Detailed Description

This class implements a simply-constrained value-semantic type representing the composition of date and time values. Valid date values for the "date" part of a Datetime object are the same as those defined for Date objects; similarly, valid time values for the "time" part of a Datetime object are similar to those defined for Time objects (but with additional precision). Relational operators are disallowed on Datetime objects whose "time" part has the same value as that of a default constructed Time object.

Write the value of this object to the specified output stream in a human-readable format, and return a reference to stream. Optionally specify an initial indentation level, whose absolute value is incremented recursively for nested objects. If level is specified, optionally specify spacesPerLevel, whose absolute value indicates the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level). If stream is not valid on entry, this operation has no effect. Note that this human-readable format is not fully specified, and can change without notice.

◆ printToBuffer()

int bdlt::Datetime::printToBuffer	(	char *	result,
		int	numBytes,
		int	fractionalSecondPrecision = `6`
	)		const

Efficiently write to the specified result buffer no more than the specified numBytes of a representation of the value of this object. Optionally specify fractionalSecondPrecision digits to indicate how many fractional second digits to output. If fractionalSecondPrecision is not specified then 6 fractional second digits will be output (3 digits for milliseconds and 3 digits for microseconds). Return the number of characters (not including the null character) that would have been written if the limit due to numBytes were not imposed. result is null-terminated unless numBytes is 0. The behavior is undefined unless 0 <= numBytes, 0 <= fractionalSecondPrecision <= 6, and result refers to at least numBytes contiguous bytes. Note that the return value is greater than or equal to numBytes if the output representation was truncated to avoid result overrun.

◆ setYearDay()

void bdlt::Datetime::setYearDay	(	int	year,
		int	dayOfYear
	)

inline

Set the "date" part of this object to have the value represented by the specified year and dayOfYear attribute values. The behavior is undefined unless year and dayOfYear represent a valid Date value (i.e., true == Date::isValidYearDay(year, dayOfYear)). Note that this method has no effect on the "time" part of this object.

◆ setYearDayIfValid()

int bdlt::Datetime::setYearDayIfValid	(	int	year,
		int	dayOfYear
	)

inline

Set this object to have the value represented by the specified year and dayOfYear if they comprise a valid Date value (see Date::isValidYearDay). Return 0 on success, and a non-zero value (with no effect) otherwise.

◆ setYearMonthDay()

void bdlt::Datetime::setYearMonthDay	(	int	year,
		int	month,
		int	day
	)

inline

Set the "date" part of this object to have the value represented by the specified year, month, and day attribute values. The behavior is undefined unless year, month, and day represent a valid Date value (i.e., true == Date::isValidYearMonthDay(year, month, day)). Note that this method has no effect on the "time" part of this object.

◆ setYearMonthDayIfValid()

int bdlt::Datetime::setYearMonthDayIfValid	(	int	year,
		int	month,
		int	day
	)

inline

Set this object to have the value represented by the specified year, month, and day if they comprise a valid Date value (see Date::isValidYearMonthDay). Return 0 on success, and a non-zero value (with no effect) otherwise.

◆ streamOut()

bsl::ostream & bdlt::Datetime::streamOut ( bsl::ostream & stream ) const

inline

Deprecated:: Use print instead.

Format this datetime to the specified output stream and return a reference to the modifiable stream.

◆ time()

Time bdlt::Datetime::time ( ) const

inline

◆ validateAndSetDatetime()

int bdlt::Datetime::validateAndSetDatetime	(	int	year,
		int	month,
		int	day,
		int	hour = `0`,
		int	minute = `0`,
		int	second = `0`,
		int	millisecond = `0`
	)

inline

Deprecated:: Use setDatetimeIfValid instead.

Set the "date" part of this object's value to the specified year, month, and day, and the "time" part to the optionally specified hour, minute, second, and millisecond, if they represent a valid Datetime value, with trailing fields that are not specified set to 0. Return 0 on success, and a non-zero value (with no effect) otherwise.

◆ hashAppend

template<class HASHALG >

void hashAppend	(	HASHALG &	hashAlg,
		const Datetime &
	)

friend

Pass the specified object to the specified hashAlg. This function integrates with the bslh modular hashing system and effectively provides a bsl::hash specialization for Datetime.

◆ operator!=

bool operator!=	(	const Datetime &	,
		const Datetime &
	)

friend

Return true if the specified lhs and rhs Datetime objects do not have the same value, and false otherwise. Two Datetime objects do not have the same value if they do not have the same values for either of their "date" or "time" parts, respectively.

◆ operator-

DatetimeInterval operator-	(	const Datetime &	,
		const Datetime &
	)

friend

Return a DatetimeInterval object having a value that is the difference between the specified lhs (Datetime) and the specified rhs (Datetime). If the hour attribute of either operand is 24, the result is the same as if that hour attribute is 0. The behavior is undefined unless the resulting value is in the valid range for a DatetimeInterval object.

◆ operator<

bool operator<	(	const Datetime &	,
		const Datetime &
	)

friend

Return true if the value of the specified lhs object is less than the value of the specified rhs object, and false otherwise. A Datetime object a is less than a Datetime object b if a.date() < b.date(), or if a.date() == b.date() and the time portion of a is less than the time portion of b. The behavior is undefined unless 24 != lhs.hour() && 24 != rhs.hour().

◆ operator<=

bool operator<=	(	const Datetime &	,
		const Datetime &
	)

friend

Return true if the value of the specified lhs object is less than or equal to the value of the specified rhs object, and false otherwise. The behavior is undefined unless 24 != lhs.hour() && 24 != rhs.hour().

◆ operator==

bool operator==	(	const Datetime &	,
		const Datetime &
	)

friend

Return true if the specified lhs and rhs objects have the same value, and false otherwise. Two Datetime objects have the same value if they have the same values for their "date" and "time" parts, respectively.

◆ operator>

bool operator>	(	const Datetime &	,
		const Datetime &
	)

friend

Return true if the value of the specified lhs object is greater than the value of the specified rhs object, and false otherwise. A Datetime object a is greater than a Datetime object b if a.date() > b.date(), or if a.date() == b.date() and the time portion of a is greater than the time portion of b. The behavior is undefined unless 24 != lhs.hour() && 24 != rhs.hour().

◆ operator>=

bool operator>=	(	const Datetime &	,
		const Datetime &
	)

friend

Return true if the value of the specified lhs object is greater than or equal to the value of the specified rhs object, and false otherwise. The behavior is undefined unless 24 != lhs.hour() && 24 != rhs.hour().
