The core idea is to initialize objects an share them as often as possible for reuse. Mostly the flyweight pattern can be seen in desktop UI implementation (GUI). In Java Swing, for instance, the JTable rendering uses this pattern, to reduce the computation needed for painting. /golang-singleton-pattern/ Sun, 15 Oct 2017 17:47:18 +0000 /golang-singleton-pattern/ There are a number of design patterns I am using on daily bases, and one of them is the Singleton pattern. In Golang penalties in performance are not so harsh as in other languages, if the application is not designed and written to perform with minimal CPU and memory footprint. I’m trying to keep my implementations as performing as possible, but sometimes explicit benchmarks can revile the details. The singleton pattern is widely used in Object Oriented languages, and it is well worth to use it in golang.
