Definition

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

Examples:

Classification/example_feature.cpp.

	Returns the value taken by the feature for at the item for the item at position index. More...

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.
