nsIVariant Interface Reference

import "nsIVariant.idl";

Inheritance diagram for nsIVariant:

nsISupports nsIWritableVariant nsVariant

List of all members.

Detailed Description

XPConnect has magic to transparently convert between nsIVariant and JS types. We mark the interface [scriptable] so that JS can use methods that refer to this interface. But we mark all the methods and attributes [noscript] since any nsIVariant object will be automatically converted to a JS type anyway.
