public interface DoubleList extends List<Double>, Comparable<List<? extends Double>>, DoubleCollection
A type-specificList
; provides some additional methods that use polymorphism to avoid (un)boxing.Note that this type-specific interface extends
Comparable
: it is expected that implementing classes perform a lexicographical comparison using the standard operator "less then" for primitive types, and the usualcompareTo()
method for objects.Additionally, this interface strengthens
listIterator()
,listIterator(int)
andsubList(int,int)
.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.
