Class OSMSpecifier

java.lang.Object

org.opentripplanner.graph_builder.module.osm.OSMSpecifier

public class OSMSpecifier
extends Object

Specifies a class of OSM tagged entities (e.g. ways) by a list of tags and their values (which may be wildcards). The OSMSpecifier which matches the most tags on an OSM entity will win. In the event that several OSMSpecifiers match the same number of tags, the one that does so using less wildcards will win. For example, if one OSMSpecifier has the tags (highway=residential, cycleway=*) and another has (highway=residential, surface=paved) and a way has the tags (highway=residential, cycleway=lane, surface=paved) the second OSMSpecifier will be applied to that way (2 exact matches beats 1 exact match and a wildcard match).

matchScores

public P2<Integer> matchScores(OSMWithTags match)

Calculates a pair of scores expressing how well an OSM entity's tags match this specifier. Tags in this specifier are matched against those for the left and right side of the OSM way separately. See: http://wiki.openstreetmap.org/wiki/Forward_%26_backward,_left_%26_right TODO: we should probably support forward/backward as well. TODO: simply count the number of full, partial, and wildcard matches instead of using a scoring system.

Parameters:

match - an OSM tagged object to compare to this specifier

matchScore

public int matchScore(OSMWithTags match)

Calculates a score expressing how well an OSM entity's tags match this specifier. This does exactly the same thing as matchScores but without regard for :left and :right.

addTag

public void addTag(String key,
                   String value)

toString

public String toString()

Overrides:
