Method Detail

locate

public EntityInformation[] locate(SessionFactory sessionFactory,
                                  HibernateGpsDevice device)
                           throws HibernateGpsDeviceException

Description copied from interface: HibernateEntitiesLocator

Locates the entities used for the index operation.

Specified by:

locate in interface HibernateEntitiesLocator

Parameters:

sessionFactory - The SessionFactory to be optionally used for locating the entities.

device - The Hibernate device that called this locator.

Returns:

An array of the enteties that need to be indexed during the index operation.

Throws:

HibernateGpsDeviceException

shouldFilter

protected boolean shouldFilter(String entityname,
                               ClassMetadata classMetadata,
                               Map allClassMetaData,
                               HibernateGpsDevice device)

Returns true if the entity name needs to be filtered.

Implementation filteres out inherited hibernate mappings, since the select query for the base class will cover any inherited classes as well.

Note, that this method is called after it has been verified that the class has Compass mappings (either directly, or indirectly by an interface or a super class).

Parameters:

entityname - The name of the entity

classMetadata - The Hibernate class meta data.

device - The Hibernate Gps device

Returns:

true if the entity should be filtered out, false if not.
