29 // GEANT 4 class header file
30 //
31 // Class Description:
32 // This function implements a simplified "garbage collection" mechanism
33 // for G4-MT model. Objects are registered when created on the heap and they
34 // will be deleted at the end of
35 // the program (like they would be if marked as "static").
36 //
37 // Limitation:
38 // The registered object, should not
39 // contain any G4ThreadLocal data member. Note that in general,
40 // if object is to be thread-private it is unnecessary to mark
41 // any data-member as G4ThreadLocal.
42 //
43 // Performance issues:
44 // This function uses G4ThreadLocalSingleton that on its own uses
45 // locks and mutexes. Thus its use should be limited to only when
46 // really necessary.
47 //
48 // Example:
49 // class G4SharedByThreads {
50 // void calledByThreads() {
51 // G4Something* anObject = new G4Something;
52 // G4AutoDelete::Register( anObject );
53 // }
54 // };
55 //
56 // History:
57 // 28 October 2013: A. Dotti - First implementation
