Examples with ADDRESS jmri.server.json.JSON.ADDRESS used on opensource projects

Example 1 with ADDRESS

use of jmri.server.json.JSON.ADDRESS in project JMRI by JMRI.

the class JsonConsistHttpService method doPost.

/**
     * Change the properties and locomotives of a consist.
     *
     * This method takes as input the JSON representation of a consist as
     * provided by {@link #getConsist(Locale, jmri.DccLocoAddress) }.
     *
     * If present in the JSON, this method sets the following consist
     * properties:
     * <ul>
     * <li>consistID</li>
     * <li>consistType</li>
     * <li>locomotives (<em>engines</em> in the JSON representation)<br>
     * <strong>NOTE</strong> Since this method adds, repositions, and deletes
     * locomotives, the JSON representation must contain <em>every</em>
     * locomotive that should be in the consist, if it contains the engines
     * node.</li>
     * </ul>
     *
     * @param type   the JSON message type
     * @param locale the locale to throw exceptions in
     * @param name   the consist address, ignored if data contains an
     *               {@value jmri.server.json.JSON#ADDRESS} and
     *               {@value jmri.server.json.JSON#IS_LONG_ADDRESS} nodes
     * @param data   the consist as a JsonObject
     * @return the JSON representation of the Consist
     * @throws jmri.server.json.JsonException if there is no consist manager
     *                                        (code 503), the consist does not
     *                                        exist (code 404), or the consist
     *                                        cannot be saved (code 500).
