ISSUE-7: FrameRequestCallback interface should be designated as Callback=FunctionOnly

FrameRequestCallback interface should be designated as Callback=FunctionOnly

State:

CLOSED

Product:

Request Animation Frame

Raised by:

Jatinder Mann

Opened on:

2011-06-01

Description:

Unless explicitly specified with a Callback=FunctionOnly statement in the IDL, we will be allowing objects to be registered as callbacks, like so:

E.g.
var obj = new Object();
obj.handleEvent = function (event) { alert (‘hello, world!’); }
window.requestAnimationFrame(obj);

Registering objects as callbacks is somewhat uncommon and may not be what we want. The Geolocation PositionCallback function, http://dev.w3.org/geo/api/spec-source.html, also explicitly calls out that the callback be a function only.

The change would look like so:

[Callback=FunctionOnly, NoInterfaceObject]
interface FrameRequestCallback {
void sample(in DOMTimeStamp time);
};
