Class NoNullValueHashMap

java.lang.Object

java.util.AbstractMap

java.util.HashMap

com.ibm.tivoli.maximo.dbmanage.NoNullValueHashMap

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public class NoNullValueHashMap
extends java.util.HashMap
implements java.util.Map

This HashMap will not store keys with null values. Unlike Hashtable, it will not throw an exception if put is called with a null value. Instead it will remove the key from the map.
