Method Detail

areEqual

public static boolean areEqual(VControl left,
                               org.eclipse.emf.ecore.EObject leftDomainModel,
                               VControl right,
                               org.eclipse.emf.ecore.EObject rightDomainModel)

Compares to VControls. This is just a convenience method which delegates to areEqual(VDomainModelReference,EObject, VDomainModelReference,EObject).

Parameters:

left - the first VControl to compare

leftDomainModel - The domain model of the left VControl

right - the second VControl to compare

rightDomainModel - The domain model of the right VControl

Returns:

true if all values of the VDomainModelReferences are equal

areEqual

public static boolean areEqual(VDomainModelReference left,
                               org.eclipse.emf.ecore.EObject leftDomainModel,
                               VDomainModelReference right,
                               org.eclipse.emf.ecore.EObject rightDomainModel)

Compares to VDomainModelReferences by comparing all values.

Parameters:

left - the first VDomainModelReference

leftDomainModel - The domain model of the left VControl

right - the second VDomainModelReference

rightDomainModel - The domain model of the right VControl

Returns:

true if all values of the VDomainModelReferences are equal

areValuesEqual

public static boolean areValuesEqual(Object leftValue,
                                     org.eclipse.emf.ecore.EStructuralFeature leftStructuralFeature,
                                     Object rightValue,
                                     org.eclipse.emf.ecore.EStructuralFeature rightStructuralFeature)

Compares two EStructuralFeatures and their values. If both are null, they are equal. For a single reference, the referenced EObjects are compare (equals). For a "many" references, a list entries are compared.

Parameters:

leftValue - the value of the left EStructuralFeature

leftStructuralFeature - the left EStructuralFeature

rightValue - the value of the right EStructuralFeature

rightStructuralFeature - the right EStructuralFeature

Returns:

whether the values are equal
