Method Detail

getCompass

public static Compass getCompass(javax.persistence.EntityManagerFactory emf)

Returns the Compass instance assoicated with the given Hibernate EntityManagerFactory. This allows to get a Compass instnace in order to perform search operations for example outside of a JPA transaction (for performance reasons, mostly there is no need to start a DB transaction).

getCompassTemplate

public static CompassTemplate getCompassTemplate(javax.persistence.EntityManagerFactory emf)

Returns the CompassTemplate instance assoicated with the given Hibernate EntityManagerFactory. This allows to get a Compass instnace in order to perform search operations for example outside of a JPA transaction (for performance reasons, mostly there is no need to start a DB transaction).

getCompass

public static Compass getCompass(javax.persistence.EntityManager em)

Returns the Compass instance assoicated with the given OpenJPA EntityManager. This allows to get a Compass instnace in order to perform search operations for example outside of a JPA transaction (for performance reasons, mostly there is no need to start a DB transaction).

getCompassTemplate

public static CompassTemplate getCompassTemplate(javax.persistence.EntityManager em)

Returns the CompassTemplate instance assoicated with the given OpenJPA EntityManager. This allows to get a Compass instnace in order to perform search operations for example outside of a JPA transaction (for performance reasons, mostly there is no need to start a DB transaction).

getIndexSettings

public static Properties getIndexSettings(javax.persistence.EntityManagerFactory emf)

Returns the index settings that are configured within the EntityManagerFactory configuration. Can be used to configure exteranally a JpaCompassGps instance.

getIndexSettings

public static Properties getIndexSettings(javax.persistence.EntityManager em)

Returns the index settings that are configured within the EntityManager configuration. Can be used to configure exteranally a JpaCompassGps instnace.

getCompassGps

public static JpaCompassGps getCompassGps(javax.persistence.EntityManagerFactory emf)

Returns a new instnacoef of a JpaCompassGps built on top of the embedded Compass instance.

getCompassGps

public static JpaCompassGps getCompassGps(JpaGpsDevice device)

Returns a new instnacoef of a JpaCompassGps built on top of the embedded Compass instance.
