jsPlumb.fire("jsPlumbDemoLoaded", instance); what is this?

Question

When reading the demo code of jsPlumb, I saw this statement is called in several demos.

jsPlumb.fire("jsPlumbDemoLoaded", instance);

However I could not find the API for jsPlumb.fire(). And I don't know where the first parameter is defined.

Could anyone help? Thanks!

The same statement had me a little confused too.

It seems to be calling an undocumented EventGenerator method. The first argument is the name of an event. The only event that seems to be set up by default is "ready". So the fire method checks if an event called "jsPlumbDemoLoaded" exists, then, when it's not found, the method returns.

My guess is it's a leftover from an older version.
