I\'ve been using LazyReference class for a few years (not on a regular basis of course, but sometimes it is very useful). The class can be seen here. Credits go to Robbie Vanbrabant (class author) and
Recently I have been refactoring some of my C# code and I found a few double-checked locking practices taking place. I didn\'t know it was a bad practice back then and I really want to get rid of it.
The new machine model of C++11 allows for multi-processor systems to work reliably, wrt. to reorganization of instructions.
Does this code solve the double checked locking issue in Java? public class DBAccessService() { private static DBAccessService INSTANCE;
According to many, the somewhat common Double-Checked Locking idiom is broken for java unless you\'re running 1.5 or later and use the volati开发者_运维百科le keyword.
Imagine you have a static no-ar开发者_JAVA技巧gument method which is idempotent and always returns the same value, and may throw a checked exception, like so:

In C++ and the Perils of Double-Checked Locking, there\'s persudo code to implement the pattern correctly which is suggested by the authors. See below,
I heard and read a lot about singleton implementation approaches in C++, like Meyer, Phoenix, etc., but all of them seemed to have a problem in certain usage scenarios. So I came up with my own implem
In C#, the following code (from this page) can be used to lazily instantiate a s开发者_运维知识库ingleton class in a thread safe way:
