DRb::DRbIdConv

Class responsible for converting between an object and its id.

This, the default implementation, uses an object's local ObjectSpace __id__ as its id. This means that an object's identification over drb remains valid only while that object instance remains alive within the server runtime.

For alternative mechanisms, see DRb::TimerIdConv in drb/timeridconv.rb and DRbNameIdConv in sample/name.rb in the full drb distribution.

Public Instance Methods

Convert an object into a reference id.

def to_id(obj)
  case obj

    obj.nil? ? nil : obj.__id__
  when BasicObject
    obj.__id__
  end
end
to_obj(ref) click to toggle source

Convert an object reference id to an object.
