        java.util.Map<java.lang.Class<?>,​java.util.Map<java.lang.String,​CachedEntity>> getAllCachedEntities()
        Returns all cached Entity instances as a map with following structure: { entityClassName, {entityId, entity} }

      • put

                 boolean storeState)
        Adds the gives Entity to the cache.

        Returns:
        Returns a CachedEntity instance, which can be enriched later on.

      • findInCache

        <T> T findInCache​(java.lang.Class<T> entityClass,
                  java.lang.String id)
        Returns the cached Entity instance of the given class with the provided id. Returns null if such a Entity cannot be found.

      • findInCache

        <T> java.util.List<T> findInCache​(java.lang.Class<T> entityClass)
        Returns all cached Entity instances of a given type. Returns an empty list if no instances of the given type exist.

      • findInCacheAsCachedObjects

        <T> java.util.Collection<CachedEntity> findInCacheAsCachedObjects​(java.lang.Class<T> entityClass)
        Returns all CachedEntity instances for the given type. The difference with findInCache(Class) is that here the whole CachedEntity is returned, which gives access to the persistent state at the moment of putting it in the cache.

      • cacheRemove

        void cacheRemove​(java.lang.Class<?> entityClass,
                 java.lang.String entityId)
        Removes the Entity of the given type with the given id from the cache.
