char * mrpt::system::strtok ( char *  str,
const char *  strDelimit,
char **  context 
)

An OS-independent method for tokenizing a string.

The extra parameter "context" must be a pointer to a "char*" variable, which needs no initialization and is used to save information between calls to strtok.

void mrpt::system::tokenize ( const std::string inString,
const std::string inDelimiters,
std::deque< std::string > &  outTokens,
bool  skipBlankTokens = true 
)

Tokenizes a string according to a set of delimiting characters.

Example:

std::vector<std::string> tokens;
tokenize(" - Pepe-Er Muo"," -",tokens);

Will generate 3 tokens:

  • "Pepe"
  • "Er"
  • "Muo"
    Parameters
    [in]skipBlankTokensIf true, consecutive "delimiters" will be considered one single delimiters. If false, a blank token will be returned between each pair of delimiters.
