    • getUnderlyingCollection

      protected Set<E> getUnderlyingCollection()
      Description copied from class: ImmutableAbstractCollection

      Overrides:
      getUnderlyingCollection in class ImmutableAbstractSet<E>
      Returns:
      the underlying collection of this immutable collection.

    • toSet

      public final Set<E> toSet()
      Description copied from interface: ImmutableSet
      Returns a modifiable copy of this immutable set.
      Returns:
      a modifiable copy of this immutable set.

    • toString

      public final String toString()
      Description copied from interface: ImmutableSet
      Force to redefine toString.
      Specified by:
      toString in interface ImmutableSet<E>
      Overrides:
      toString in class Object
      Returns:
      String; a description of this immutable set
