In fact I have in my component's API, I have methods like the following:
<idl>
interface XMElement: com::sun::star::uno::XInterface {
void setProperty([in] string sName, [in] string sValue);
};
</idl>
However, the sName parameter is actually a GStreamer string... which
isn't good for a generic API. I'd like to have some UNO constants to use
instead. The problem is how to make the mapping between the UNO
Constants (or their string representation) and the GStreamer strings.
For example, I'ld to use:
<c++>
//FILE_LOCATION is a UNO Constant defined in my API to be mapped on the
//Gstreamer "location" string...
myElement.setProperty(FILE_LOCATION, "/path/to/my/file);
</c++>
instead of:
<c++>
// "location" is a GStreamer dependent string :(
myElement.setProperty("location", "/path/to/my/file");
</c++>
I hope that was clearer this time.
