    • Method Detail

      • _p_getType

        public Class<?> _p_getType()
        Description copied from interface: PersistentIF
        INTERNAL: Returns the object.type. This information is used by the transaction to handle the persistent mapping for the object.
        Specified by:
        _p_getType in interface PersistentIF

      • syncFieldsAfterMerge

        protected void syncFieldsAfterMerge​(IdentityIF source,

                                    int... fields)

      • loadField

        protected <F> F loadField​(int field)
        INTERNAL: Called when the instance requests the initialization of the specified field value. This call will lead to the value being retrieved from the data repository if the instance is managed by a transaction, otherwise a default value will be set.
        Returns:
        FIXME: only loaded values will be returned. if the default value is being set, the return value is null.
