BooleanSets

public static class BooleanSets.EmptySet
extends BooleanCollections.EmptyCollection
implements BooleanSet, 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(boolean ok)

Description copied from interface: BooleanSet

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 BooleanSet

Collection.remove(Object)

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Collection<java.lang.Boolean>

Specified by:

equals in interface java.util.Set<java.lang.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().

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

rem in interface BooleanCollection

rem in interface BooleanSet
