We use Loki::Singleton (full policy based implementation of the singleton pattern). http://sourceforge.net/projects/loki-lib/ Marius -----Original Message----- From: boost-bounces@lists.boost.org [mailto:boost-bounces@lists.boost.org] On Behalf Of Medland, Thomas M Sent: Tuesday, May 08, 2007 1:09 PM To: boost@lists.boost.org Subject: [boost] Boost singleton Hi, I have just moved company and in my old company I used to use a RogueWave singleton class. I was looking to use the boost singleton class. However after looking at the implementation I saw there was no private default copy constructor or assignment operator. Does this not mean that I could create multiple instances of my singleton via assignment or some other form of copying? I saw some discussion of a better singleton representation in boost and I was wondering what the status of this was, and I was also wondering what other people use for their singletons?
