- emitter < EventEmitter> |
emitter or timer to be added to the domain
Explicitly adds an emitter to the domain. If any event handlers called by the emitter throw an error, or if the emitter emits an ‘error’ event, it will be routed to the domain’s ‘error’ event, just like with implicit binding.
This also works with timers that are returned from setInterval() and setTimeout(). If their callback function throws, it will be caught by the domain ‘error’ handler.
If the Timer or EventEmitter was already bound to a domain, it is removed from that one, and bound to this one instead.
