      The created predicate.

    • onFeature

      public static Predicate<Diff> onFeature(EStructuralFeature feature)
      Accept only diffs that inherit either AttributeChange, ReferenceChange, or FeatureMapChange that concern the given feature.
      Parameters:
      feature - Feature to deal with
      Returns:
      a new predicate that accepts diffs that concern the given feature.

    • valueMatches

      public static Predicate<Diff> valueMatches(IEqualityHelper helper, Object value)
      Accept only diffs whose value matches the given value.
      Parameters:
      helper - The helper to match values
      value - The value to match
      Returns:
      The created predicate.
