Class TransformedList<S,T>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<T>

org.cyclos.utils.TransformedList<S,T>

Type Parameters:

S - The source element type

T - The target element type

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>

public class TransformedList<S,T>
extends AbstractList<T>

A read-only view of a list, transforming elements on get. Doesn't support indexOf(Object) and lastIndexOf(Object), because they would need to compare the transformed versions of the original list.
