You should write a custom serializer, if - * you are not happy with the default serialization done by Gson. You will also need to register - * this serializer through {@link com.google.gson.GsonBuilder#registerTypeAdapter(Type, Object)}. - * - *

Let us look at example where defining a serializer will be useful. The {@code Id} class - * defined below has two fields: {@code clazz} and {@code value}.

- * - *

- * public class Id<T> {
- *   private final Class<T> clazz;
- *   private final long value;
- *
- *   public Id(Class<T> clazz, long value) {
- *     this.clazz = clazz;
- *     this.value = value;
- *   }
- *
- *   public long getValue() {
- *     return value;
- *   }
- * }
- * 

- * - *

The default serialization of {@code Id(com.foo.MyObject.class, 20L)} will be - * {"clazz":com.foo.MyObject,"value":20}. Suppose, you just want the output to be - * the value instead, which is {@code 20} in this case. You can achieve that by writing a custom - * serializer:

- * - *

- * class IdSerializer implements JsonSerializer<Id>() {
- *   public JsonElement serialize(Id id, Type typeOfId, JsonSerializationContext context) {
- *     return new JsonPrimitive(id.getValue());
- *   }
- * }
- * 

- * - *

You will also need to register {@code IdSerializer} with Gson as follows:

- *
- * Gson gson = new GsonBuilder().registerTypeAdapter(Id.class, new IdSerializer()).create();
- * 
- * - *

New applications should prefer {@link TypeAdapter}, whose streaming API - * is more efficient than this interface's tree API. - * - * @author Inderjeet Singh - * @author Joel Leitch - * - * @param type for which the serializer is being registered. It is possible that a serializer - * may be asked to serialize a specific generic type of the T. - */ -public interface JsonSerializer { - - /** - * Gson invokes this call-back method during serialization when it encounters a field of the - * specified type. - * - *
