Method: ZMQMachine::Socket::Rep#on_attach

Defined in:
lib/zm/sockets/rep.rb

#on_attach(handler) ⇒ Object

Attach a handler to the REP socket.

A REP socket must alternate between recv.send (i.e. it cannot receive twice in a row without an intervening send). This socket expects its handler to implement at least the #on_readable method. This method will be called whenever a request arrives.

For error handling purposes, the handler must also implement #on_readable_error.

Raises:

  • (ArgumentError)
