class ParseString : public string

Subclass of string with added functionaity for parsing

Inheritance:

Public Methods

void lower(void)

Converts the entire string to lower case letters

ParseString(char *value)

Constructor taking a character array to initialize the string

ParseString(void)

Constructor taking no arguments

void tidy(void)

Removes preceeding and excess spaces

string token(int n, char delim=' ')

Returns the given token in the string using the delimiter

ParseString(char *value)

Constructor taking a character array to initialize the string. The routine simply calls the base class string constructor function which takes a character array as an argument.

ParseString(void)

Constructor taking no arguments. The routine simply calls the base class string constructor function which requires no arguments.

void tidy(void)

Removes preceeding and excess spaces. The routine loops over the string removing any spaces in front of the text. It then reduces spacing in the string to single space characters. For example the string " hello there" would become "hello there" after a call to tidy.

void lower(void)

Converts the entire string to lower case letters. Loops over the string elements and if they are capital letters it converts them to the lower case equivalent.

string token(int n, char delim=' ')

Returns the given token in the string using the delimiter. The routine loops over the string elements looking for the delimiter character. When it is found it will mark the beginning of the token and continue looping until it finds the next delimiter or end of the string which marks the end of the token. It then uses the substr method inherited from string to return the token substring. Token zero starts at the begining of the string and ends at the first delimiter or end of the string.

Parameters:

n - number of token requested
delim - delimiter character used to divide the string
