public abstract class TransformingList<OE,IE>
extends AbstractList<OE>

Represents a list that dynamically transforms the elements of another list. This abstract class defines a list containing an inner list of elements of a certain type, and provides facilities to convert these inner elements to outer elements of another type. A concrete subclass simply needs to provide methods for converting between the inner and the outer types.@param <IE> the inner type of the elements.

Constructor Summary

TransformingList(List<IE> fromList)
