java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

org.wandora.utils.EasyHash<K,V>

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map<K,V>

public class EasyHash<K,V>
extends java.util.HashMap<K,V>

EasyHash is an extended HashMap with one added constructor and one initialization method. The new constructor makes it possible to more easily create a new HashMap instance. For example, this associates letters with numbers: EasyHash eh=new EasyHash(new Object[] { "a",new Integer(1), "b",new Integer(2), "c",new Integer(3), "d",new Integer(4) });

Constructor Detail

EasyHash

public EasyHash(java.lang.Object... a)

Creates new EasyHash from an array of objects.

Parameters:

a - The objects to be fed to setArray. a[n] will be associated with a[n+1]. The number of elements in a should therefore be even. If it isn't, the last element will be ignored.

Method Detail

setArray

public void setArray(java.lang.Object... a)

Adds the given objects to this EasyHash.

Parameters:

a - The objects to be added. a[n] will be associated with a[n+1]. The number of elements in a should therefore be even. If it isn't, the last element will be ignored.
