Detailed Description

For instance the following code prints all fields of the message to std::cout

struct MessageDumper: public FixFieldsFunctor { void operator()(int tag, const Engine::AsciiString& value, int role) { std::cout << tag << '=' << value.data() << std::endl; } };

FIXMessage* msg; // fill it in MessageDumper dumper; msg->apply(dumper);
