http://api.openoffice.org/docs/common/ref/com/sun/star/script/provider/Scri
ptURIHelper.html for the service description ("This service is used to help
transform Scripting Framework storage locations to Scripting Framework
script URIs and vice versa."), this *seems* to be what you're looking for
(didn't try it yet in Basic, as there is no simple way to instantiate a
new-style service here;
I must admit that I don't know the exact meaning of "new-style service" but
a new style service is one that in order to get an instance, you don't
have *first* to instantiate it at the service manager by its name and
*then* get a reference to its interface(s) (because createInstance...
returns a generic XInterface that has to be safely casted).
In Java:
Object oDesktop = xContext.getServiceManager().createInstanceWithContext(
"com.sun.star.frame.Desktop", xContext);
XDesktop xDesktop = (XDesktop) UnoRuntime.queryInterface(
XDesktop.class, oDesktop);
XComponentLoader xComponentLoader = (XComponentLoader)
UnoRuntime.queryInterface(
XComponentLoader.class, xDesktop);
A new style service has constructor(s) to instantiate it, and directly
returns a reference to its interface.
For example
http://api.openoffice.org/docs/common/ref/com/sun/star/deployment/ui/PackageManagerDialog.html
XAsynchronousExecutableDialog xPackageManagerDialog =
PackageManagerDialog.create(xContext, xWindow,
sContext);
For strictly type-safe languages like Java and C++ new-style services
(together with multiple inheritance) make things *simpler*, as seen in
the examples above.
But for OOo *Basic*, where we already have the simple
createUnoService(), things are - IMO - made *harder* ...
I've tried with createInstanceWithArguments on the service manager and it
seems to work:
... as one can't use with them the createUnoService() shortcut, but
createInstanceWithArgumentsAndContext
Notice that one has to use the
css.lang.XMultiComponentFactory:createInstanceWithContext/createInstanceWithArgumentsAndContext,
not the old
css.lang.XMultiServiceFactory:createInstance/createInstanceWithArguments,
although the former still works; see Jürgen's comment on
http://api.openoffice.org/servlets/ReadMsg?list=dev&msgNo=18526
And even this is not completely "safe" in OOo Basic, as it is
implementation specific; quoting Frank's in
http://api.openoffice.org/servlets/ReadMsg?list=dev&msgNo=18530
"So, the bottom line is: createInstanceWithArguments[AndContext] *might*
work, but if it doesn't (or stops working the next version), don't
complain."
Frank's issue requesting support for new-style service constructors in
Basic is http://www.openoffice.org/issues/show_bug.cgi?id=82918,
targeted to 3.X due to lack of resources.
Regards
Ariel.
