Static diagram

Description :

Type :  Cr  (Creational)
Intent : Ensure a class only has one instance, and provide a global point of access to it.
Applicability : Use the Singleton pattern when :
- there must be exactly one instance of a class, and it must be accessible to clients from a well-known access point.
- when the sole instance should be extensible by subclassing, and clients should be able to use an extended instance without modifying their code.
