namespace singleton_pattern

Namespace for the Singleton pattern.

class Singleton

#include <singleton.hpp>

A class implementing the Singleton design pattern.

The Singleton class ensures that only one instance of the class exists and provides a global point of access to that instance. This is achieved using a private constructor and a static method for instance retrieval.

Public Functions

void doSomething()

An example method to demonstrate Singleton usage.

Example method that demonstrates the Singleton’s behavior.

This method serves as an example of how the Singleton can provide functionality via its single instance.

This method serves as an example of how to interact with the Singleton instance. It performs a specific action, such as printing a message.

Public Static Functions

static Singleton &getInstance()

Retrieves the single instance of the Singleton class.

Retrieves the Singleton instance.

This method returns a reference to the single instance of the Singleton. The instance is created lazily and is guaranteed to be thread-safe in C++11 and later.

This static method ensures that only one instance of the Singleton class exists throughout the program’s lifecycle. The instance is lazily initialized on its first use, and its lifetime is automatically managed by the program.

The static local variable ensures thread safety in C++11 and later standards.

Returns:

Singleton& A reference to the Singleton instance.

Returns:

A reference to the Singleton instance.
