BooleanSets

public static class BooleanSets.EmptySet
extends BooleanCollections.EmptyCollection
implements BooleanSet, 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 Details

remove

public boolean remove(boolean ok)

Description copied from interface: BooleanSet

Removes an element from this set.

Specified by:

remove in interface BooleanSet

See Also:

• Collection.remove(Object)

clone

public Object clone()

equals

public boolean equals(Object o)

Specified by:

equals in interface Collection<Boolean>

Specified by:

equals in interface Set<Boolean>

Overrides:

equals in class BooleanCollections.EmptyCollection

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().

Specified by:

rem in interface BooleanCollection

Specified by:

rem in interface BooleanSet

Overrides:

rem in class AbstractBooleanCollection
