Method Detail

add

public boolean add(long k)

Specified by:

add in interface LongCollection

Overrides:

add in class AbstractLongCollection

contains

public boolean contains(long k)

Specified by:

contains in interface LongCollection

See Also:

Collection.contains(Object)

addAll

public boolean addAll(List l)

addAll

public boolean addAll(Collection c)

Description copied from class: AbstractLongCollection

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Set

Overrides:

addAll in class AbstractLongCollection

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: AbstractLongCollection

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 AbstractLongCollection

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: AbstractLongCollection

Retains in this collection only elements from the given collection.

Specified by:

retainAll in interface Set

Overrides:

retainAll in class AbstractLongCollection

Parameters:

c - a collection.

Returns:

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

addAll

public boolean addAll(LongList l)

addAll

public boolean addAll(LongCollection c)

Description copied from class: AbstractLongCollection

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

Specified by:

addAll in interface LongCollection

Overrides:

addAll in class AbstractLongCollection

Parameters:

c - a type-specific collection.

Returns:

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

removeAll

public boolean removeAll(LongCollection c)

Description copied from class: AbstractLongCollection

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

Specified by:

removeAll in interface LongCollection

Overrides:

removeAll in class AbstractLongCollection

Parameters:

c - a type-specific collection.

Returns:

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

retainAll

public boolean retainAll(LongCollection c)

Description copied from class: AbstractLongCollection

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

Specified by:

retainAll in interface LongCollection

Overrides:

retainAll in class AbstractLongCollection

Parameters:

c - a type-specific collection.

Returns:

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

toLongArray

public long[] toLongArray()

Description copied from interface: LongCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toLongArray in interface LongCollection

Overrides:

toLongArray in class AbstractLongCollection

longIterator

public LongIterator longIterator()

Description copied from interface: LongCollection

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:

longIterator in interface LongCollection

See Also:

Collection.iterator()

size

public int size()

Specified by:

size in interface Set

clone

public Object clone()
