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

Since: Qore 0.8.12.4

◆ makeAbsolute() [2/2]

static DLLEXPORT DateTimeNode* DateTimeNode::makeAbsolute	(	const AbstractQoreZoneInfo *	zone,
		int64	seconds,
		int	us = `0`
	)

static

static "constructor" to create an absolute time as an offset from the epoch, including microseconds

Parameters

zone	time zone for the date/time value, 0 = UTC,

See also: currentTZ()

Parameters

seconds	the number of seconds from January 1, 1970
us	the microseconds portion of the time

◆ makeAbsoluteLocal()

static DLLEXPORT DateTimeNode* DateTimeNode::makeAbsoluteLocal	(	const AbstractQoreZoneInfo *	zone,
		int64	seconds,
		int	us = `0`
	)

static

static "constructor" to create an absolute time as an offset from the given time zone's epoch, including microseconds

Parameters

zone	time zone for the date/time value, 0 = UTC,

See also: currentTZ()

Parameters

seconds	the number of seconds from January 1, 1970 in the time zone passed as the first argument
us	the microseconds portion of the time

◆ realCopy()

virtual DLLEXPORT AbstractQoreNode* DateTimeNode::realCopy ( ) const

virtual

returns a copy of the object; the caller owns the reference count

Returns: a copy of the object; the caller owns the reference count

Implements AbstractQoreNode.

◆ subtractBy() [1/2]

DLLEXPORT DateTimeNode* DateTimeNode::subtractBy ( const DateTime & dt ) const

subtracts a DateTime value from the current value and returns the new value, the caller owns the pointer's reference count

Returns: a new DateTimeNode value, the caller owns the pointer's reference count

◆ subtractBy() [2/2]

DLLEXPORT DateTimeNode* DateTimeNode::subtractBy ( const DateTime * dt ) const

subtracts a DateTime value from the current value and returns the new value, the caller owns the pointer's reference count

Returns: a new DateTimeNode value, the caller owns the pointer's reference count
