Version:

2.2.0

Based on the work of John Vlissidles in his book 'Pattern Hatching' an article by Douglas Schmidtt on double-checked locking and policy templates described by Andrei Alexandrescu.

This is a thread safe wrapper for creating Singleton classes. The synchronization method and instantiation methods can be changed easily by specifying different policy implementations as the templates parameters.

 // Most common Singleton
 Singletion<LonesomeType>

 // Singleton that uses static storage 
 Singletion<LonesomeType, StaticInstantiation>

 // Single-threaded singleton that uses static storage (Meyers-like)
 Singletion<LonesomeType, LocalStaticInstantiation, NotLocked>
