## 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
  Classification/example_feature.cpp.
