      Checks if the trait was added.
      Parameters:
      trait - Trait to check.

      Returns true if the trait was added.

    • isTraitRemoved

      public boolean isTraitRemoved(ShapeId trait)
      Checks if the trait was removed.
      Parameters:
      trait - Trait to check.

    • isTraitInBoth

      public boolean isTraitInBoth(ShapeId trait)
      Checks if the given trait is in the old shape and new shape.
      Parameters:
      trait - Trait to check.

    • getChangedTrait

      public <T extends Trait> Optional<Pair<T,T>> getChangedTrait(Class<T> traitType)
      Gets a changed trait of a specific type.
      Type Parameters:
      T - Type of trait to find.
      Parameters:
      traitType - Type of trait to find.
      Returns:
      Returns the optionally found old and new typed trait values.

    • getTraitDifferences

      public Map<ShapeId,Pair<Trait,Trait>> getTraitDifferences()
      Gets the trait differences between the old and new shape.

      The returned map is a mapping of a trait name to a pair in which the left side of the pair contains the nullable old trait value, and the right side of the pair contains the nullable new trait value. The left side will be null if the trait was added, the right side will be null if the trait was removed, and both traits will be present if the trait changed.

      Returns:
      Returns a map of each changed trait name to a pair of the old and new trait values.
