![alt text](./etc/monostate.png "MonoState")
Use the Monostate pattern when
* The same state must be shared across all instances of a class.
* Typically this pattern might be used everywhere a Singleton might be used. Singleton usage however is not transparent, Monostate usage is.
* Monostate has one major advantage over singleton. The subclasses might decorate the shared state as they wish and hence can provide dynamically different behaviour than the base class.
## Typical Use Case
* the logging class
* managing a connection to a database
* file manager
