source: code/branches/core5/src/libraries/core/ScopedSingletonManager.cc @ 5925

Last change on this file since 5925 was 5867, checked in by rgrieder, 15 years ago

Modified Scoped Singleton concept: Derive from Singleton normally, but place an important pre-main() instruction in the source file: ManageScopedSingleton(className, scope) (it's a macro).
This causes the Singleton to be created and destroyed with the Scope. Thus if a Singleton c'tor throws, it is much easier to react accordingly.
