public interface ReferenceList<K>
A type-specific List
; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this interface strengthens iterator()
, listIterator()
,
listIterator(int)
and subList(int,int)
. The former had been already
strengthened upstream, but unfortunately List
re-specifies it.
Besides polymorphic methods, this interfaces specifies methods to copy into an array or remove contiguous sublists. Although the abstract implementation of this interface provides simple, one-by-one implementations of these methods, it is expected that concrete implementation override them with optimized versions.
