Detailed Description

FeatureConstraint (from FeatureModeling)

Generalizations
EAElement (from Elements)

Description
Captures a constraint on the containing feature model's configuration which is too complex to be expressed by way of a FeatureLink. In general, all constraints that can be expressed by a FeatureLink can also be expressed by a FeatureConstraint, but not vice versa.

Attributes
criterion : String [1]
The actual constraint. This is a logic expression in VSL like the criterion of a ConfigurationDecision. For the constraint to be met this expression always has to evaluate to true.
For example, to express a mutual exclusion of two features, use the expression "! (Radar & RainSensor)". However, note that this particular constraint could also be formulated as a FeatureLink with type "excludes".
