Converting C++ class to JSON

Question

I\'d like to create a JSON string containing the instance variables of my class.

For example,

class Example {  
    std::string string;  
    std::ma

JSON Spirit would allow you to do it like so:

Object addr_obj;

addr_obj.push_back( Pair( "house_number", 42 ) );
addr_obj.push_back( Pair( "road",         "East Street" ) );
addr_obj.push_back( Pair( "town",         "Newtown" ) );

ofstream os( "address.txt" );
os.write( addr_obj, os, pretty_print );
os.close();

Output:

{
    "house_number" : 42,
    "road" : "East Street",
    "town" : "Newtown"
}

The json_map_demo.cpp would be a nice place to start, I suppose.
