void typedef void boost::geometry::traits::tag< Geometry, Enable >::type type

Traits class to attach a tag to a geometry.

All geometries should implement a traits::tag<G>::type metafunction to indicate their own geometry type.

# Geometries:

- all geometries

# Specializations should provide:

- typedef XXX_tag type; (point_tag, box_tag, ...)
