QDateTime QgsTimeDuration::addToDateTime

(

const QDateTime &

dateTime

)

Definition at line 363 of file qgstemporalutils.cpp.

isNull()

bool QgsTimeDuration::isNull ( ) const

inline

Returns true if the duration is null, i.e.

an empty duration.

operator==()

bool QgsTimeDuration::operator== ( const QgsTimeDuration &  other ) const

inline

Definition at line 69 of file qgstemporalutils.h.

toInterval()

QgsInterval QgsTimeDuration::toInterval

(

)

const

Converts the duration to an interval value.

Definition at line 278 of file qgstemporalutils.cpp.

toSeconds()

long long QgsTimeDuration::toSeconds

(

)

const

Returns the total duration in seconds.

Warning

If the duration contains year or month intervals then the returned value is approximate only, due to the variable length of these intervals.
