Member Enumeration Documentation

◆ MatchingTemporalDatasetMethod

enum QgsMeshDataProviderTemporalCapabilities::MatchingTemporalDatasetMethod

Method for selection of temporal mesh dataset from a range time.

Enumerator

FindClosestDatasetBeforeStartRangeTime

FindClosestDatasetFromStartRangeTime

Finds the closest dataset which have its time before the requested start range time.

Finds the closest dataset before or after the requested start range time

Definition at line 41 of file qgsmeshdataprovidertemporalcapabilities.h.

Constructor & Destructor Documentation

◆ QgsMeshDataProviderTemporalCapabilities()

QgsMeshDataProviderTemporalCapabilities::QgsMeshDataProviderTemporalCapabilities ( )

Constructor for QgsMeshDataProviderTemporalCapabilities.

Definition at line 22 of file qgsmeshdataprovidertemporalcapabilities.cpp.

Member Function Documentation

◆ addDatasetTime()

void QgsMeshDataProviderTemporalCapabilities::addDatasetTime	(	int	group,
		double	time )

Adds a time (in provider unit) from a dataset contained in group.

Note: must be used only by the mesh data provider, all dataset need to be added one after one

Definition at line 92 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ addDatasetTimeInMilliseconds()

void QgsMeshDataProviderTemporalCapabilities::addDatasetTimeInMilliseconds	(	int	group,
		qint64	time )

Adds a time (in milliseconds) from a dataset contained in group.

Note: must be used only by the mesh data provider, all dataset need to be added one after one

Definition at line 86 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ addGroupReferenceDateTime()

void QgsMeshDataProviderTemporalCapabilities::addGroupReferenceDateTime	(	int	group,
		const QDateTime &	reference )

Adds a reference date/time from a dataset group.

Note: must be used only by the mesh data provider

Definition at line 78 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ clear()

void QgsMeshDataProviderTemporalCapabilities::clear ( )

Clears all stored reference times and dataset times.

Definition at line 167 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ datasetIndexClosestBeforeRelativeTime()

QgsMeshDatasetIndex QgsMeshDataProviderTemporalCapabilities::datasetIndexClosestBeforeRelativeTime	(	int	group,
		qint64	timeSinceGlobalReference ) const

Returns the last dataset with time less than or equal to timeSinceGlobalReference.

Returns invalid dataset index if timeSinceGlobalReference is outside the time extent of the dataset group

Note: for non temporal dataset group, timeSinceGlobalReference is not used and the unique dataset is returned

Definition at line 55 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ datasetIndexClosestFromRelativeTime()

QgsMeshDatasetIndex QgsMeshDataProviderTemporalCapabilities::datasetIndexClosestFromRelativeTime	(	int	group,
		qint64	timeSinceGlobalReference ) const

Returns the closest dataset index from the timeSinceGlobalReference.

Returns invalid dataset index if timeSinceGlobalReference is outside the time extent of the dataset group

Note: for non temporal dataset group, timeSinceGlobalReference is not used and the unique dataset is returned

Definition at line 26 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ datasetTime()

qint64 QgsMeshDataProviderTemporalCapabilities::datasetTime ( const QgsMeshDatasetIndex & index ) const

Returns the relative time in milliseconds of the dataset.

Definition at line 155 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ firstTimeStepDuration()

qint64 QgsMeshDataProviderTemporalCapabilities::firstTimeStepDuration ( int group ) const

Returns the duration of the first time step of the dataset group with index group.

The value is -1 if the dataset group is not present or if it contains only one dataset (non temporal dataset)

Definition at line 174 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ hasReferenceTime()

bool QgsMeshDataProviderTemporalCapabilities::hasReferenceTime ( ) const

Returns whether the reference time is set.

Definition at line 98 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ referenceTime()

QDateTime QgsMeshDataProviderTemporalCapabilities::referenceTime ( ) const

Returns the reference time.

Definition at line 103 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ setTemporalUnit()

void QgsMeshDataProviderTemporalCapabilities::setTemporalUnit ( Qgis::TemporalUnit temporalUnit )

Sets the temporal unit (temporalUnit) used to read data by the data provider.

Temporal units supported are milliseconds, seconds, minutes, hors, days and weeks

Definition at line 145 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ temporalUnit()

Qgis::TemporalUnit QgsMeshDataProviderTemporalCapabilities::temporalUnit ( ) const

Returns the temporal unit used to read data by the data provider.

Definition at line 150 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ timeExtent() [1/2]

QgsDateTimeRange QgsMeshDataProviderTemporalCapabilities::timeExtent ( ) const

Returns the time extent using the internal reference time and the first and last times available from the all the dataset.

Definition at line 108 of file qgsmeshdataprovidertemporalcapabilities.cpp.

◆ timeExtent() [2/2]

QgsDateTimeRange QgsMeshDataProviderTemporalCapabilities::timeExtent ( const QDateTime & reference ) const

Returns the time extent using an external reference date time and the first and last times available from the all the dataset.

Definition at line 113 of file qgsmeshdataprovidertemporalcapabilities.cpp.
