Boost.Reflect - Simple Reflection Library

The Boost Reflect library provides a means to describe the interface of a class or struct to provide compile-time and run-time reflection.

Some of the useful features provided by the Reflect library include:

• boost::reflect::any - a class that can contain any object that implements Interface.
• Use visitors to create dynamic interfaces.
  • RPC client/server stubs
  • Command Line Interface
  • Scripting Interfaces
  • Asynchronous Actors

Example: Simple Command Line Calculator

An example of how to create a command line calculator can be found in the examples directory.

#include <boost/reflect/any.hpp>

struct calculator {
    calculator():result_(0){}
    double add( double v ) { return result_ += v; }
    double sub( double v ) { return result_ -= v; }
    double result()        { return result_;      }

    private:
        double result_;
};

BOOST_REFLECT_ANY( calculator, (add)(sub)(result) )

int main( int argc, char** argv ) {
  boost::reflect::any_ptr<Calculator> s( new CalculatorService() );
  printf( "Result: %f\n", s->result() );

  cli  m_cli(s);

  std::string line;
  std::string cmd;
  std::string args;

  while( true ) {
      std::cerr << "Enter Method: ";
      std::getline( std::cin, line );
      cmd = line.substr( 0, line.find('(') );
      args = line.substr( cmd.size(), line.size() );
      std::cerr << m_cli[cmd](args) << std::endl;
  }

  return 0;
}

Output

add        double(double)
sub        double(double)
result     double()const

Enter Method: add(5)
5
Enter Method: sub(3)
2
Enter Method: result()
2
