QgsClassificationMethod
QgsClassificationMethod is an abstract class for implementations of classification methods.
Definition: qgsclassificationmethod.h:88
QgsClassificationMethod::icon
virtual QIcon icon() const
The icon of the method.
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
QgsClassificationEqualInterval
QgsClassificationEqualInterval is an implementation of QgsClassificationMethod for equal intervals.
Definition: qgsclassificationequalinterval.h:28
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.
qgsclassificationmethod.h
QgsClassificationMethod::name
virtual QString name() const =0
The readable and translate name of the method.
