Class CheckedListPlus<T>

java.lang.Object

eu.bandm.tools.umod.runtime.CheckedList<T>

eu.bandm.tools.tdom.runtime.CheckedListPlus<T>

All Implemented Interfaces:

Serializable, Iterable<T>, Collection<T>, List<T>, SequencedCollection<T>

public class CheckedListPlus<T>
extends CheckedList<T>

Extends the checked list to ensure that it does not become empty. Esp. there is no constructor for an empty instance.
Please note: this class (and its superclass) are safe only against accidental errors, not against malicious attacks e.g. by subclassing.
