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 void setDefaultsFromDataProviderTemporalCapabilities(const QgsDataProviderTemporalCapabilities *capabilities)=0
Sets the layers temporal settings to appropriate defaults based on a provider's temporal capabilities...
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:70
The class is used as a container of context for various read/write operations on other objects.
Base class for temporal property.
