I'm trying to do...
EventEmitter = require('events').EventEmitter
events = new EventEmitter()
events.emit.apply(null, ['eventname', 'arg1', 'arg2', 'arg3'])
...but it doesn't seem to work or throw an error, any help?
Problem courtesy of: boom
On Apply method you need inform two arguments:
A valid scope (what value will be the "this" inside the method) and the argument array.
I think the
emit() function of the EventEmitter is expecting
this to be an actual EventEmitter object. The following seems to work if you pass in the
events.emit.apply(events, ['eventname', 'arg1', 'arg2', 'arg3'])
Though at this point, might as well just call
emit('eventname', 'arg1', 'arg2', 'arg3')
I am guessing the
emit() method is looping over an internal list of registered events to see if there is a matching one. Not sure if this helps, just something I came across today working with events...
