Class JPASearchProcessor

java.lang.Object
  com.trg.search.BaseSearchProcessor
      com.trg.search.jpa.JPASearchProcessor

public class JPASearchProcessor
extends BaseSearchProcessor

Implementation of BaseSearchProcessor that works with JPA.

This class is designed to be used as a singleton. The constructor requires a MetadataUtil instance. Each MetadataUtil instance is typically associated with a single persistence unit (i.e. EntityManagerFactory). A JPASearchProcessor can only be used with EntityManagers that are associated with the same persistence unit as the MetadataUtil. If an application has multiple persistence units, it will need to have multiple corresponding Search Processors.
