Method Summary

Modifier and Type	Method and Description
boolean	evaluate(Condition condition, org.eclipse.emf.ecore.EObject domainModel) Evaluates the given condition using the provided domain model.
boolean	evaluateChangedValues(Condition condition, org.eclipse.emf.ecore.EObject domainModel, Map<org.eclipse.emf.ecore.EStructuralFeature.Setting,Object> possibleNewValues) Evaluates whether the given condition using the provided domain model will change if a specific setting will be set to a specific value.
Set<UniqueSetting>	getConditionSettings(Condition condition, org.eclipse.emf.ecore.EObject domainModel) Returns the conditionSetting for a condition and the corresponding domain model.
Set<VDomainModelReference>	getDomainModelReferences(Condition condition) The Set of DomainModelReferences this condition needs to evaluate.

Method Detail

getConditionSettings

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,
                              Map<org.eclipse.emf.ecore.EStructuralFeature.Setting,Object> possibleNewValues)

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

Set<VDomainModelReference> getDomainModelReferences(Condition condition)

The Set of DomainModelReferences this condition needs to evaluate.

Parameters:

condition - The condition to retrieve the VDomainModelReferences for

Returns:

The Set of DomainModelReferences. The set cannot be null.
