How to use

getNumberOfTags

method

in

de.topobyte.osm4j.core.model.iface.OsmEntity

public static boolean hasTag(OsmEntity entity, String key, String value) {
  for (int i = 0; i < entity.getNumberOfTags(); i++) {
    OsmTag tag = entity.getTag(i);
    if (tag.getKey().equals(key) && tag.getValue().equals(value)) {
      return true;
    }
  }
  return false;
}

tags.lengths[row] = entity.getNumberOfTags(); // number of key/value pairings
tags.childCount += tags.lengths[row];
tags.keys.ensureSize(tags.childCount, tags.offsets[row] != 0);
