question: public void register ( NamedBean s ) { String systemName = s . getSystemName ( ) ; _tsys . put ( systemName , s ) ; String userName = s . getUserName ( ) ; if ( userName != null ) { _tuser . put ( userName , s ) ; } firePropertyChange ( "length" , null , Integer . valueOf ( _tsys . size ( ) ) ) ; s . addPropertyChangeListener ( this , "" , "Manager" ) ; }
target:  Remember a NamedBean Object created outside the manager. <P> The non-system-specific SignalHeadManagers use this method extensively.
