      • loading

        public void loading​(java.lang.Object objClass,
                    java.lang.Object identity)
        Description copied from interface: LogInterceptor
        Called to indicate that an object of the given type and identity is about to be loaded into memory.

        This method is called when the cache engine decides to explicitly load the specified object from persistent storage and not use a cached copy. It is called prior to the retrieval.

        Specified by:
        loading in interface LogInterceptor
        Parameters:
        objClass - The type of the object
        identity - The object identity

      • creating

        public void creating​(java.lang.Object objClass,
                     java.lang.Object identity)
        Description copied from interface: LogInterceptor
        Called to indicate that an object of the given type and identity is about to be created in persistent storage.

        This method is called when the cache engine decides to explicitly create the specified object in persistent storage, either in response to a create method or upon transaction commit. It is called prior to the creation.

        Specified by:
        creating in interface LogInterceptor
        Parameters:
        objClass - The type of the object
        identity - The object identity

      • removing

        public void removing​(java.lang.Object objClass,
                     java.lang.Object identity)
        Description copied from interface: LogInterceptor
        Called to indicate that an object of the given type and identity is about to be deleted from persistent storage.

        This method is called when the cache engine decides to explicitly delete the specified object from persistent storage, either in response to a delete method or upon transaction commit. It is called prior to the deletion.

        Specified by:
        removing in interface LogInterceptor
        Parameters:
        objClass - The type of the object
        identity - The object identity

      • storing

        public void storing​(java.lang.Object objClass,
                    java.lang.Object identity)
        Description copied from interface: LogInterceptor
        Called to indicate that an object of the given type and identity is about to be stored in persistent storage.

        This method is called when the cache engine decides to explicitly store the specified object in persistent storage, after detecting a modification in this object. It is called prior to storage.

        Specified by:
        storing in interface LogInterceptor
        Parameters:
        objClass - The type of the object
        identity - The object identity
