Hi,
Assume that I have a custom type sequence S that has two operations, size<S>::value and element<S,I>::type (with whatever spelling).
What needs to be done to adapt S into a conforming MPL or Fusion sequence?
In a perfect world, the answer would not require the inclusion any MPL or Fusion headers and would consist of three specializations. ;-)
Well, if it's an MPL sequence it's a fusion sequence, IIUC. So you need to decide which sequence to model http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/concepts.html According to http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/forward-sequence... you can make a forward sequence with 5 specializations. Please let me know if that's not enough information. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
