Examples of org.json.JSONObject.accumulate()

org.json.JSONObject.accumulate()
Accumulate values under a key. It is similar to the put method except that if there is already an object stored under the key then a JSONArray is stored under the key to hold all of the accumulated values. If there is already a JSONArray, then the new value is appended to it. In contrast, the put method replaces the previous value. If only one value is accumulated that is not a JSONArray, then the result will be the same as using put. But if multiple values are accumulated, then the result will be like append. @param key A key string. @param value An object to be accumulated under the key. @return this. @throws JSONException If the value is an invalid number or if the key is null.
