Class CompositeMap<K extends javax.xml.namespace.QName,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.xchain.framework.util.CompositeMap<K,V>

Type Parameters:

K - The type of key values. Must extend QName.

V - The key values.

All Implemented Interfaces:

java.util.Map<K,V>

public abstract class CompositeMap<K extends javax.xml.namespace.QName,V>
extends java.util.AbstractMap<K,V>

A map implementation that can use multiple maps. The maps are unmodified so if a map is attached and later modified, the modifications will be present in the CompositeMap.

Method Detail

mapList

protected abstract java.util.List<java.util.Map<K,V>> mapList()

Get a list of all the maps which make up this composite map. The order of the list is important as the first entry may be modified if the put() or clear() methods are used.

Returns:

A list of MapQName, V> objects.

firstMap

protected java.util.Map<K,V> firstMap()

Get the first map from mapList().

Returns:

A MapQName, V>.
