Class AbstractEntityManagerStore

java.lang.Object

public abstract class AbstractEntityManagerStore
extends Object
implements EntityManagerStore

Stores produced entity managers. When the EntityManagerProducer try to create an entity manager it will seach this store for a cached instance, only creating a new instance if this cache doesn't contain a suitable one.

There are several concrete implementations of this class, each one corresponding to a scoped cache (ex: RequestEntityManagerStore stores Entity Managers on the request scope). To select witch implementation is used (and with that, what scope is used to store Entity Managers) open the "demoiselle.properties" file and edit the property "frameworkdemoiselle.persistence.entitymanager.scope". The default scope is the RequestScoped.
