Return errors from property set / get

[Maddimax]

I would like to return errors from my get / set property functions. I'm using the IDL generated Adaptor classes, but I can't see any way to return an error state from those.

Am I missing something?

It would be great if I could for instance throw an sdbus::Error in the getter / setter, and have sdbus translate that into an error response.

Nevermind, I found that "SDBUS_THROW_ERROR" does the trick. Maybe documenting that makes sense?

The tutorial shows in several places (e.g. in a code snippet under https://github.com/Kistler-Group/sdbus-cpp/blob/master/docs/using-sdbus-c%2B%2B.md#providing-server-implementation-based-on-generated-adaptors) that server-side methods can simply throw sdbus::Error to signal/return errors to the caller.
