Interface FeatureAwareComparator<T>

  • Type Parameters:
    T - The type of the objects comparable with this comparator
    All Known Implementing Classes:
    LocalizedEnumeratorComparator
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
public interface FeatureAwareComparator<T>
    Defines a comparator which knows about the feature that the compared values are stored in. This allows to use knowledge of the feature for the comparison.

    • Method Detail

      • compare

        int compare​(org.eclipse.emf.ecore.EStructuralFeature feature,
            T leftValue,
            T rightValue)
        Compares two values of the given feature.
        Parameters:
        feature - The EStructuralFeature containing the values
        leftValue - Left value
        rightValue - Right Value
        Returns:
        a negative number if the left value is less than the right value; the value 0 if the left value is equal to the right value; a positive number if the left value is greater than the right value. Thereby, null input values are treated as bigger than any other non-null value
