void Util::delete_string_array (  char **  sl  )

Deletes the array of strings returned by string_list_to_array. Parameters: sl  a null-terminated array of strings

bool Util::parseRGB (  Bitmap::BitmapColour &  rgb, const char *  s )

Parse an RGB specification. This is either a sequence of three integers separated by slashes (or in fact any non-number character), or else a string of the form #RRGGBB. Set the `rgb' structure to the resulting numbers. The integers must be in the range [0,255], and may be specified in decimal, octal, or hex. Parameters: rgb  the BitmapColour corresponding to the s argument s  the RGB specification Returns: true if the parse is successful.

char ** Util::string_list_to_array (  string_list &  l  )

Convert a string_list to a null-terminated array of character pointers. The resulting array can conveniently be deleted using delete_string_array. Parameters: l  a string_list Returns: a pointer to a null-terminated array of null-terminated character arrays

string_list & Util::tokenise_string (  string  str  )

Tokenise string at whitespace. Parameters: str  the string to be tokenised Returns: a list containing the whitespace-separated tokens in the string

void Util::verbosity (  const verbosities  level  )

Sets the verbosity of the methods in this class. Parameters: level  how verbose the class's methods should be
