Interface JsonType<T>

All Superinterfaces:
JsonView<T>
public interface JsonType<T> extends JsonView<T>
Provides API to serialise a type to and from JSON.

JsonType provides the main API used to read and write json.

fromJson

Read json content from: String, byte[], Reader, InputStream, JsonReader 



  JsonType<Customer> customerType = jsonb.type(Customer.class);

  Customer customer = customerType.fromJson(content);

toJson

Write json content to: String, byte[], Writer, OutputStream, JsonWriter 



  JsonType<Customer> customerType = jsonb.type(Customer.class);

  String asJson = customerType.toJson(customer);

Moshi note: JsonType does not exist in Moshi and has been added to provide a slightly nicer API to use than JsonAdapter.
