Interface TransformedList<I,O>

Type Parameters:

I - the backing list's element type

O - this list's element type

All Superinterfaces:

Collection<O>, ExtendedList<O>, ExtendedReorderableList<O>, Iterable<O>, List<O>, RandomAccess

All Known Implementing Classes:

DefaultTransformedList

public interface TransformedList<I,O>
extends ExtendedReorderableList<O>

A view for a list where every element appears transformed. That is, if source is the backing list and function the element transformation function,

this.get(i) returns the same value as function.apply(source.get(i)) for any i < source.size().

Element order is taken from the source list. By consequence, changing this list's element order changes the source list's element order.

This view is read-only, i.e. its modifying operations throw an UnsupportedOperationException.
