Class CollectionMap<K,V>

java.lang.Object

com.serenegiant.utils.CollectionMap<K,V>

Type Parameters:

K -

V -

All Implemented Interfaces:

java.util.Map<K,java.util.Collection<V>>

public class CollectionMap<K,V>
extends java.lang.Object
implements java.util.Map<K,java.util.Collection<V>>

Map holds multiple values for each key This class use HashMap as Map and ArrayList as Collection as default. You can override this by overriding #createContentsMap and #createCollection.
