Method Detail

getConditionType

org.eclipse.emf.ecore.EClass getConditionType()

The EClass this ConditionService is implemented for.

Returns:

The EClass of the Condition

getConditionSettings

java.util.Set<UniqueSetting> getConditionSettings(T condition,
                                                  org.eclipse.emf.ecore.EObject domainModel)

The set of UniqueSetting that are relevant for the provided condition and domain model.

Parameters:

condition - The Condition to get the UniqueSettings for

domainModel - The EObject to use for retrieving

Returns:

The Set of UniqueSettings. This Set must not be null.

evaluate

boolean evaluate(T condition,
                 org.eclipse.emf.ecore.EObject domainModel)

Evaluates the given condition.

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(T condition,
                              org.eclipse.emf.ecore.EObject domainModel,

Evaluates the given condition.

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

java.util.Set<VDomainModelReference> getDomainModelReferences(T condition)

The Set of VDomainModelReference that are relevant for the condition.

Parameters:

condition - The Condition to retrieve the VDMRs for

Returns:

The Set of VDomainModelReferences. This Set must not be null.
