Implementation of a fixed interval classification.
QgsClassificationMethod is an abstract class for implementations of classification methods.
virtual QString id() const =0
The id of the method as saved in the project, must be unique in registry.
virtual std::unique_ptr< QgsClassificationMethod > clone() const =0
Returns a clone of the method.
virtual bool valuesRequired() const
Returns if the method requires values to calculate the classes If not, bounds are sufficient.
virtual QString name() const =0
The readable and translate name of the method.
virtual QIcon icon() const
The icon of the method.
