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 93 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 87 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 alls stored reference times and dataset times.
Definition at line 170 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 54 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 24 of file qgsmeshdataprovidertemporalcapabilities.cpp.
◆ datasetTime()
| qint64 QgsMeshDataProviderTemporalCapabilities::datasetTime | ( | const QgsMeshDatasetIndex & | index | ) | const |
Returns the relative time in milliseconds of the dataset.
Definition at line 158 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 177 of file qgsmeshdataprovidertemporalcapabilities.cpp.
◆ hasReferenceTime()
| bool QgsMeshDataProviderTemporalCapabilities::hasReferenceTime | ( | ) | const |
Returns whether the reference time is set.
Definition at line 99 of file qgsmeshdataprovidertemporalcapabilities.cpp.
◆ referenceTime()
| QDateTime QgsMeshDataProviderTemporalCapabilities::referenceTime | ( | ) | const |
Returns the reference time.
Definition at line 104 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 148 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 153 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 109 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.
