class DRb::DRbIdConv

Parent:: Object

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

to_id(obj) Show source

# File lib/drb/drb.rb, line 373
def to_id(obj)
  case obj
  when Object
    obj.nil? ? nil : obj.__id__
  when BasicObject
    obj.__id__
  end
end

Convert an object into a reference id.

This implementation returns the object's __id__ in the local object space.

to_obj(ref) Show source

# File lib/drb/drb.rb, line 365
def to_obj(ref)
  ObjectSpace._id2ref(ref)
end

Convert an object reference id to an object.

This implementation looks up the reference id in the local object space and returns the object it refers to.
