TIME	One date & time value.
DURATION	A duration not associated with any start or end.
START_END	A start and an end.
START_DURATION	A start and a duration.
DURATION_END	A duration and an end.
RECURRING	Additional flag: recurring time interval.
ANY_INTERVAL	A bit mask of all time-interval formats (non-recurring).
ANY	A bit mask of all possible formats.

[in]	recurrences	If non-zero, the time-interval is recurring, with that number of recurrences.

Member Function Documentation

◆ clear()

void ts::ISOTime::clear ( )

Reset the content of the object to an invalid state.

◆ isValid()

bool ts::ISOTime::isValid ( ) const

inline

Check if this object contains a valid value.

Returns: True if this object contains a valid value, false otherwise.

◆ isSingleTime()

bool ts::ISOTime::isSingleTime ( ) const

inline

Check if this object contains a single date & time value.

Returns: True if this object contains a single date & time value, false otherwise.

◆ isInterval()

bool ts::ISOTime::isInterval ( ) const

inline

Check if this object contains a time interval (recurring or not).

Returns: True if this object contains a time interval, false otherwise.

◆ isRecurring()

bool ts::ISOTime::isRecurring ( ) const

inline

Check if this object contains a recurring interval.

Returns: True if this object contains a recurring interval, false otherwise.

◆ isUnbounded()

bool ts::ISOTime::isUnbounded ( ) const

inline

Check if this object contains an unbounded recurring interval.

Returns: True if this object contains an unbounded recurring interval, false otherwise.

◆ type()

TimeType ts::ISOTime::type ( ) const

inline

Get the type of ISO 8601 time data.

Returns: The type of ISO 8601 time data.

◆ toString()

UString ts::ISOTime::toString ( TimeType format = NONE ) const

Format this object as a ISO 8601 string.

Parameters

[in] format Required format. In NONE, use the default format for that object.

Returns: The corresponding ISO 8601 string.

◆ fromString()

bool ts::ISOTime::fromString ( const UString & str )

Set the value of this object from a string in ISO 8601 format.

Parameters

[in] str A string in ISO 8601 format.

Returns: True on success, false on error (the object is then invalid).

◆ operator Time()

ts::ISOTime::operator Time ( ) const

inline

Conversion to a Time value.

Returns: The single date and time or the start date for a time interval. Return ts::Time::Epoch on error.

◆ start()

Time ts::ISOTime::start ( ) const

Get the time interval start time.

Returns: The start date for a time interval or single date and time. Return ts::Time::Epoch on error.

◆ end()

Time ts::ISOTime::end ( ) const

Get the time interval end time.

Returns: The end date for a time interval or single date and time. Return ts::Time::Epoch on error.

◆ duration()

cn::milliseconds ts::ISOTime::duration ( ) const

Get the duration of the time interval.

Returns: The duration of the time interval, zero otherwise.

◆ recurrences()

size_t ts::ISOTime::recurrences ( ) const

inline

Returns: The number of recurrences of the time interval for a recurring interval, zero otherwise.

◆ TimeFromISO()

Time ts::ISOTime::TimeFromISO ( const UString & str )

static

Decode a time from an ISO 8601 representation. Missing date fields default to the current UTC time. Missing time fields default to zero. The mpeg7:timePointType format is an extension of ISO 8601 and is also recognized here.

Parameters

[in] str A string describing a date and time in ISO 8601 representation.

Returns: The converted time or ts::Time::Epoch if the string cannot be decoded.

◆ DurationFromISO()

static

Decode a duration from an ISO 8601 representation.

Parameters

[in] str A string describing a duration in ISO 8601 representation.

Returns: The converted duration in milliseconds or a negative value if the string cannot be decoded.

◆ ToISO() [1/3]

UString ts::ISOTime::ToISO ( const Time & time )

inlinestatic

◆ ToISO() [2/3]

template<class Rep, class Period>

UString ts::ISOTime::ToISO	(	const Time &	time,
		cn::duration< Rep, Period >	utc_offset )

template<class Rep, class Period>

UString ts::ISOTime::ToISO ( cn::duration< Rep, Period > duration )

inlinestatic

Format a duration in ISO 8601 representation.

Parameters

[in] duration Time interval duration.

Returns: A string describing the duration in ISO 8601 representation.
