* Enabling this feature will only change the serialized form if the map key is
* a complex type (i.e. non-primitive) in its <strong>serialized</strong> JSON
* form. The default implementation of map serialization uses {@code toString()}
* on the key; however, when this is called then one of the following cases
* apply:
*
* <h3>Maps as JSON objects</h3>
* For this case, assume that a type adapter is registered to serialize and
* deserialize some {@code Point} class, which contains an x and y coordinate,
* to/from the JSON Primitive string value {@code "(x,y)"}. The Java map would
* then be serialized as a {@link JsonObject}.
*
* <p>Below is an example:
* <pre> {@code
* Gson gson = new GsonBuilder()
* .register(Point.class, new MyPointTypeAdapter())
* .enableComplexMapKeySerialization()
* .create();
*
* Map<Point, String> original = new LinkedHashMap<Point, String>();
* original.put(new Point(5, 6), "a");
* original.put(new Point(8, 8), "b");
* System.out.println(gson.toJson(original, type));
* }</pre>
* The above code prints this JSON object:<pre> {@code
* {
* "(5,6)": "a",
* "(8,8)": "b"
* }
* }</pre>
*
* <h3>Maps as JSON arrays</h3>
* For this case, assume that a type adapter was NOT registered for some
* {@code Point} class, but rather the default Gson serialization is applied.
* In this case, some {@code new Point(2,3)} would serialize as {@code
* {"x":2,"y":5}}.
*
* <p>Given the assumption above, a {@code Map<Point, String>} will be
* serialize as an array of arrays (can be viewed as an entry set of pairs).
*
* <p>Below is an example of serializing complex types as JSON arrays:
* <pre> {@code
* Gson gson = new GsonBuilder()
* .enableComplexMapKeySerialization()
* .create();
*
* Map<Point, String> original = new LinkedHashMap<Point, String>();
* original.put(new Point(5, 6), "a");
* original.put(new Point(8, 8), "b");
* System.out.println(gson.toJson(original, type));
* }
*
* The JSON output would look as follows:
* <pre> {@code
* [
* [
* {
* "x": 5,
* "y": 6
* },
* "a"
* ],
* [
* {
* "x": 8,
