      • getConditionSettings

        java.util.Set<UniqueSetting> getConditionSettings​(Condition condition,
                                                  org.eclipse.emf.ecore.EObject domainModel)
        Returns the conditionSetting for a condition and the corresponding domain model.
        Parameters:
        condition - The condition to get the settings for
        domainModel - The domain model this condition applies to
        Returns:
        The Set of Settings. This set cannot be null.

      • evaluate

        boolean evaluate​(Condition condition,
                 org.eclipse.emf.ecore.EObject domainModel)
        Evaluates the given condition using the provided domain model.
        Parameters:
        condition - The condition to evaluate.
        domainModel - The root domain object of this condition.
        Returns:
        true, if the condition matches, false otherwise

      • evaluateChangedValues

        boolean evaluateChangedValues​(Condition condition,
                              org.eclipse.emf.ecore.EObject domainModel,

        Evaluates whether the given condition using the provided domain model will change if a specific setting will be set to a specific value.
        Parameters:
        condition - The condition to evaluate.
        domainModel - The root domain object of this condition.
        possibleNewValues - the new value that should be compared against the expected value of the condition
        Returns:
        true, if the condition matches, false otherwise

      • getDomainModelReferences

        Parameters:
        condition - The condition to retrieve the VDomainModelReferences for
        Returns:
        The Set of DomainModelReferences. The set cannot be null.
