START_ARRAY is returned when encountering '[' which signals starting of an Array value

Usage

From source file:com.google.openrtb.json.OpenRtbJsonUtils.java

/**
 * Starts an Array, skipping the '[' token, and if necessary a field name before it.
 *//*from  w  ww. j  a v a 2s .com*/
public static void startArray(JsonParser par) throws IOException {
    JsonToken token = par.getCurrentToken();
    if (token == null || token == JsonToken.FIELD_NAME) {
        token = par.nextToken();
    }
    if (token == JsonToken.START_ARRAY) {
        par.nextToken();
    } else {
        throw new JsonParseException(par, "Expected start of array");
    }
