High Performance Dynamic Typing in C++ (View in Weblogs)

Summary
Inspired by Kevlin Henney's boost::any variant type I have written a high performance alternative called cdiggins::any.

I've come up with what so far appears to be a a very robust and extremely fast alternative to boost::any. My preliminary tests have shown a speed up of 40x under certain circumstances.

I have published my code along with a brief article at here at CodeProject.com.

I wrote this type so that I could have top performance in dynamically typed code produced by the Heron to C++ translator I am writing. Hopefully others will find it useful as well.

1. CodeProject link is broken - should be http://www.codeproject.com/cpp/dynamic_typing.asp ?

2. Code shown in the article claims to be under the Boost license rather than public domain - can you clarify?

cheers

It started off as public domain, but then Pablo Aguilar made some changes, and we decided to copy the existing boost::any interface. Because we have lifted the boost interface almost verbatim, we are bound by the boost license. We are plannining on submitting the new version to Boost.

Sorry, for any inconvenience.
