Detailed Description

A template singleton.

This template class can be used to implement the singleton pattern. The underlying object will be destroyed automatically when the process exits.

For a singleton whose lifetime is bounded by the simulation run, not the process, see SimulationSingleton.

To force your class ExampleS to be a singleton, inherit from Singleton:

class ExampleS : public Singleton<ExampleS> { ... };

Then, to reach the singleton instance, just do

ExampleS::Get ()->...;

Note: If you call Get() again after the object has been destroyed, the object will be re-created which will result in a memory leak as reported by most memory leak checkers. It is up to the user to ensure that Get() is never called from a static variable finalizer.
