[Ironruby-core] Adding a finalizer to a ruby object

Hi

How do I add a finalizer to a ruby object?

I''ve tried using ObjectSpace and define_finalizer.
But the proc never got executed when I called ObjectSpace.garbage_collect
Calling System::GC.collect had the same outcome

and implementing a Finalize method doesn''t seem to have any effect
either

class MyClass

  def Finalize
    puts "in Finalize"
  end

  def finalize
    puts "in lower finalize"
  end

end

MyClass.new
System::GC.collect System::GC.max_generation,
System::GCCollectionMode.forced
#ObjectSpace.garbage_collect

Thanks

Garbage collection in Ruby is kind of tricky.

What about using a proc, or block and running finalize after yield or
proc.call?

[Ironruby-core] Adding a finalizer to a ruby object

I specifically wanted to find a counterpart for this C#

public class SomeClass {

   private object _unmanagedResource;

   public SomeClass(object unmanagedResource){
     _unmanagedResource = unmanagedResource;
   }

  ~SomeClass(){
    _unmanagedResource.Cleanup();
    _unmanagedResource = null;
  }
}

I was writing about the dispose pattern and wanted to include a full
counterpart implementation with a finalizer for unmanaged resources.

[Ironruby-core] Adding a finalizer to a ruby object

oh if that is the case can they also get back to me with overriding an
indexer (http://ironruby.codeplex.com/WorkItem/View.aspx?WorkItemId=3392)?
I think that would result in a complete chapter with regards to CLR interop.

Thanks a lot :D

[Ironruby-core] Adding a finalizer to a ruby object

We don?t support finalizers yet, but it shouldn?t be too much work to make
ObjectSpace#define_finalizer work with Ruby objects. We might also consider
providing some means to override CLR Finalize method.
