TemporalIntervalMatchMethod
Method to use when resolving a temporal range to a data provider layer or band.
Definition: qgis.h:865
@ MatchUsingWholeRange
Use an exact match to the whole temporal range.
RasterTemporalMode
Raster layer temporal modes.
Definition: qgis.h:852
Base class for handling properties relating to a data provider's temporal capabilities.
Base class for storage of map layer temporal properties.
virtual QDomElement writeXml(QDomElement &element, QDomDocument &doc, const QgsReadWriteContext &context)=0
Writes the properties to a DOM element, to be used later with readXml().
virtual QgsDateTimeRange calculateTemporalExtent(QgsMapLayer *layer) const
Attempts to calculate the overall temporal extent for the specified layer, using the settings defined...
virtual void setDefaultsFromDataProviderTemporalCapabilities(const QgsDataProviderTemporalCapabilities *capabilities)=0
Sets the layers temporal settings to appropriate defaults based on a provider's temporal capabilities...
virtual QList< QgsDateTimeRange > allTemporalRanges(QgsMapLayer *layer) const
Attempts to calculate the overall list of all temporal extents which are contained in the specified l...
virtual bool isVisibleInTemporalRange(const QgsDateTimeRange &range) const
Returns true if the layer should be visible and rendered for the specified time range.
virtual bool readXml(const QDomElement &element, const QgsReadWriteContext &context)=0
Reads temporal properties from a DOM element previously written by writeXml().
Base class for all map layer types.
Definition: qgsmaplayer.h:72
Implementation of map layer temporal properties for raster layers.
The class is used as a container of context for various read/write operations on other objects.
virtual QgsTemporalProperty::Flags flags() const
Returns flags associated to the temporal property.
