I'm using the Boost.Range 2.0 library (Boost version 1.43.0), and I was looking for metafunctions to use in conjunction with boost::enable_if. I wasn't able to find anything akin to "is_range" and/or "is_range_of" in Boost.Range or in Boost.TypeTraits.
Did I overlook something? Is there an easy way to get this effect?
You may not have overlooked anything, but normally using Boost.ConceptCheck with the appropriate RangeConcept achieves a solution to most problems, but admittedly does not provide a solution to disambiguate overloads in enable_if expressions.
I did find an email in the archives with an implementation of this functionality: http://lists.boost.org/Archives/boost/2007/08/125851.php That implementation works for me. Is there a reason they have not been included?
This contribution has only been received recently and before it can become part of Boost.Range I need to ensure correctness and portability across compilers. It also needs tests and documentation to meet the completeness expected of a high quality Boost library. I have also been very busy! I am very excited about this contribution, and if all goes smoothly then it will be in the next Boost release. Thanks for any guidance,
Duncan
You can help by trying out the code on the list and informing me of the compiler and platform you are using ;-) Thanks, Neil Groves
