Class: QgsVectorDataProviderTemporalCapabilities

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.

Added in version 3.14.

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

Parameters:

enabled (bool = False)

__init__(a0: QgsVectorDataProviderTemporalCapabilities)

Parameters:

a0 (QgsVectorDataProviderTemporalCapabilities)

TemporalMode

alias of VectorDataProviderTemporalMode

availableTemporalRange(self) → QgsDateTimeRange

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

setAvailableTemporalRange()

Return type:

QgsDateTimeRange

endField(self) → str

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

startField()

Return type:

str

mode(self) → Qgis.VectorDataProviderTemporalMode

Returns the temporal properties mode.

setMode()

Return type:

Qgis.VectorDataProviderTemporalMode

setAvailableTemporalRange(self, range: QgsDateTimeRange)

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

Parameters:

range (QgsDateTimeRange)

setEndField(self, field: str | None)

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

Parameters:

field (Optional[str])

setMode(self, mode: Qgis.VectorDataProviderTemporalMode)

Sets the temporal properties mode.

mode()

Parameters:

mode (Qgis.VectorDataProviderTemporalMode)

setStartField(self, field: str | None)

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.

setEndField()

Parameters:

field (Optional[str])

startField(self) → str

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