◆ split_string() [1/2]

Vector< std::string > oomph::StringConversion::split_string	(	const std::string &	s,
		char	delim
	)

Split a string, s, into a vector of strings where ever there is an instance of delimiter (i.e. is delimiter is " " will give a list of words). Note that mutliple delimiters in a row will give empty strings. Return by value.

Split a string, s, into a vector of strings where ever there is an instance of delimiter (i.e. is delimiter is " " will give a list of words). Note that multiple delimiters in a row will give empty strings. Return by value.

     {
       // From http://stackoverflow.com/questions/236129/splitting-a-string-in-c
       Vector<std::string> elems;
       split_string(s, delim, elems);
       return elems;

◆ to_lower()

std::string oomph::StringConversion::to_lower ( const std::string & input )

Convert a string to lower case (outputs a copy).

     {
       std::string output(input);
       std::string::iterator it;
       for (it = output.begin(); it != output.end(); ++it)
       {
         ::tolower(*it);
       }
  
       return output;
     }

◆ to_string()

template<class T >

std::string oomph::StringConversion::to_string	(	T	object,
		unsigned	float_precision = `8`
	)

Conversion function that should work for anything with operator<< defined (at least all basic types).

     {
       std::stringstream ss;
       ss.precision(float_precision);
       ss << object;
       return ss.str();
     }

◆ to_upper()

std::string oomph::StringConversion::to_upper ( const std::string & input )

Convert a string to upper case (outputs a copy).

     {
       std::string output(input);
       std::string::iterator it;
       for (it = output.begin(); it != output.end(); ++it)
       {
         ::toupper(*it);
       }
       return output;
     }
