Class SafeVector<ELEMENTTYPE>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<E>

java.util.Vector<ELEMENTTYPE>

com.helger.commons.collections.list.SafeVector<ELEMENTTYPE>

Type Parameters:

ELEMENTTYPE - The type of the elements in the list

All Implemented Interfaces:

IHasSize, Serializable, Cloneable, Iterable<ELEMENTTYPE>, Collection<ELEMENTTYPE>, List<ELEMENTTYPE>, RandomAccess

@ThreadSafe
public class SafeVector<ELEMENTTYPE>
extends Vector<ELEMENTTYPE>
implements IHasSize

This is a specialized Vector that can handle read accesses on list items that are not yet in the container. If get(int) is called with an index that would normally throw an ArrayIndexOutOfBoundsException this class will fill all indices between the current Vector.size() and the desired index with values provided by an IFactory. If you don't pass an IFactory in the constructor a default factory returning null values is used.
