Pragmatic: Avoid the singleton pattern.
Singleton pattern, no problem there.
What is an efficient way to implement a singleton pattern in Java?
The singleton pattern solves problems like.
If used for the purpose it was intended for, you will gain extreme benefits from the Singleton pattern.
The singleton pattern is an important pattern in many programming languages.
Let's start with what we presumably already know: The Singleton pattern, the Factory pattern, etc;
The Singleton Pattern ensures a class has only one instance, and provides a global point of access to it.
I think the confusion is caused by the fact thatpeople don't know the real application of the Singleton pattern.
Under this perspective, the singleton pattern is just a kind of service locator, e.g. Model. getInstance().
If you can answer"yes" to thequestions below regarding your specific use case, the singleton pattern can yield some practical benefits.
The singleton pattern is used to ensure that a class has only one instance, and to provide a global point of access to it.
It might be suggested that in most cases where you use a static variable,you really want to be using the singleton pattern.
The Singleton pattern ensures that only one instance of a class will be created and provides a global point of access to it.
Once you outlaw calls to getInstance(),you have effectively tossed out the one useful difference between the Singleton pattern and an ordinary reference.
The singleton pattern is a fully paid up member of the GoF's patterns book, but it lately seems rather orphaned by the developer world.
The problem with global states is that sometimes what makes sense as global in a simpler context, needs to be a bit more flexible in a practical context,and this is where the singleton pattern becomes useful.
What i'm talking about(particularly when i say"capital-S Singleton")is the GoF's Singleton pattern, which embeds that single global instance in the class itself, exposes it via a getInstance or similarly named method, and prevents the existence of a second instance.
C++ Singleton design pattern.
The singleton design pattern describes how to solve such problems.
Singleton is not a pattern to wrap globals.
You can document it's not the case, or protect against it(singleton/factory pattern)- but that's extra work, and therefore an additional cost.
A singleton is a design pattern that allows only one instance of your class to be created, and this can be accomplished by using a private constructor.
Every time you want to use a singleton, try to consider why you are doing it, and what are the benefits and negatives of using this pattern.
My answer was meant to be a short list of the'anti patterns' that occur from bad Singleton usage.
I'm noticing that these days, I'm using Singletons a lot, and I'm worried that I might be abusing the design pattern myself, and running deeper and deeper into a bad-practice kind of habit.
