Overview
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 TimerIdConv in rdb/timeridconv.rb and DRbNameIdConv in sample/name.rb in the full drb distribution.

Instance Method Details
#to_id(obj)

This implementation returns the object's __id__ in the local object space.
# File 'lib/drb/drb.rb', line 380
def to_id(obj) obj.nil? ? nil : obj.__id__ end
#to_obj(ref)
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.
# File 'lib/drb/drb.rb', line 372
def to_obj(ref) ObjectSpace._id2ref(ref) end
