[v8-users] intercepting all property accesses on an object

[Jey Kottalam]

I have a constructor Foo:

function Foo() { this.first = 1; }
Foo.prototype = { second: 2 };

and I want to intercept all property accesses of instances of Foo. I'm
trying to do this by creating an ObjectTemplate with a
NamedPropertyHandler and simulating the effect of "new Foo()" on an
object created from this ObjectTemplate. This almost works, except I
can't figure out how to apply Foo.prototype to the newly constructed
object.


Here's an example that demonstrates the problem:

function Foo() { this.first = 1; }
Foo.prototype = { second: 2 };
Foo = TracedObject(Foo);

var t = new Foo();
log(t.first + "\n");
log(t.second + "\n");


The output is:

1
undefined


TracedObject is implemented as: http://gist.github.com/10136


How do I correctly simulate the effect of new Foo() on the object
created from my ObjectTemplate?

Thanks,
