Definition: qgsclassificationmethod.h:153
QgsClassificationMethod::valuesRequired
virtual bool valuesRequired() const
Returns if the method requires values to calculate the classes If not, bounds are sufficient.
Definition: qgsclassificationmethod.h:177
QgsClassificationMethod::clone
virtual QgsClassificationMethod * clone() const =0
Returns a clone of the method.
QgsClassificationMethod::id
virtual QString id() const =0
The id of the method as saved in the project, must be unique in registry.
QgsClassificationFixedInterval
Implementation of a fixed interval classification.
