One requires creating a new tailored object, the other adapts itself to any object un-intrusively.
So it's pretty obvious global<int>.get() is better, and not just a matter of taste.
Let us discuss that: 1) Boost::global example: typedef boost::global<int> global_Int; global_int.get() = 5; // getting the global int 2) Boost::Singleton example: typedef boost::Singleton<int> global_Int; global_Int::Instance() = 5; I really do not understand the appreciable advantage of the 1) over the 2) and vice versa.:confused: The only thing I could say is that "get" is shorter word than "Instance", isn't it? -- View this message in context: http://old.nabble.com/-Boost.utility--tp27309940p27324932.html Sent from the Boost - Dev mailing list archive at Nabble.com.
