JsonObject and JsonArray

Generic JSON objects

Default object types of parsed JSON inputs are Map and List. While this can be enough, sometimes you want a more developer-friendly way to navigate the returned object, especially nested values - you keep casting all over the code. Jodd JSON comes with two nice classes: JsonObject and JsonArray that can be used instead of defaults. They are quite convenient to work with JSON structure.

Here is an example of the usage:

JsonObject jo = JsonParser.create().parseAsJsonObject("{ ... }");

Integer i = jo.getInteger("key");
JsonObject child = jo.getJsonObject("child");
JsonArray ja = jo.getJsonArray("arr");
Double d = ja.getDouble(ndx);


Both JsonObject and JsonArray may be used for serialization, too. You can use them to construct the JSON structure and then serialize it as usual.

Binary values

JsonObject is able to read and write binaries i.e. byte[]. Of course, JSON format does not support the binary types, hence the input array is encoded to Base64. Similarly,the Base64 field can be read as binary and convert into the byte[].
