// GEANT 4 class header file
//
// Class Description:
// This function implements a simplified "garbage collection" mechanism
// for G4-MT model. Objects are registered when created on the heap and they
// will be deleted at the end of
// the program (like they would be if marked as "static").
//
// Limitation:
// The registered object, should not
// contain any G4ThreadLocal data member. Note that in general,
// if object is to be thread-private it is unnecessary to mark
// any data-member as G4ThreadLocal.
//
// Performance issues:
// This function uses G4ThreadLocalSingleton that on its own uses
// locks and mutexes. Thus its use should be limited to only when
// really necessary.
//
// Example:
// class G4SharedByThreads {
// void calledByThreads() {
// G4Something* anObject = new G4Something;
// G4AutoDelete::Register( anObject );
// }
// };
//
// History:
// 28 October 2013: A. Dotti - First implementation
