OFDate::OFDate ( const OFDate & dateVal )

copy constructor

Parameters

dateVal date object to be copied

◆ OFDate() [3/3]

OFDate::OFDate	(	const unsigned int	year,
		const unsigned int	month,
		const unsigned int	day
	)

constructor with init values

Parameters

month	month value to be set
day	day value to be set

Member Function Documentation

◆ clear()

virtual void OFDate::clear ( )

virtual

reset the date value.

Sets the year, month and day to "0". NB: Date becomes invalid.

◆ getCurrentDate()

static OFDate OFDate::getCurrentDate ( )

static

get the current system date

Returns: date object with the current system date set

◆ getDay()

unsigned int OFDate::getDay ( ) const

get the currently stored day value

Returns: day value (might be invalid, i.e. out of range)

◆ getISOFormattedDate()

OFBool OFDate::getISOFormattedDate	(	OFString &	formattedDate,
		const OFBool	showDelimiter = `OFTrue`
	)		const

get the current date value in ISO format.

The two ISO date formats supported by this function are "YYYY-MM-DD" (with delimiters) and "YYYYMMDD" (without delimiters, useful for DICOM date type).

Parameters

formattedDate	reference to string variable where the result is stored
showDelimiter	flag, indicating whether to use delimiters ("-") or not

Returns: OFTrue if result variable has been set, OFFalse otherwise

◆ getMonth()

unsigned int OFDate::getMonth ( ) const

get the currently stored month value

Returns: month value (might be invalid, i.e. out of range)

◆ getYear()

unsigned int OFDate::getYear ( ) const

get the currently stored year value

Returns: year value (might be invalid, i.e. out of range)

◆ isDateValid()

static OFBool OFDate::isDateValid	(	const unsigned int	year,
		const unsigned int	month,
		const unsigned int	day
	)

staticprotected

check whether the given date is valid.

Currently, this method only checks whether the month is within the range of 1 to 12 and the day is within the range of 1 to 31. In the future this routine might be enhanced.

Parameters

year	year value to be checked
month	month value to be checked
day	day value to be checked

Returns: OFTrue if the current value is valid, OFFalse otherwise

◆ isValid()

virtual OFBool OFDate::isValid ( ) const

virtual

check whether the currently stored date value is valid.

Currently, this method only checks whether the month is within the range of 1 to 12 and the day is within the range of 1 to 31. In the future this routine might be enhanced.

Returns: OFTrue if the current value is valid, OFFalse otherwise

◆ operator!=()

virtual OFBool OFDate::operator!= ( const OFDate & dateVal ) const

virtual

comparison operator (unequal)

Parameters

dateVal date value compared with the current value

Returns: OFTrue if given date is unequal, OFFalse otherwise

◆ operator<()

virtual OFBool OFDate::operator< ( const OFDate & dateVal ) const

virtual

comparison operator (less than)

Parameters

dateVal date value compared with the current value

Returns: OFTrue if current date is earlier than the given value, OFFalse otherwise

◆ operator<=()

virtual OFBool OFDate::operator<= ( const OFDate & dateVal ) const

virtual

comparison operator (less than or equal)

Parameters

dateVal date value compared with the current value

Returns: OFTrue if current date is earlier than or identical to the given value, OFFalse otherwise

◆ operator=()

virtual OFDate& OFDate::operator= ( const OFDate & dateVal )

virtual

assignment operator

Parameters

dateVal date value to be set

Returns: reference to this object (with new value)

◆ operator==()

virtual OFBool OFDate::operator== ( const OFDate & dateVal ) const

virtual

comparison operator (equal)

Parameters

dateVal date value compared with the current value

Returns: OFTrue if given date is equal, OFFalse otherwise

◆ operator>()

virtual OFBool OFDate::operator> ( const OFDate & dateVal ) const

virtual

comparison operator (greater than)

Parameters

dateVal date value compared with the current value

Returns: OFTrue if current date is later than the given value, OFFalse otherwise

◆ operator>=()

virtual OFBool OFDate::operator>= ( const OFDate & dateVal ) const

virtual

comparison operator (greater than or equal)

Parameters

dateVal date value compared with the current value

Returns: OFTrue if current date is later than or identical to the given value, OFFalse otherwise

◆ setCurrentDate() [1/2]

OFBool OFDate::setCurrentDate ( )

set the date value to the current system date.

This function uses operating system dependent routines. If they are unavailable for some reason the current value is not modified.

Returns: OFTrue if the current system date has been set, OFFalse otherwise

◆ setCurrentDate() [2/2]

OFBool OFDate::setCurrentDate ( const time_t & tt )

protected

set the date value to the current system date.

This function uses operating system dependent routines. If they are unavailable for some reason the current value is not modified.

Parameters

tt	current system time (as returned by the time() function )

Returns: OFTrue if the current system date has been set, OFFalse otherwise

◆ setDate()

OFBool OFDate::setDate	(	const unsigned int	year,
		const unsigned int	month,
		const unsigned int	day
	)

set the date value to the specified date.

Before the new value is set it is checked using the "isValid()" routine.

Parameters

year	new year value to be set
month	new month value to be set
day	new day value to be set

Returns: OFTrue if the new value is valid and has been set, OFFalse otherwise

◆ setDay()

OFBool OFDate::setDay ( const unsigned int day )

set the date value to the specified day.

Before the new value is set it is checked using the "isValid()" routine.

Parameters

day	new day value to be set

Returns: OFTrue if the new value is valid and has been set, OFFalse otherwise

◆ setISOFormattedDate()

OFBool OFDate::setISOFormattedDate ( const OFString & formattedDate )

set the date value to the given ISO formatted date string.

The two ISO date formats supported by this function are "YYYY-MM-DD" (with arbitrary delimiters) and "YYYYMMDD" (without delimiters, useful for DICOM date type).

Parameters

formattedDate ISO formatted date value to be set

Returns: OFTrue if input is valid and result variable has been set, OFFalse otherwise

◆ setMonth()

OFBool OFDate::setMonth ( const unsigned int month )

set the date value to the specified month.

Before the new value is set it is checked using the "isValid()" routine.

Parameters

month new month value to be set

Returns: OFTrue if the new value is valid and has been set, OFFalse otherwise

◆ setYear()

OFBool OFDate::setYear ( const unsigned int year )

set the date value to the specified year.

Before the new value is set it is checked using the "isValid()" routine.

Parameters

year	new year value to be set

Returns: OFTrue if the new value is valid and has been set, OFFalse otherwise
