Package org.springframework.data.cassandra.util

Class MapBuilder<K,V>

java.lang.Object

org.springframework.data.cassandra.util.MapBuilder<K,V>

Type Parameters:

K - The key type of the map.

V - The value type of the map.

All Implemented Interfaces:

Map<K,V>

public class MapBuilder<K,V>
extends Object
implements Map<K,V>

Builder for maps, which also conveniently implements Map via delegation for convenience so you don't have to actually build() it.
