How do I remove an event listener from an anonymous component?

Say I have an event listener tied to a component and I want to remove the event listener from the component so it can be garbage collected. The problem is I don't know what kind of object it is or what event listeners it has.

Basically how can I find out what event listeners an object has and how can I remove one or all of them?

  When you add the event listener mark it as a weak refernce by setting the last parameter as true. You no longer need to worry about removing it. I posted a longish answer here, so you may want to take a look.
