Bit field for OSM entity types.

Enumeration Type Documentation

type

enum osmium::osm_entity_bits::type : unsigned char

Describes zero or more OSM entities.

Usage:

osmium::osm_entity_bits::type entities = osmium::osm_entity_bits::node | osmium::osm_entity_bits::way;
 
entities |= osmium::osm_entity_bits::relation;
 
assert(entities & osmium::osm_entity_bits::object);
 
assert(! (entities & osmium::osm_entity_bits::changeset));
