36 // The SbPimplPtr<> class is loosely based on the boost::pimpl_ptr<>-
37 // proposal of 2005 by Asger Mangaard.
38 //
39 // It is reimplemented here as separate classes, not with policy-based
40 // templates, because we still try to support compilers that don't support
41 // template templates (e.g. Visual C++ 6).
42 //
43 // See also SbLazyPimplPtr<>, our implementation of the lazy-creation policy.
