Hello mpl experts,
I'm trying to initialize the elements of an array using rules defined in a list of structures. The code below illustrate what I'm trying to achieve.
The problem I have with this code is that the First_Descriptor structure contain this index member that will be used to access the right item of the array. This is not nice because it force the writer of this structure to deal with implementation details. Is there a way to get rid of this index typedef in the *_Descriptor structures by using another construct from the mpl that would generate it ?
The easiest thing to do is just to embed the index as a data member in the Initializer object, which can be stateful. Just bump the index each time the Initializer is invoked. HTH, Dave -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
