del	output parameter: always set to true by this function, meaning that the caller owns the QoreString pointer returned (and must delete it manually)
foff	ignored for this implementation of the file
xsink	ignored for this implementation of the file

Returns: a QoreString pointer, use the del output parameter to determine ownership of the pointer

static

returns a DateTimeNode value as generated from the ISO-8601 week information

NOTE: ISO-8601 week days go from 1 - 7 = Mon - Sun, a 0 return value means an exception was raised in the case the ISO-8601 week information is invalid

Parameters

year	the ISO-8601 year (may differ from the actual calendar year)
week	the ISO-8601 week number in the year
day	the ISO-8601 day number (1=Mon, 7=Sun)
xsink	if an error occurs, the Qore-language exception information will be added here

◆ getDateTimeRepresentation() [1/2]

virtual DLLEXPORT DateTime * DateTimeNode::getDateTimeRepresentation ( bool & del ) const

virtual

returns "this" as a DateTime, del is set to false

NOTE: Use the DateTimeValueHelper class instead of using this function directly

Parameters

del	output parameter: if del is true, then the returned DateTime pointer belongs to the caller (and must be deleted manually), if false, then it must not be

See also: DateTimeValueHelper

Reimplemented from AbstractQoreNode.

◆ getDateTimeRepresentation() [2/2]

virtual DLLEXPORT void DateTimeNode::getDateTimeRepresentation ( DateTime & dt ) const

virtual

assigns this date/time representation to the passed DateTime reference

Parameters

dt	the reference where the current date/time value will be copied

Reimplemented from AbstractQoreNode.

◆ getStringRepresentation() [1/2]

virtual DLLEXPORT QoreString * DateTimeNode::getStringRepresentation ( bool & del ) const

virtual

returns a string in the format YYYYMMDDHHmmSS, del is set to true

NOTE: do not use this function directly, use QoreStringValueHelper instead

Parameters

del	output parameter: if del is true, then the resulting QoreString pointer belongs to the caller (and must be deleted manually), if false it must not be

Returns: a QoreString pointer, use the del output parameter to determine ownership of the pointer

See also: QoreStringValueHelper

Reimplemented from AbstractQoreNode.

◆ getStringRepresentation() [2/2]

virtual DLLEXPORT void DateTimeNode::getStringRepresentation ( QoreString & str ) const

virtual

concatentates the date/time value in the format YYYYMMDDHHmmDD to an existing QoreString reference

Parameters

str	a reference to a QoreString where date/time value will be concatenated in the format YYYYMMDDHHmmDD

Reimplemented from AbstractQoreNode.

◆ is_equal_hard()

virtual DLLEXPORT bool DateTimeNode::is_equal_hard	(	const AbstractQoreNode *	v,
		ExceptionSink *	xsink
	)		const

virtual

tests for equality ("deep compare" including all contained values for container types) without type conversions (hard compare)

Parameters

v	the value to compare
xsink	if an error occurs, the Qore-language exception information will be added here

Returns: true if the objects are equal, false if not

Implements AbstractQoreNode.

◆ is_equal_soft()

virtual DLLEXPORT bool DateTimeNode::is_equal_soft	(	const AbstractQoreNode *	v,
		ExceptionSink *	xsink
	)		const

virtual

tests for equality with possible type conversion (soft compare)

this function does not throw any Qore-language exceptions

Parameters

v	the value to compare
xsink	is not used in this implementation of the function

Implements AbstractQoreNode.

◆ makeAbsolute() [1/2]

static DLLEXPORT DateTimeNode * DateTimeNode::makeAbsolute	(	const AbstractQoreZoneInfo *	n_zone,
		int	n_year,
		int	n_month,
		int	n_day,
		int	n_hour,
		int	n_minute,
		int	n_second,
		int	n_us,
		ExceptionSink *	xsink
	)

static

static "constructor" to create an absolute time, including microseconds, throws an exception with invalid date/time components
