Re: [Boost-users] [bind] How to dereference _1 in a boost::bindexpression

Peter Barker: ...

void accept(TheClass& tc) { }

int main() { std::vector cont;

// Compile error - how to dereference _1 ??? std::for_each(cont.begin(),cont.end(),boost::bind(&accept,_1)); }

How can I dereference _1 so I can use the accept function?

With boost::bind, there's no easy way to dereference _1. You'd need template<class T> T& deref( T* p ) { return *p; } std::for_each( cont.begin(), cont.end(), boost::bind( accept, boost::bind( deref<TheClass>, _1 ) ) );
