Re: Is it necessary to call make_immutable in parent class?

Hi Stevan,

Thanks for your clarification.
This OO framework really helps a lot in my projects.

Thank you.

Justin,

You need to call make_immutable on all classes, as it only affects the local class and not the superclasses.

Hi,

I am new to Moose and I love this framework.
I have a question regarding to making class immutable.
Suppose I have a class hierarchy as below:

         A
        /
      B
    /   \
   C     D

B is the parent class of C and D.
A is the parent class of B.

Now I want to make class C immutable.

My question is "when I call C->meta->make_immutable(), does it apply to only the meta class of C or apply to all its parent classes (B,A) but within class C's namespace? In other words, after making class C immutable, will it introspect the structure of Class A and B when I create a new object? Do I need to call make_immutable for class B and A If I want to make Class C immutable?"

Thanks,
