QString id() const override
The id of the method as saved in the project, must be unique in registry.
QgsClassificationMethod * clone() const override
Returns a clone of the method.
QString name() const override
The readable and translate name of the method.

QgsClassificationMethod is an abstract class for implementations of classification methods.
void copyBase(QgsClassificationMethod *c) const
Copy the parameters (shall be used in clone implementation)
As part of the API refactoring and improvements which landed in the Processing API was substantially reworked from the x version This was done in order to allow much of the underlying Processing framework to be ported into c
