Method Details

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.

Specified by:

subList in interface IntList

Specified by:

subList in interface List<Integer>

Overrides:

subList in class IntLists.UnmodifiableList

See Also:

• List.subList(int,int)

add

public boolean add(int k)

Description copied from interface: IntCollection

Ensures that this collection contains the specified element (optional operation).

Specified by:

add in interface IntCollection

See Also:

• Collection.add(Object)

rem

public boolean rem(int k)

Description copied from interface: IntCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

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().

• Collection.contains(Object)

spliterator

public IntSpliterator spliterator()

Description copied from interface: IntCollection

Returns a type-specific spliterator on the elements of this collection.

See Collection.spliterator() for more documentation on the requirements of the returned spliterator.
