Detailed Description

template<template< class > class TypeEvaluator, class TupleType>
class Dune::ForEachType< TypeEvaluator, TupleType >

Helper template to clone the type definition of a tuple with the storage types replaced by a user-defined rule.

Suppose all storage types A_i in a tuple define a type A_i::B. You can build up a pair consisting of the types defined by A_i::B in the following way:

template <class A>
struct MyEvaluator {
  typedef typename A::B Type;
};
 
typedef ForEachType<MyEvaluator, ATuple>::Type BTuple;

Here, MyEvaluator is a helper struct that extracts the correct type from the storage types of the tuple defined by the tuple ATuple.
