Definition

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

Examples:
Classification/example_feature.cpp.

◆ 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:
Classification/example_feature.cpp.
