Package Summary  Overview Summary

class:ServiceUIFactory [NONE]



  • public abstract class ServiceUIFactory
    extends Object
    
    Services may optionally provide UIs which allow different styles of interaction in different roles. One role may be end-user browsing and setting of print options. Another role may be administering the print service.

    Although the Print Service API does not presently provide standardised support for administering a print service, monitoring of the print service is possible and a UI may provide for private update mechanisms.

    The basic design intent is to allow applications to lazily locate and initialize services only when needed without any API dependencies except in an environment in which they are used.

    Swing UIs are preferred as they provide a more consistent L&F and can support accessibility APIs.

    Example usage:

      ServiceUIFactory factory = printService.getServiceUIFactory();
      if (factory != null) {
          JComponent swingui = (JComponent)factory.getUI(
                                             ServiceUIFactory.MAIN_UIROLE,
                                             ServiceUIFactory.JCOMPONENT_UI);
          if (swingui != null) {
              tabbedpane.add("Custom UI", swingui);
          }
      }

  • getUI

    public abstract Object getUI​(int role,
                                 String ui)
    Get a UI object which may be cast to the requested UI type by the application and used in its user interface.

method:getUIClassNamesForRole(int) [NONE]

  • getUIClassNamesForRole

    public abstract String[] getUIClassNamesForRole​(int role)
    Given a UI role obtained from this factory obtain the UI types available from this factory which implement this role. The returned Strings should refer to the static variables defined in this class so that applications can use equality of reference ("==").
    Parameters:
    role - to be looked up.
    Returns:
    the UI types supported by this class for the specified role, null if no UIs are available for the role.
