      java.util.AbstractList<E>
          java.util.Vector<Object>
              org.makumba.commons.MultipleKey

All Implemented Interfaces:

Serializable, Cloneable, Iterable<Object>, Collection<Object>, List<Object>, RandomAccess

public class MultipleKey
extends Vector<Object>
implements Serializable

Holds the values for a group of fields. Every element of a MultipleKey holds an Object. In case of a null value being passed to one of the constructors, the element is replaced by a placeholder.
