Example 1 with JsonException

use of jmri.server.json.JsonException in project JMRI by JMRI.

the class JsonUtil method setConsist.

/**
     * 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 locale  the locale to throw exceptions in
     * @param address the consist address
     * @param data    the consist as a JsonObject
     * @throws jmri.server.json.JsonException if no ConsistManager is available
