//
|
|
// 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 );
|
|
// }
|
|
// }
