template<class InputT , class OutputT >

std::basic_string<OutputT> boost::date_time::convert_string_type ( const std::basic_string< InputT > & inp_str )

inline

Converts a string from one value_type to another.

Converts a wstring to a string (or a string to wstring). If both template parameters are of same type, a copy of the input string is returned.

std::string boost::date_time::convert_to_lower ( std::string inp )

inline

A function to replace the std::transform( , , ,tolower) construct.

This function simply takes a string, and changes all the characters in that string to lowercase (according to the default system locale). In the event that a compiler does not support locales, the old C style tolower() is used.

Calculates the number of days since the previous weekday.

Calculates the number of days since the previous weekday If the date given falls on a Sunday and the given weekday is Tuesday the result will be 5 days. The answer will be a positive number because Tuesday is 5 days before Sunday, not -5 days before.

	)

Find index of a string in either of 2 arrays.

find_match searches both arrays for a match to 's'. Both arrays must contain 'size' elements. The index of the match is returned. If no match is found, 'size' is returned. Ex. "Jan" returns 0, "Dec" returns 11, "Tue" returns 2. 'size' can be sent in with: (greg_month::max)() (which 12), (greg_weekday::max)() + 1 (which is 7) or date_time::NumSpecialValues

Expected output is either a numeric representation or a special values representation.

Ex. "12", "+infinity", "not-a-number", etc.

template<class date_type >

date_type boost::date_time::parse_date	(	const std::string &	s,
		int	order_spec = `ymd_order_iso`
	)

Generic function to parse a delimited date (eg: 2002-02-10)

Accepted formats are: "2003-02-10" or " 2003-Feb-10" or "2003-Feburary-10" The order in which the Month, Day, & Year appear in the argument string can be accomodated by passing in the appropriate ymd_order_spec

template<class time_duration >

time_duration boost::date_time::parse_delimited_time_duration ( const std::string & s )

inline

Creates a time_duration object from a delimited string.

Expected format for string is "[-]h[h][:mm][:ss][.fff]". If the number of fractional digits provided is greater than the precision of the time duration type then the extra digits are truncated.

A negative duration will be created if the first character in string is a '-', all other '-' will be treated as delimiters. Accepted delimiters are "-:,.".

template<class time_type >

time_type boost::date_time::parse_iso_time	(	const std::string &	s,

Parse time string of form YYYYMMDDThhmmss where T is delimeter between date and time.

inline

Generates a date object representing the date of the previous weekday from the given date.

Generates a date object representing the date of the previous weekday from the given date. If the date given is 2004-May-9 (a Sunday) and the given weekday is Tuesday then the resulting date will be 2004-May-4.

		unsigned int	max_length
	)

inline

Helper function for parsing varied length strings into integers.

Will consume 'max_length' characters from stream only if those characters are digits. Returns '-1' if no number can be parsed. Will not parse a number preceeded by a '+' or '-'.
