Detailed Description

The declaration of major parsing functions used e.g for (re)implementation of new extended properties see class Property These function also could be used in a different, much wider contex.

all of them have the semantic: StatusCode parse ( TYPE& result , const std::string& input ) where input is the input string to be parsed, and result is the the result of parsing

  const std::string        input = ... ;
  std::vector<std::string> result ;

  // parse the input
  StatusCode sc = parse ( result , input ) ;
  if ( sc.isFailure() )
  {
    // error here ...
  }
  std::cout << "vector size " << result.size() << std::endl ;
