Examples of EntityManager

com.cloud.utils.db.EntityManager
Generic Entity Manager to retrieve database objects.
com.echoeight.bison.entity.EntityManager
com.l2client.controller.entity.EntityManager
Singleton which manages entities, components and queries around them. @see ComponentSystem
com.pointcliki.core.EntityManager
The EntityManager is a global tracker of Entities that allows classes to always maintain a way of accessing the correct versions of entities in the game. Because entities are cloned when they are saved, it may be difficult to ensure that references to entities are kept up to date, so they should instead use an EntityQuery which automatically retrieves the latest entity if an older or different game state is loaded. An entity has an ID which is unique to that entity for the duration it is attached to a scene. When an entity changes scene, it is re-registered so that the entity can be restored in its previous scene if that scene loads an older game state where the entity was still parented to that scene. @see EntityQuery @author hugheth @since 1

javax.persistence.EntityManager
Interface used to interact with the persistence context. An EntityManager instance is associated with a persistence context. A persistence context is a set of entity instances in which for any persistent entity identity there is a unique entity instance. Within the persistence context, the entity instances and their lifecycle are managed. This interface defines the methods that are used to interact with the persistence context. The EntityManager API is used to create and remove persistent entity instances, to find entities by their primary key, and to query over entities. The set of entities that can be managed by a given EntityManager instance is defined by a persistence unit. A persistence unit defines the set of all classes that are related or grouped by the application, and which must be colocated in their mapping to a single database. @author Emmanuel Bernard
