virtual QString group() const
Returns the name of the group this algorithm belongs to.
virtual bool prepareAlgorithm(const QVariantMap &parameters, QgsProcessingContext &context, QgsProcessingFeedback *feedback)
Prepares the algorithm to run using the specified parameters.
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 QString shortDescription() const
Returns an optional translated short description of the algorithm.
virtual QString displayName() const =0
Returns the translated algorithm name, which should be used for any user-visible display of the algor...
virtual QVariantMap processAlgorithm(const QVariantMap &parameters, QgsProcessingContext &context, QgsProcessingFeedback *feedback)=0
Runs the algorithm using the specified parameters.
virtual void initAlgorithm(const QVariantMap &configuration=QVariantMap())=0
Initializes the algorithm using the specified configuration.
virtual bool canExecute(QString *errorMessage=nullptr) const
Returns true if the algorithm can execute.
virtual QString name() const =0
Returns the algorithm name, used for identifying the algorithm.
Contains information about the context in which a processing algorithm is executed.
Base class for providing feedback from a processing algorithm.
Mesh - vertices, edges and faces.
