public static class BooleanSets.EmptySet

      public boolean remove​(boolean ok)
      Description copied from interface: BooleanSet
      Removes an element from this set.

    • rem

      @Deprecated public boolean rem​(boolean k)
      Deprecated.
      Description copied from class: AbstractBooleanCollection
      Removes a single instance of the specified element from this collection, if it is present (optional operation).

      Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().
