Class TransformedList
- Collection, List, Serializable
public class TransformedList
implements List
Decorates another
List
to transform objects that are added.
The add and set methods are affected by this class.
Thus objects must be removed or searched for using their transformed form.
For example, if the transformation converts Strings to Integers, you must
use the Integer form to remove objects.
This class is Serializable from Commons Collections 3.1.
