Destructors?

[Anthony]

Is there a concept of an object destructor in JS.Class? I need to
delete an object and run some logic in the process.

You can't delete an object in Javascript*, and I don't think that it
could be easily simulated.

Can't you just use a classic method then remove every reference to the
instance ?

* Even the delete operator does not delete the object. You must not
use it as the c++ delete operator.

Hmm I guess I need to read up on the delete keyword.

What I need to do is re-instantiate a JS.Class and replace the
assignment. This is what I'm doing for now:

var myObj = new Foo.Bar.MyObj();
// ... use it for a while... then eventually I need to reconstruct
it...
myObj.destroy() // My own destructor method as you suggested
myObj = new Foo.Bar.MyObj();

Hi Anthony,
you don't have to care about zombie-objects as the Javascript garbage
collector will remove everything that is not referenced anymore.

foo = new Bar();
foo = null; or foo = new Bar();

should be enough. The old instance will be removed if you don't have
any other references pointing to it.

Thank you =)
