Hi,

I was trying to identify the classes in a give file at the run time. the following is the code i used.
sc, ec = [], []
ObjectSpace.each_object(Class) { |c| sc << c }
require 'Roman.rb'
ObjectSpace.each_object(Class) { |c| ec << c }
new_classes = ec - sc
puts new_classes
sc, ec = [], []
 ObjectSpace.each_object(Class) { |c| sc << c }
 require 'Roman1.rb'
 ObjectSpace.each_object(Class) { |c| ec << c }
 new_classes = ec - sc
puts new_classes
 
Both roman.rb and roman1.rb has the same class Roman.
the first time i print the new_classes i can see the Roman class in the output but the second one does not print because the class Roman is arleady read previously.

is there a way i can over come this problem and identify the Roman class twice.


Thanks,
Navya.
