CAttributeFeatures Class Reference

---

Detailed Description

Implements attributed features, that is in the simplest case a number of (attribute, value) pairs.

For example

x[0...].attr1 = <value(s)> x[0...].attr2 = <value(s)>.

A more complex example would be nested structures x[0...].attr1[0...].subattr1 = ..

This might be used to represent (attr, value) pairs, simple structures, trees ...
