SINGLETON Meaning and
Definition
-
A singleton, in computer science, refers to a design pattern that restricts the instantiation of a class to a single object. It is a commonly used approach to ensure that only one instance of a class is created for the entire lifecycle of an application.
In this context, a singleton is often implemented by creating a static instance within the class itself, along with a private constructor that prevents any other instances from being created. The class's static instance is then accessed through a getter method, allowing other parts of the program to interact with the singleton.
The purpose of using a singleton is to provide a global point of access, as well as to centralize control and coordination of a specific resource or functionality. It can be useful when there is a need for a shared resource across different parts of an application, and maintaining consistency and avoiding conflicts is crucial.
Singletons are commonly employed in scenarios such as managing database connections, logging, configuration settings, or thread pools. By allowing just one instance of a class to exist, singletons can help improve performance, reduce memory consumption, and simplify code maintenance.
However, it is important to note that the singleton pattern also has drawbacks, such as potential tight coupling and difficulties in unit testing. Careful consideration should be given to its usage, as the singleton pattern is not suitable for all situations.
