| TransformedCollection | | public class TransformedCollection extends AbstractSerializableCollectionDecorator (Code) | | Decorates another Collection to transform objects that are added.
The add 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.
