Object wrapping a reference to a remote drb object.

Method calls on this object are relayed to the remote object that this object is a stub for.

_load(s)

Unmarshall a marshalled DRbObject.

If the referenced object is located within the local server, then the object itself is returned. Otherwise, a new DRbObject is created to act as a stub for the remote referenced object.

# File lib/drb/drb.rb, line 1021
def self._load(s)
  uri, ref = Marshal.load(s)

  if DRb.here?(uri)
    obj = DRb.to_obj(ref)
    if ((! obj.tainted?) && Thread.current[:drb_untaint])
      Thread.current[:drb_untaint].push(obj)
    end
    return obj
  end

  self.new_with(uri, ref)
end
new(obj, uri=nil)

Create a new remote object stub.

obj is the (local) object we want to create a stub for. Normally this is nil. uri is the URI of the remote object that this will be a stub for.

# File lib/drb/drb.rb, line 1062
def initialize(obj, uri=nil)
  @uri = nil
  @ref = nil
  if obj.nil?
    return if uri.nil?
    @uri, option = DRbProtocol.uri_option(uri, DRb.config)
    @ref = DRbURIOption.new(option) unless option.nil?
  else
    @uri = uri ? uri : (DRb.uri rescue nil)
    @ref = obj ? DRb.to_id(obj) : nil
  end
end
new_with(uri, ref)

Creates a DRb::DRbObject given the reference information to the remote host uri and object ref.

# File lib/drb/drb.rb, line 1038
def self.new_with(uri, ref)
  it = self.allocate
  it.instance_variable_set(:@uri, uri)
  it.instance_variable_set(:@ref, ref)
  it
end
new_with_uri(uri)

Create a new DRbObject from a URI alone.

def self.new_with_uri(uri)
  self.new(nil, uri)

__drbref()

Get the reference of the object, if local.

Source: show | on GitHub 

# File lib/drb/drb.rb, line 1081
def __drbref
  @ref
end
__drburi()

Get the URI of the remote object.

def __drburi
  @uri
end
_dump(lv)

Marshall this object.

The URI and ref of the object are marshalled.

# File lib/drb/drb.rb, line 1053
def _dump(lv)
  Marshal.dump([@uri, @ref])
end
method_missing(msg_id, *a, &b)

Routes method calls to the referenced remote object.

# File lib/drb/drb.rb, line 1101
def method_missing(msg_id, *a, &b)
  if DRb.here?(@uri)
    obj = DRb.to_obj(@ref)

    return obj.__send__(msg_id, *a, &b)
  end

  succ, result = self.class.with_friend(@uri) do
    DRbConn.open(@uri) do |conn|
      conn.send_message(self, msg_id, a, b)

    bt = self.class.prepare_backtrace(@uri, result)
    result.set_backtrace(bt + caller)
    raise result
  end
end
respond_to?(msg_id, priv=false)

Routes respond_to? to the referenced remote object.

def respond_to?(msg_id, priv=false)
  case msg_id
