Singleton is a design pattern in object-oriented programming that restricts the instantiation of a class to only one object. This means that a singleton class can only have one instance created at any given time.
Key Characteristics:
1. Private Constructor:
A singleton class will have a private constructor to prevent external instantiation of the class.2. Static Instance:
The class will have a static member variable that holds the single instance of the class.3. Global Access Point:
The singleton class will provide a global access point to allow other classes to access its single instance.Common Uses:
1. Configuration Management:
Singleton pattern is often used in scenarios where there is a need for a single configuration manager instance to manage system configurations.2. Logging:
Another common use case is in logging frameworks where a single instance of a logger is used throughout the application.It is important to note that the singleton pattern should be used judiciously as it can introduce global state in an application, which can lead to tight coupling between classes and make the code harder to test and maintain. However, when used appropriately, the singleton pattern can be a powerful tool in managing resources efficiently in an application.
