BooleanSets

public static class BooleanSets.Singleton
extends AbstractBooleanSet
implements java.io.Serializable, java.lang.Cloneable

Method Detail

contains

public boolean contains(boolean k)

Description copied from class: AbstractBooleanCollection

Returns true if this collection contains the specified element.

This implementation iterates over the elements in the collection, looking for the specified element.

Specified by:

contains in interface BooleanCollection

Overrides:

contains in class AbstractBooleanCollection

See Also:

Collection.contains(Object)

remove

public boolean remove(boolean k)

Description copied from class: AbstractBooleanSet

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. Delegates to the type-specific rem() method implemented by type-specific abstract Collection superclass.

Specified by:

remove in interface BooleanSet

Overrides:

remove in class AbstractBooleanSet

See Also:

Collection.remove(Object)

iterator

public BooleanListIterator iterator()

Description copied from interface: BooleanCollection

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface BooleanCollection

Specified by:

iterator in interface BooleanIterable

Specified by:

iterator in interface BooleanSet

Specified by:

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

Specified by:

iterator in interface java.lang.Iterable<java.lang.Boolean>

Specified by:

iterator in interface java.util.Set<java.lang.Boolean>

Specified by:

iterator in class AbstractBooleanSet

Returns:

a type-specific iterator on the elements of this collection.

See Also:

Iterable.iterator()

size

public int size()

Specified by:

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

Specified by:

size in interface java.util.Set<java.lang.Boolean>

Specified by:

size in class java.util.AbstractCollection<java.lang.Boolean>

addAll

public boolean addAll(java.util.Collection<? extends java.lang.Boolean> c)

Specified by:

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

Specified by:

addAll in interface java.util.Set<java.lang.Boolean>

Overrides:

addAll in class java.util.AbstractCollection<java.lang.Boolean>

removeAll

public boolean removeAll(java.util.Collection<?> c)

Specified by:

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

Specified by:

removeAll in interface java.util.Set<java.lang.Boolean>

Overrides:

removeAll in class java.util.AbstractCollection<java.lang.Boolean>

retainAll

public boolean retainAll(java.util.Collection<?> c)

Specified by:

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

Specified by:

retainAll in interface java.util.Set<java.lang.Boolean>

Overrides:

retainAll in class java.util.AbstractCollection<java.lang.Boolean>

addAll

public boolean addAll(BooleanCollection c)

Description copied from interface: BooleanCollection

Adds all elements of the given type-specific collection to this collection.

Specified by:

addAll in interface BooleanCollection

Overrides:

addAll in class AbstractBooleanCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.addAll(Collection)

removeAll

public boolean removeAll(BooleanCollection c)

Description copied from interface: BooleanCollection

Remove from this collection all elements in the given type-specific collection.

Specified by:

removeAll in interface BooleanCollection

Overrides:

removeAll in class AbstractBooleanCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.removeAll(Collection)

retainAll

public boolean retainAll(BooleanCollection c)

Description copied from interface: BooleanCollection

Retains in this collection only elements from the given type-specific collection.

Specified by:

retainAll in interface BooleanCollection

Overrides:

retainAll in class AbstractBooleanCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

Collection.retainAll(Collection)

clone
