Method: IOReactor#register

Defined in:
lib/mega/ioreactor.rb

#register(io, *args, &handler) ⇒ Object Also known as: add

Register the specified IO object with the reactor for events given as args. The reactor will test the given io for the events specified whenever #poll is called. See the #poll method for a list of valid events. If no events are specified, only :error events will be polled for.

If a handler is specified, it will be called whenever the io has any of the specified events occur to it. It should take at least two parameters: the io and the event.

If args contains any objects except the Symbols ‘:read’, ‘:write’, or ‘:error’, and a handler is specified, they will be saved and passed to handler for each event.

Registering a handle will unregister any previously registered event/handler+arguments pairs associated with the handle.
