public class Arg
extends Object

Helper class to build arguments in a service request. Arguments are the "leaf" objects at the end of a property path and can be of several types depending on what you want to do with them. This class adds an additional help level to using Request and Profile. Following the example in Profile, thanks to Arg it could be:

Example: Calling a Lighting service that controls LightSources of type ElectricLight, find the light with URI "desiredURI" and turn it off (set to brightness 0)

Request req=new Request(new Lighting(null));

req.put(Path.at(Lighting.PROP_CONTROLS).to(LightSource.PROP_HAS_TYPE), Arg.type(ElectricLight.MY_URI));

req.put(Path.at(Lighting.PROP_CONTROLS), Arg.in(new LightSource(desiredURI)));

req.put(Path.at(Lighting.PROP_CONTROLS).to(LightSource.PROP_SOURCE_BRIGHTNESS), Arg.change(new Integer(0)));

caller.call(req);
