Method Detail

add

public boolean add(Object k)

Specified by:

add in interface Set

Overrides:

add in class AbstractObjectCollection

contains

public boolean contains(Object k)

Specified by:

contains in interface Set

addAll

public boolean addAll(List l)

addAll

public boolean addAll(Collection c)

Description copied from class: AbstractObjectCollection

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Set

Overrides:

addAll in class AbstractObjectCollection

Parameters:

c - a collection.

Returns:

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

removeAll

public boolean removeAll(Collection c)

Description copied from class: AbstractObjectCollection

Remove from this collection all elements in the given collection. If the collection is an instance of this class, it uses faster iterators.

Specified by:

removeAll in interface Set

Overrides:

removeAll in class AbstractObjectCollection

Parameters:

c - a collection.

Returns:

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

retainAll

public boolean retainAll(Collection c)

Description copied from class: AbstractObjectCollection

Retains in this collection only elements from the given collection.

Specified by:

retainAll in interface Set

Overrides:

retainAll in class AbstractObjectCollection

Parameters:

c - a collection.

Returns:

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

toArray

public Object[] toArray()

Specified by:

toArray in interface Set

Overrides:

toArray in class AbstractObjectCollection

objectIterator

public ObjectIterator objectIterator()

Description copied from interface: ObjectCollection

Returns a type-specific iterator on the collection.

The iterator returned by the Collection.iterator() method and by this method are identical; however, using this method you can save a type casting.

Specified by:

objectIterator in interface ObjectCollection

See Also:

Collection.iterator()

size

public int size()

Specified by:

size in interface Set

clone

public Object clone()
