public static class ShortSets.EmptySet
extends ShortCollections.EmptyCollection
implements ShortSet, Serializable, 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(short ok)

Description copied from interface: ShortSet

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.

Specified by:

remove in interface ShortSet

clone

Overrides:

equals

public boolean equals(Object o)

Specified by:

Specified by:

Overrides:

rem

@Deprecated
public boolean rem(short k)

Deprecated.

Description copied from class: AbstractShortCollection

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.

Specified by:

rem in interface ShortCollection

Specified by:

rem in interface ShortSet

Overrides:

rem in class AbstractShortCollection
