Class JSONMapEntityStoreMixin

java.lang.Object
  org.qi4j.spi.entitystore.helpers.JSONMapEntityStoreMixin

All Implemented Interfaces:

EntityStore, EntityStoreSPI, JSONMapEntityStoreActivation, StateStore

public class JSONMapEntityStoreMixin
extends java.lang.Object
implements EntityStore, EntityStoreSPI, StateStore, JSONMapEntityStoreActivation

Implementation of EntityStore that works with an implementation of MapEntityStore.

Implement MapEntityStore and add as mixin to the service using this mixin.

See MemoryMapEntityStoreMixin for reference.

EntityStores based on this mixin gets support for the Migration and Cache extensions.

MapEntityStore implementations will get their values as JSON.
