Detailed Description

Implementation of data provider temporal properties for QgsRasterDataProviders.

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

Member Enumeration Documentation

◆ IntervalHandlingMethod

Method to use when resolving a temporal range to a data provider layer or band.

Enumerator
MatchUsingWholeRange 

Use an exact match to the whole temporal range.

MatchExactUsingStartOfRange 

Match the start of the temporal range to a corresponding layer or band, and only use exact matching results.

MatchExactUsingEndOfRange 

Match the end of the temporal range to a corresponding layer or band, and only use exact matching results.

FindClosestMatchToStartOfRange 
FindClosestMatchToEndOfRange 

Match the start of the temporal range to the least previous closest datetime.

Match the end of the temporal range to the least previous closest datetime.

Definition at line 51 of file qgsrasterdataprovidertemporalcapabilities.h.

Constructor & Destructor Documentation

◆ QgsRasterDataProviderTemporalCapabilities()

QgsRasterDataProviderTemporalCapabilities::QgsRasterDataProviderTemporalCapabilities ( bool  enabled = false)

Constructor for QgsRasterDataProviderTemporalProperties.

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

Definition at line 20 of file qgsrasterdataprovidertemporalcapabilities.cpp.

Member Function Documentation

◆ availableReferenceTemporalRange()

const QgsDateTimeRange & QgsRasterDataProviderTemporalCapabilities::availableReferenceTemporalRange ( ) const

Returns the available reference datetime range, which indicates the maximum extent of datetime values available for reference temporal ranges from the provider.

See also
setAvailableReferenceTemporalRange()

Definition at line 46 of file qgsrasterdataprovidertemporalcapabilities.cpp.

◆ availableTemporalRange()

const QgsDateTimeRange & QgsRasterDataProviderTemporalCapabilities::availableTemporalRange ( ) const

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

See also
setAvailableTemporalRange()

Definition at line 33 of file qgsrasterdataprovidertemporalcapabilities.cpp.

◆ intervalHandlingMethod()

QgsRasterDataProviderTemporalCapabilities::IntervalHandlingMethod QgsRasterDataProviderTemporalCapabilities::intervalHandlingMethod ( ) const

Returns the desired method to use when resolving a temporal interval to matching layers or bands in the data provider.

See also
setIntervalHandlingMethod()

Definition at line 61 of file qgsrasterdataprovidertemporalcapabilities.cpp.

◆ requestedTemporalRange()

const QgsDateTimeRange & QgsRasterDataProviderTemporalCapabilities::requestedTemporalRange ( ) const

Returns the requested temporal range.

Intended to be used by the provider in fetching data.

Definition at line 56 of file qgsrasterdataprovidertemporalcapabilities.cpp.

◆ setAvailableReferenceTemporalRange()

void QgsRasterDataProviderTemporalCapabilities::setAvailableReferenceTemporalRange ( const QgsDateTimeRange &  range)

Sets the available reference datetime range.

This is to be used for bi-temporal based data. Where data can have both nominal and reference times.

See also
availableReferenceTemporalRange()

Definition at line 38 of file qgsrasterdataprovidertemporalcapabilities.cpp.

◆ setAvailableTemporalRange()

void QgsRasterDataProviderTemporalCapabilities::setAvailableTemporalRange ( const QgsDateTimeRange &  range)

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

See also
availableTemporalRange()

Definition at line 25 of file qgsrasterdataprovidertemporalcapabilities.cpp.

◆ setIntervalHandlingMethod()

void QgsRasterDataProviderTemporalCapabilities::setIntervalHandlingMethod ( IntervalHandlingMethod  method)

Sets the desired method to use when resolving a temporal interval to matching layers or bands in the data provider.

See also
intervalHandlingMethod()

Definition at line 66 of file qgsrasterdataprovidertemporalcapabilities.cpp.
