Making RTCSessionDescription and RTCIceCandidate much more flexible

Hello list members,

Today I would like to propose a small change to RTCSessionDescription and
RTCIceCandidate which would make the much more flexible:

[Constructor(optional Dictionary description)]
interface RTCSessionDescription {
             attribute RTCSdpType type;
             attribute DOMString  sdp;
};

In short the single constructor takes an Dictionary which is expected to
mimic its members, and the stringifier method is removed.


This has the advantages of being extremely powerful:

sd = new RTCSessionDescription();
sd.sdp = ...;
sd.type = ...;

sd = new RTCSessionDescription({sdp:"..."});
sd.type = ...;

sd = new RTCSessionDescription({type:"answer", sdp:"..."});

sd = new RTCSessionDescription(JSON.parse(some_json_string));

sd2 = new RTCSessionDescription(sd);

and in the other direction

jsonified_sd = JSON.stringify(sd);


There's some precedence in using a constructor like this in some of the
base Event classes.


Regards,
Tommy
