service ProtocolHandler
Description special dispatch provider registered for URL protocols The generic dispatch mechanism on a Frame search for such registered protocol handler and use it if it agrees with the dispatched URL. Supported URLs must match follow format: : If a handler provides optional arguments ("?") or jump marks ("#") depends from his defintion and implementation. The generic dispatch provider will use registered URL pattern to detect right handler.

Exported Interfaces
XDispatchProvider | Description used from the generic dispatch mechanism of the frame, to ask ProtocolHandler for his agreement for the dispatched URL Such asked handler can agree by returning itself or a special sub dispatch object, which can handle the given URL. Of course he can disagree with it by returning an empty reference.
::com::sun::star::lang::XInitialization | [ OPTIONAL ] Description initialize the new handler instance with some context informations Sometimes it can be usefull for a handler object, to know something about the environment, in which it runs - especily the frame. For this case the generic code (which uses the handler) will ask for this optional interface and use it, if it exist. Following parameters are passed to the service: sequence< any > [0] => the frame for which this ProtocolHandler was created [com.sun.star.frame.XFrame] Please note: if this mechanism is used it seams not usefull (nor possible) to implement a ProtocolHandler as a singleton. Otherwhise the implementation can't distinguish between different environments and her corresponding dispatch requests.
