Method Detail

add

public boolean add(long k)

Specified by:

add in interface LongCollection

Overrides:

add in class AbstractLongCollection

See Also:

Collection.add(Object)

contains

public boolean contains(long k)

Specified by:

contains in interface LongCollection

Overrides:

contains in class AbstractLongCollection

addAll

public boolean addAll(Collection<? extends Long> c)

Description copied from class: AbstractLongCollection

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Collection<Long>

Specified by:

addAll in interface Set<Long>

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 Collection<Long>

Specified by:

removeAll in interface Set<Long>

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 Collection<Long>

Specified by:

retainAll in interface Set<Long>

Overrides:

retainAll in class AbstractLongCollection

Parameters:

c - a 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

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

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.

See Also:

Collection.addAll(Collection)

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.

See Also:

Collection.removeAll(Collection)

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.

See Also:

Collection.retainAll(Collection)

iterator

public LongListIterator iterator()

Description copied from interface: LongCollection

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 LongCollection

Specified by:

iterator in interface LongIterable

Specified by:

iterator in interface LongSet

Specified by:

iterator in interface Iterable<Long>

Specified by:

iterator in interface Collection<Long>

Specified by:

iterator in interface Set<Long>

Specified by:

iterator in class AbstractLongSet

Returns:

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

size

public int size()

Specified by:

size in interface Collection<Long>

Specified by:

size in interface Set<Long>

Specified by:

size in class AbstractCollection<Long>

clone

public Object clone()

Overrides:

clone in class Object
