Detailed Description

template<template< int > class Operation, int first, int last>
class Dune::ForLoop< Operation, first, last >

A static loop using TMP.

 The ForLoop takes a 
   @code template<int i> class Operation \endcode
 template argument with a static apply method
 which is called for i=first...last (first<=last are int template arguments).
 A specialization for class template class Operation for i=first
 or i=last is not required. The class Operation must provide a
 static void function apply(...). Arguments (as references) 
 can be passed through the ForLoop to this function 
 (up to 5 at the moment).

 It is possible to pass a subclass to the ForLoop 
 (since no specialization is needed).

 Example of usage:
 @code 

template<class Tuple> struct PrintTupleTypes { template <int i>=""> struct Operation { template<class Stream> static void apply(Stream &stream, const std::string &prefix) { stream << prefix << i << ": " << className<typename tuple_element<i, Tuple>::type>() << std::endl; } }; template<class Stream> static void print(Stream &stream, const std::string &prefix) { // cannot attach on-the-fly in the argument to ForLoop<..>::apply() since // that would yield an rvalue std::string extended_prefix = prefix+" ";

stream << prefix << "tuple<" << std::endl; ForLoop<Operation, 0, tuple_size<Tuple>::value-1>:: apply(stream, extended_prefix); stream << prefix << ">" << std::endl; } };

Note
Don't use any rvalues as the arguments to apply().

Rvalues will bind to const-references, but not to references that are non-const. Since we do want to support modifiable arguments to apply(), we have to use non-const references as arguments. Supporting const references as well would lead to an insane number of overloads which all have to be written more-or-less by hand.

Examples of rvalues are: literals (1.0, 0, "huhu"), the results of functions returning an object (std::make_pair(0, 1.0)) and temporary object constructions (std::string("hello"));
