Abstract base class for processing algorithms.
virtual QString group() const
Returns the name of the group this algorithm belongs to.
virtual QString groupId() const
Returns the unique ID of the group this algorithm belongs to.
virtual QString shortHelpString() const
Returns a localised short helper string for the algorithm.
virtual QVariantMap processAlgorithm(const QVariantMap &parameters, QgsProcessingContext &context, QgsProcessingFeedback *feedback) SIP_THROW(QgsProcessingException)=0
Runs the algorithm using the specified parameters.
Contains information about the context in which a processing algorithm is executed.
Base class for providing feedback from a processing algorithm.
Takes care of writing vector tiles.
