Definition

Abstract class describing a classification feature that associates a scalar value to each item of the classification input.

Examples
Classification/example_feature.cpp.

Public Member Functions

const std::string & name () const
 returns the name of the feature (initialized to abstract_feature for Feature_base).
 
void set_name (const std::string &name)
 changes the name of the feature.
 
virtual float value (std::size_t index)=0
 returns the value taken by the feature for at the item for the item at position index.
 

Member Function Documentation

◆ value()

virtual float CGAL::Classification::Feature_base::value ( std::size_t  index)
pure virtual

returns the value taken by the feature for at the item for the item at position index.

This method must be implemented by inherited classes.

Examples
