Examples of org.openstreetmap.josm.data.osm.TagCollection

org.openstreetmap.josm.data.osm.TagCollection
TagCollection is a collection of tags which can be used to manipulate tags managed by {@link org.openstreetmap.josm.data.osm.OsmPrimitive}s. A TagCollection can be created:
- from the tags managed by a specific {@link org.openstreetmap.josm.data.osm.OsmPrimitive} with {@link #from(org.openstreetmap.josm.data.osm.Tagged)}
- from the union of all tags managed by a collection of {@link org.openstreetmap.josm.data.osm.OsmPrimitive}s with {@link #unionOfAllPrimitives(java.util.Collection)}
- from the union of all tags managed by a {@link org.openstreetmap.josm.data.osm.DataSet} with {@link #unionOfAllPrimitives(org.openstreetmap.josm.data.osm.DataSet)}
- from the intersection of all tags managed by a collection of primitives with {@link #commonToAllPrimitives(java.util.Collection)}
It provides methods to query the collection, like {@link #size()}, {@link #hasTagsFor(String)}, etc. Basic set operations allow to create the union, the intersection and the difference of tag collections, see {@link #union(org.openstreetmap.josm.data.osm.TagCollection)}, {@link #intersect(org.openstreetmap.josm.data.osm.TagCollection)}, and {@link #minus(org.openstreetmap.josm.data.osm.TagCollection)}.
