Sorry to ask you another problem, but could you try another test?
The following code shows a small example, which comes from a real program of mine. I
have changed my old out-of-line code to use boost local. Note that in practice there are many different types which implement my 'vars' interface (getMax/getMin/setMax/setMin).
#include <iostream> #include <string> #include <vector> #include <algorithm> #include "local/boost/local/function.hpp"
template<typename T> struct Var { void setMax(int i) {} void setMin(int i) {} int getMax() { return 0; } int getMin() { return 0; } };
template<typename T> void squeeze_vars_local(std::vector<T>& vec, int i) {
void BOOST_LOCAL_FUNCTION_PARAMS_TPL(T& t, bind i) { t.first.setMax(t.second.getMax() - i); t.second.setMin(t.first.getMin() + i); } BOOST_LOCAL_FUNCTION_NAME(squeeze);
std::for_each(vec.begin(), vec.end(), squeeze); }
int main(void) { std::vector<std::pair<Var<int>, Var<double> > > v; squeeze_vars_local(v,2); }
In the past I tried turning this into phoenix code, and failed. I'd be genuinely interested to know what it would look like as a phoenix function.
Here's the phoenix functions rendition of that: http://pastebin.com/QWnHiKkv Regards, -- Joel de Guzman http://www.boostpro.com http://boost-spirit.com
