Overrides:

contains in class AbstractIntList

See Also:

Collection.contains(Object)

addAll

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

Description copied from class: AbstractIntList

Delegates to a more generic method.

Specified by:

addAll in interface Collection<Integer>

Specified by:

addAll in interface List<Integer>

Overrides:

addAll in class AbstractIntList

Parameters:

c - a collection.

Returns:

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

addAll

public boolean addAll(int i,
                      Collection<? extends Integer> c)

Specified by:

addAll in interface List<Integer>

Overrides:

addAll in class AbstractIntList

removeAll

public boolean removeAll(Collection<?> c)

Description copied from class: AbstractIntCollection

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<Integer>

Specified by:

removeAll in interface List<Integer>

Overrides:

removeAll in class AbstractIntCollection

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: AbstractIntCollection

Retains in this collection only elements from the given collection.

Specified by:

retainAll in interface Collection<Integer>

Specified by:

retainAll in interface List<Integer>

Overrides:

retainAll in class AbstractIntCollection

Parameters:

c - a collection.

Returns:

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

toIntArray

public int[] toIntArray()

Description copied from interface: IntCollection

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

Specified by:

toIntArray in interface IntCollection

Overrides:

toIntArray in class AbstractIntCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

listIterator

public IntListIterator listIterator()

Description copied from interface: IntList

Returns a type-specific list iterator on the list.

Specified by:

listIterator in interface IntList

Specified by:

listIterator in interface List<Integer>

Overrides:

listIterator in class AbstractIntList

See Also:

List.listIterator()

iterator

public IntListIterator iterator()

Description copied from interface: IntCollection

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 IntCollection

Specified by:

iterator in interface IntIterable

Specified by:

iterator in interface IntList

Specified by:

iterator in interface Iterable<Integer>

Specified by:

iterator in interface Collection<Integer>

Specified by:

iterator in interface List<Integer>

Overrides:

iterator in class AbstractIntList

Returns:

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

listIterator

public IntListIterator listIterator(int i)

Description copied from interface: IntList

Returns a type-specific list iterator on the list starting at a given index.

Specified by:

listIterator in interface IntList

Specified by:

listIterator in interface List<Integer>

Overrides:

listIterator in class AbstractIntList

See Also:

List.listIterator(int)

subList

public IntList subList(int from,
                       int to)

Description copied from interface: IntList

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 IntList

Specified by:

subList in interface List<Integer>

Overrides:

subList in class AbstractIntList

See Also:

List.subList(int,int)

size

public int size()

Specified by:

size in interface Collection<Integer>

Specified by:

size in interface List<Integer>

Specified by:

size in class AbstractCollection<Integer>

size

public void size(int size)

Description copied from interface: IntList

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 IntList

Overrides:

size in class AbstractIntList

Parameters:

size - the new size.

clear

public void clear()

Specified by:

clear in interface Collection<Integer>

Specified by:

clear in interface List<Integer>

Overrides:

clear in class AbstractCollection<Integer>

clone

public Object clone()

Overrides:

clone in class Object

rem

public boolean rem(int k)

Description copied from interface: IntCollection

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 IntCollection

Overrides:

rem in class AbstractIntList

See Also:

Collection.remove(Object)

addAll

public boolean addAll(IntCollection c)

Description copied from class: AbstractIntCollection
