Base class for providing feedback from a processing algorithm.
virtual QString name() const =0
Returns the algorithm name, used for identifying the algorithm.
virtual QString group() const
Returns the name of the group this algorithm belongs to.
virtual QStringList tags() const
Returns a list of tags which relate to the algorithm, and are used to assist users in searching for s...
virtual QString shortHelpString() const
Returns a localised short helper string for the algorithm.
Abstract base class for processing algorithms.
virtual void initAlgorithm(const QVariantMap &configuration=QVariantMap())=0
