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
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;
}
