contains in interface LongCollection
Overrides:
contains in class AbstractLongList
See Also:
Collection.contains(Object)

addAll

public boolean addAll(Collection<? extends Long> c)
Description copied from class: AbstractLongList
Delegates to a more generic method.

Specified by:
addAll in interface Collection<Long>
Specified by:
addAll in interface List<Long>
Overrides:
addAll in class AbstractLongList
Parameters:
c - a collection.

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

addAll

public boolean addAll(int i,
                      Collection<? extends Long> c)
Specified by:
addAll in interface List<Long>
Overrides:
addAll in class AbstractLongList

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 List<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 List<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()

listIterator

public LongListIterator listIterator()
Description copied from interface: LongList
Returns a type-specific list iterator on the list.

Specified by:
listIterator in interface LongList
Specified by:
listIterator in interface List<Long>
Overrides:
listIterator in class AbstractLongList
See Also:
List.listIterator()

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 LongList
Specified by:
iterator in interface Iterable<Long>
Specified by:
iterator in interface Collection<Long>
Specified by:
iterator in interface List<Long>
Overrides:
iterator in class AbstractLongList
Returns:
a type-specific iterator on the elements of this collection.

listIterator

public LongListIterator listIterator(int i)
Description copied from interface: LongList
Returns a type-specific list iterator on the list starting at a given index.

Specified by:
listIterator in interface LongList
Specified by:
listIterator in interface List<Long>
Overrides:
listIterator in class AbstractLongList
See Also:
List.listIterator(int)

subList

public LongList subList(int from,
                        int to)
Description copied from interface: LongList
Returns a type-specific view of the portion of this list from the index from, inclusive, to the index to, exclusive.

Note that this specification strengthens the one given in List.subList(int,int).

Specified by:
subList in interface LongList
Specified by:
subList in interface List<Long>
Overrides:
subList in class AbstractLongList
See Also:
List.subList(int,int)

size

public int size()
Specified by:
size in interface Collection<Long>
Specified by:
size in interface List<Long>
Specified by:
size in class AbstractCollection<Long>

size

public void size(int size)
Description copied from interface: LongList
Sets the size of this list.

If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

Specified by:
size in interface LongList
Overrides:
size in class AbstractLongList
Parameters:
size - the new size.

clear

public void clear()
Specified by:
clear in interface Collection<Long>
Specified by:
clear in interface List<Long>
Overrides:
clear in class AbstractCollection<Long>

clone

public Object clone()
Overrides:
clone in class Object

rem

public boolean rem(long k)
Description copied from interface: LongCollection
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().

Specified by:
rem in interface LongCollection
Overrides:
rem in class AbstractLongList
See Also:
Collection.remove(Object)

addAll

public boolean addAll(LongCollection c)
Description copied from class: AbstractLongCollection

Overrides:
addAll in class AbstractLongList
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.
See Also:
Collection.addAll(Collection)

addAll

public boolean addAll(int i,
                      LongCollection c)
Description copied from class: AbstractLongList
Delegates to a more generic method.

addAll in interface LongList
Overrides:
addAll in class AbstractLongList
