for example:
youObject.prototype={
QueryInterface: function(aIID) {
if ( !aIID.equals(Components.interfaces.nsISupports)) {
throw Components.results.NS_ERROR_NO_INTERFACE;
}
return this;
}
}
let you pass the JS Object as nsISupports parameter to your interface function (Tanks to XPConnent).
Unless you want save a JS object reference in your XPCOM component the declaration above is useless!!!! If you want do something with you JS Object in XPCOM function it must implement a interface other than nsISupports.
If you pass a string or a JS Array to XPCOM interface you can find information how to do this directly without QueryInterface blah blah on Mozilla web site (I don't remember the link of page of interest... sorry :'( )

Hi All,
I would like to pass a _javascript_ object to an XPCOM interface.
What type should I use for the parameter?
Similarly I would like to use the type as a return type of a method.
See an example:
interface nsIMyInterface : nsISupports
{
void MyFunc(in nsISupport aJavaScriptObject);
nsISupport GetJSObject();
}
Within the example I have used nsISupports as a type. Not sure
if it's correct...
Thanks for any ideas!
