You could use the singleton pattern, but this pattern is, a) very difficult to get right, b) almost always used unnecessarily. Why do you want to do this? — Marcelo Cantos

@Codenotguru: your question title is rather generic. You should edit your question and make it more specific. — outis

Singleton pattern may become evil, there are many points that you should consider, on the surface it is the simplest pattern, but if you dig deeper it is dangerous. — baris.aydinoz
