Examples with JSONArray org.json_voltpatches.JSONArray used on opensource projects

Example 1 with JSONArray

use of org.json_voltpatches.JSONArray in project voltdb by VoltDB.

the class AbstractExpression method loadSortListFromJSONArray.

/**
     * Load two lists from a JSONObject.
     * One list is for sort expressions and the other is for sort directions.
     * The lists are cleared before they are filled in.
     * This is the inverse of toJSONArrayFromSortList.
     *
     * The JSONObject should be in object state, not array state.
     * It should have a member named SORT_COLUMNS,
     * which is an array with the <expression, direction> pairs.
     * Sometimes the sort directions are not needed.
     * For example, when deserializing
     *
     * @param sortExpressions The container for the sort expressions.
     * @param sortDirections The container for the sort directions.  This may
     *                       be null if we don't care about directions.  If there
     *                       are no directions in the list this will be empty.
     * @param jarray
     * @throws JSONException
