iterator

public FloatListIterator iterator()

Description copied from class: AbstractFloatList

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.

This implementation delegates to AbstractFloatList.listIterator().

Specified by:

Returns:

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

See Also:

Iterable.iterator()

listIterator

Description copied from class: AbstractFloatList

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

This implementation is based on the random-access methods.

Specified by:

listIterator in interface FloatList

Specified by:

listIterator in interface List<Float>

Overrides:

listIterator in class AbstractFloatList

See Also:

List.listIterator(int)

subList
