Class BasicMapId

java.lang.Object

org.springframework.data.cassandra.core.mapping.BasicMapId

All Implemented Interfaces:

Map<String,Object>, MapId

public class BasicMapId
extends Object
implements MapId

Simple implementation of MapId.

Note: This could be extended in various cool ways, like one that takes a type and validates that the given name corresponds to an actual field or bean property on that type. There could also be another one that uses a CassandraPersistentEntity and CassandraPersistentProperty instead of a String name.
