    Modifier and Type Method Description
    static java.util.function.Predicate<? super Diff> ofKind​(DifferenceKind... kind)
    This predicate can be used to check whether a particular diff is of the given kind.
    static java.util.function.Predicate<Diff> onFeature​(EStructuralFeature feature)
    Accept only diffs that inherit either AttributeChange, ReferenceChange, or FeatureMapChange that concern the given feature.
    static java.util.function.Predicate<Diff> possiblyConflictingWith​(Diff diff)
    Predicate builder for diffs that can conflict with the given diff.
    static java.util.function.Predicate<Diff> valueMatches​(IEqualityHelper helper, java.lang.Object value)
    Accept only diffs whose value matches the given value.

    • possiblyConflictingWith

      public static java.util.function.Predicate<Diff> possiblyConflictingWith​(Diff diff)
      Predicate builder for diffs that can conflict with the given diff.
      Parameters:
      diff - The diff
      Returns:
      A predicate that accepts diffs that might conflict with the given diff.

    • ofKind

      public static java.util.function.Predicate<? super Diff> ofKind​(DifferenceKind... kind)
      This predicate can be used to check whether a particular diff is of the given kind. This is mainly used to differentiate additions from deletions.
      Parameters:
      kind - The kind we expect this diff to have.
      Returns:
      The created predicate.

    • onFeature

      public static java.util.function.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 java.util.function.Predicate<Diff> valueMatches​(IEqualityHelper helper, java.lang.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.
