Singleton Implementation

This script creates a unique instance of classes that uses Singleton as their metaclass. Used as a metaclass, Singleton replaces a class with a unique class instance. Any subsequent calls to the class's constructor will result in an exception, as the constructor is overwritten immediately after...

This script is an implementation of the singleton without using the __new__ class but by implementing the __call__ method in the metaclass.

This script contains a class that shows how to implement the singleton pattern in Python. A singleton is a class that makes sure only one instance of it is ever created. Typically such classes are used to manage resources that by their very nature can only exist once.

Intent: Ensures a class only has one instance and provide a global point of access to it [1].Motivation: It's important for some classes to have exactly one instance. For example, it can be desirable to have only a single instance of a GUI. With a MATLABdlT« GUIDE built GUI, the driver or main...
