Detailed Description

Data holder for a UPnP service, parsed from the device XML description.

The discovery code does not download the service description documents, and the only set values after discovery are those available from the device description (serviceId, SCPDURL, controlURL, eventSubURL). You can call fetchAndParseDesc() to obtain a parsed version of the service description document, with all the actions and state variables. This is mostly useful if you need to retrieve some min/max values for the state variable, in case there is no action defined to retrieve them (e.g. min/max volume values for AVT RenderingControl). Also, if you wanted to define dynamic methods from the description data.
