Method: EventMachine::Connection#unbind

Defined in:
lib/em/connection.rb

#unbind ⇒ Object

called by the framework whenever a connection (either a server or client connection) is closed. The close can occur because your code intentionally closes it (using #close_connection and #close_connection_after_writing), because the remote peer closed the connection, or because of a network error. You may not assume that the network connection is still open and able to send or receive data when the callback to unbind is made. This is intended only to give you a chance to clean up associations your code may have made to the connection object while it was open.

If you want to detect which peer has closed the connection, you can override #close_connection in your protocol handler and set an @ivar.

Examples:

Overriding Connection#close_connection to distinguish connections closed on our side


class MyProtocolHandler < EventMachine::Connection

  # ...

  def close_connection(*args)
    @intentionally_closed_connection = true
    super(*args)
  end

  def unbind
    if @intentionally_closed_connection
      # ...
    end
  end

  # ...

end
