In this example, the ClassicSingleton class maintains a static reference to the lone singleton instance and returns that reference from the static getInstance() method.Here, ClassicSingleton class employs a technique known as lazy instantiation to create the singleton; as a result, the singleton ...

QI read your column in theAugust 2002issue ofMSDN Magazineand found it very helpful. My problem is similar to your delegates example. I pass a C# delegate into unmanaged C++, and C++ makes the callback whenever it needs to. However, one of the members in the signature of the callback ...
接受ReSharper的建议不会毁掉这个Singleton。 Singleton是一种设计模式,用于确保一个类只有一个实例,并提供一个全局访问点。在实现Singleton模式时,需要注意线程安全性和实例化的时机。 ReSharper是一个用于代码重构和优化的工具,它可以提供一些建议来改进代码的质量和性能。在某些情况下,ReSharper可能会建议对代码进行修改...
