      • initialize

        public static void initialize​(java.lang.Object proxy)
                       throws HibernateException
        Force initialization of a proxy or persistent collection.

        Note: This only ensures intialization of a proxy object or collection; it is not guaranteed that the elements INSIDE the collection will be initialized/materialized.

        Parameters:
        proxy - a persistable object, proxy, persistent collection or null
        Throws:
        HibernateException - if we can't initialize the proxy at this time, eg. the Session was closed

      • isInitialized

        public static boolean isInitialized​(java.lang.Object proxy)
        Check if the proxy or persistent collection is initialized.
        Parameters:
        proxy - a persistable object, proxy, persistent collection or null
        Returns:
        true if the argument is already initialized, or is not a proxy or collection

      • getClass

        public static java.lang.Class getClass​(java.lang.Object proxy)
        Get the true, underlying class of a proxied persistent class. This operation will initialize a proxy by side-effect.
        Parameters:
        proxy - a persistable object or proxy
        Returns:
        the true class of the instance
        Throws:
        HibernateException

      • getLobCreator

        public static LobCreator getLobCreator​(Session session)
        Obtain a lob creator for the given session.
        Parameters:
        session - The session for which to obtain a lob creator
        Returns:
        The log creator reference

      • getLobCreator

        public static LobCreator getLobCreator​(SharedSessionContractImplementor session)
        Obtain a lob creator for the given session.
        Parameters:
        session - The session for which to obtain a lob creator
        Returns:
        The log creator reference

      • getLobCreator

        public static LobCreator getLobCreator​(SessionImplementor session)
        Obtain a lob creator for the given session.
        Parameters:
        session - The session for which to obtain a lob creator
        Returns:
        The log creator reference

      • close

        public static void close​(java.util.Iterator iterator)
                  throws HibernateException
        Close an Iterator instances obtained from Query.iterate() immediately instead of waiting until the session is closed or disconnected.
        Parameters:
        iterator - an Iterator created by iterate()
        Throws:
        HibernateException - Indicates a problem closing the Hibernate iterator.
        java.lang.IllegalArgumentException - If the Iterator is not a "Hibernate Iterator".
        See Also:
        Query.iterate()

      • isPropertyInitialized

        public static boolean isPropertyInitialized​(java.lang.Object proxy,
                                            java.lang.String propertyName)
        Check if the property is initialized. If the named property does not exist or is not persistent, this method always returns true.
        Parameters:
        proxy - The potential proxy
        propertyName - the name of a persistent attribute of the object
        Returns:
        true if the named property of the object is not listed as uninitialized; false otherwise

      • unproxy

        public static java.lang.Object unproxy​(java.lang.Object proxy)
        Unproxies a HibernateProxy. If the proxy is uninitialized, it automatically triggers an initialization. In case the supplied object is null or not a proxy, the object will be returned as-is.
        Parameters:
        proxy - the HibernateProxy to be unproxied
        Returns:
        the proxy's underlying implementation object, or the supplied object otherwise
