@Override
protected void init(IndexSchema schema, Map<String, String> args) {
    super.init(schema, args);

    //Solr expects us to remove the parameters we've used.
    MapListener<String, String> argsWrap = new MapListener<String, String>(args);
    grid = SpatialPrefixTreeFactory.makeSPT(argsWrap, schema.getResourceLoader().getClassLoader(), ctx);
    args.keySet().removeAll(argsWrap.getSeenKeys());

    String v = args.remove(SpatialArgsParser.DIST_ERR_PCT);
    if (v != null)
        distErrPct = Double.valueOf(v);

    v = args.remove(DEFAULT_FIELD_VALUES_ARRAY_LEN);
    if (v != null)
        defaultFieldValuesArrayLen = Integer.valueOf(v);
