Class ReadOnlyListIterator<E>
java.lang.Object
one.microstream.util.iterables.ReadOnlyListIterator<E>
- All Implemented Interfaces:
Iterator<E>
,ListIterator<E>
public class ReadOnlyListIterator<E> extends Object implements ListIterator<E>
Generic (and potentially imperformant!) implementation of a
Routes all modifying procedures (
ListIterator
.Routes all modifying procedures (
add(Object)
, remove()
, set(Object)
) to the wrapped
List
which may throw an UnsupportedOperationException
if it does not support the procedure.
If the use of an Iterator is not mandatory (e.g. through an API), it is strongly recommended to instead use
higher order programming concepts from "Collection 2.0" types like XGettingList
, XList
, etc.
and their functional procedures etc.
Note that while implementing ListIterator
, this iterator can handle any sequence as it is read only,
meaning it can be used for iterating e.g. XGettingEnum
collections as well.
