Functions

int cmp_nocase (const string &s, const string &s2)

int toupper_uh (int ch)

int cmp_nocase_uh (const string &s, const string &s2)

string downcase (const string &s)

Returns the input string with all uppercase letters converted to lowercase.

string upcase (const string &s)

Returns the input string with all lowercase letters converted to uppercase.

int extract_words (const string &str, vector_string &words)

Divides the string into a number of words according to whitespace.

void tokenize (const string &str, vector_string &words, const string &delimiters)

Chops the source string up into pieces delimited by any of the characters specified in delimiters.

string trim_left (const string &str)

Returns a new string representing the contents of the given string with the leading whitespace removed.

string trim_right (const string &str)

Returns a new string representing the contents of the given string with the trailing whitespace removed.

int string_to_int (const string &str, string &tail)

A string-interface wrapper around the C library strtol().

bool string_to_int (const string &str, int &result)

Another flavor of string_to_int(), this one returns true if the string is a perfectly valid integer (and sets result to that value), or false otherwise.

double string_to_double (const string &str, string &tail)

A string-interface wrapper around the C library strtol().

bool string_to_double (const string &str, double &result)

Another flavor of string_to_double(), this one returns true if the string is a perfectly valid number (and sets result to that value), or false otherwise.

bool string_to_float (const string &str, float &result)

Another flavor of string_to_float(), this one returns true if the string is a perfectly valid number (and sets result to that value), or false otherwise.

string downcase ( const string & s )

Returns the input string with all uppercase letters converted to lowercase.

int extract_words ( const string & str,

vector_string & words

)

Divides the string into a number of words according to whitespace.
The words vector should be cleared by the user before calling; otherwise, the list of words in the string will be appended to the end of whatever was there before.
The return value is the number of words extracted.

bool string_to_double ( const string & str,

double & result

)

Another flavor of string_to_double(), this one returns true if the string is a perfectly valid number (and sets result to that value), or false otherwise.

Referenced by string_to_int().

double string_to_double ( const string & str,

string & tail

)

A string-interface wrapper around the C library strtol().
This parses the ASCII representation of an floating-point number, and then sets tail to everything that follows the first valid integer read. If, on exit, str == tail, there was no valid integer in the source string; if !tail.empty(), there was garbage after the number.
It is legal if str and tail refer to the same string.
Definition at line 305 of file string_utils.cxx.

bool string_to_float ( const string & str,

float & result

)

Another flavor of string_to_float(), this one returns true if the string is a perfectly valid number (and sets result to that value), or false otherwise.

Definition at line 347 of file string_utils.cxx.

bool string_to_int ( const string & str,

int & result

)

Another flavor of string_to_int(), this one returns true if the string is a perfectly valid integer (and sets result to that value), or false otherwise.

void tokenize ( const string & str,

vector_string & words,

const string & delimiters

)

Chops the source string up into pieces delimited by any of the characters specified in delimiters.
Repeated delimiter characters represent zero-length tokens.
It is the user's responsibility to ensure the output vector is cleared before calling this function; the results will simply be appended to the end of the vector.
