    public static class FloatSets.EmptySet
    extends FloatCollections.EmptyCollection
    implements FloatSet, java.io.Serializable, java.lang.Cloneable
    An immutable class representing the empty set and implementing a type-specific set interface.

    This class may be useful to implement your own in case you subclass a type-specific set.

    • Method Detail

      • remove

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

        Note that the corresponding method of a type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

      • rem

        @Deprecated
        public boolean rem​(float k)
        Deprecated.
        Description copied from class: AbstractFloatCollection
        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().

        This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.
