Question

What is the equivalent of:

AtomicReference<SomeClass> ref = new AtomicReference<SomeClass>( ... );

but without the synchronization cost. Note that I do want to wrap a reference inside another object.

I’ve looked at the classes extending the Reference abstract class but I’m a bit lost amongst all the choices.

I need something really simple, not weak nor phantom nor all the other references besides one. Which class should I use?

Answer 1

If you are simply trying to store a reference in an object. Can’t you create a class with a field, considering the field would be a strong reference that should achieve what you want

You shouldn’t create a StrongReference class (because it would be silly) but to demonstrate it

public class StrongReference{
  Object refernece;

  public void set(Object ref){
    this.reference =ref;
  }
  public Object get(){
    return this.reference;
  }

}
