Class JPASearchFacade

java.lang.Object

com.googlecode.genericdao.search.jpa.JPASearchFacade

All Implemented Interfaces:

SearchFacade

public class JPASearchFacade
extends Object
implements SearchFacade

JPA implementation of SearchFacade.

The SearchProcessor and EntityManager must be set in order for the SearchFacade to function. Generally, a single SearchProcessor will be associated with an instance of JPASearchFacade for the lifetime of the instance, while a new "current" EntityManager will be injected as needed. Make sure that any EntityManager that is used is associated with the same persistence unit (i.e. EntityManagerFactory) as the SearchProcessor.
