 5.3 presents our constraint metamodel. The main
new concepts and attributes added to our feature metamodel
are the following:
-
GroupConstraint
. It allows us to create constraints
including group features;
-
Constraint
. It allows us to create constraints including
solitary or grouped features;
-
fineMin
and
fineMax
attributes. They allow us to relate
the cardinality property to constraints;
-
OCLExpression
. It represents the structural dependency
property of constraints;
-
Metaconcept
. It represents metaconcepts related to
constraints.
