      • addSingleInstanceListener

        void addSingleInstanceListener​(SingleInstanceListener sil)
        Adds the specified SingleInstanceListener to handle how the application/applet should behave when another instance of the same application/applet is invoked. If SingleInstanceListener sil is null, no exception is thrown and no action is performed.
        Parameters:
        sil - the SingleInstanceListener object to be added

      • removeSingleInstanceListener

        void removeSingleInstanceListener​(SingleInstanceListener sil)
        Removes the specified SingleInstanceListener. This method performs no function, nor does it throw an exception, if the listener specified by the argument was not previously added to the application/applet. If listener sil is null, no exception is thrown and no action is performed. It is recommended that if an application/applet registered any SingleInstanceListener(s), it should call this method to remove all listeners upon exit of the application/applet.
        Parameters:
        sil - the SingleInstanceListener object to be removed
