Does jQuery live use setInterval?

Is the jQuery live method using setInterval to update the events?

Does this affect performance?

Based on this blog as a resource, it appears that jQuery.live() works by attaching the events to the document. Then, when an event is triggered (such as by a click), the event bubbles up to the document level - at which point it is compared against all the live event handlers. If it matches a live event handler, it fires the event for it.

This blog describes pretty well what's going on behind the scene.

live does not use setinterval but livequery does.

It seems it does NOT use SetInterval. I could be wrong.
