Detailed Description

Implementation of data provider temporal properties for QgsVectorDataProviders.

Data provider temporal capabilities reflect the temporal capabilities of a QgsDataProvider. Unlike QgsMapLayerTemporalProperties, these settings are not user-configurable, and should only be set by the QgsDataProvider itself.

Since: QGIS 3.14

Constructor & Destructor Documentation

◆ QgsVectorDataProviderTemporalCapabilities()

QgsVectorDataProviderTemporalCapabilities::QgsVectorDataProviderTemporalCapabilities ( bool enabled = false )

Constructor for QgsVectorDataProviderTemporalCapabilities.

The enabled argument specifies whether the data provider has temporal capabilities.

Definition at line 20 of file qgsvectordataprovidertemporalcapabilities.cpp.

Member Function Documentation

◆ availableTemporalRange()

const QgsDateTimeRange & QgsVectorDataProviderTemporalCapabilities::availableTemporalRange ( ) const

Returns the datetime range extent from which temporal data is available from the provider.

See also: setAvailableTemporalRange()

Definition at line 43 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ endField()

QString QgsVectorDataProviderTemporalCapabilities::endField ( ) const

Returns the name of the end datetime field, which stores the end time for the feature's time spans.

See also: setEndField(); startField()

Definition at line 58 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ mode()

Qgis::VectorDataProviderTemporalMode QgsVectorDataProviderTemporalCapabilities::mode ( ) const

Returns the temporal properties mode.

See also: setMode()

Definition at line 25 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ setAvailableTemporalRange()

void QgsVectorDataProviderTemporalCapabilities::setAvailableTemporalRange ( const QgsDateTimeRange & range )

Sets the datetime range extent from which temporal data is available from the provider.

See also: availableTemporalRange()

Definition at line 35 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ setEndField()

void QgsVectorDataProviderTemporalCapabilities::setEndField ( const QString & field )

Sets the name of the end datetime field, which stores the end time for the feature's time spans.

See also: endField(); setStartField()

Definition at line 63 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ setMode()

void QgsVectorDataProviderTemporalCapabilities::setMode ( Qgis::VectorDataProviderTemporalMode mode )

Sets the temporal properties mode.

See also: mode()

Definition at line 30 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ setStartField()

void QgsVectorDataProviderTemporalCapabilities::setStartField ( const QString & field )

Sets the name of the start datetime field, which stores the start time for the feature's time spans.

If mode() is ModeFeatureDateTimeInstantFromField, then this field stores both the start AND end times.

See also: startField(); setEndField()

Definition at line 53 of file qgsvectordataprovidertemporalcapabilities.cpp.

◆ startField()

QString QgsVectorDataProviderTemporalCapabilities::startField ( ) const

Returns the name of the start datetime field, which contains the start time for the feature's time spans.

If mode() is ProviderStoresFeatureDateTimeInstantInField, then this field stores both the start AND end times.

See also: setStartField(); endField()
