Constructor Details

#initialize(host, port, obj) ⇒ ProxyNobject

host: the hostname of the server to push obj to port: the port number of the server to push obj to obj: the obj to store over the network

ex:

# this will create a new ProxyNobject, then put it to the specified server
ProxyNobject.new('localhost', 1234, <object>)

def initialize(host, port, obj)
  @socket = TCPSocket.new(host, port)
  obj_bytes = Marshal.dump(obj)

  @socket.send([obj_bytes.length].pack('Q>'), 0)
  @socket.send(obj_bytes, 0)
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, **kwargs, &block) ⇒ Object
