extends Object

Method Summary

Modifier and Type	Method and Description
static List<String>	collectValuesNamed(com.squareup.moshi.JsonReader reader, String name)
static com.squareup.moshi.JsonReader	enterPath(com.squareup.moshi.JsonReader reader, String path)
static com.squareup.moshi.JsonReader	enterPath(com.squareup.moshi.JsonReader reader, String path1, String path2) This saves you from having to define nested types to read a single value

Method Detail

enterPath

@Nullable
public static com.squareup.moshi.JsonReader enterPath(com.squareup.moshi.JsonReader reader,
                                                                String path1,
                                                                String path2)
                                                         throws IOException

This saves you from having to define nested types to read a single value

Instead of defining two types like this, and double-checking null..

 class Response {
   Message message;
 }
 class Message {
   String status;
 }
 JsonAdapter<Response> adapter = moshi.adapter(Response.class);
 Message message = adapter.fromJson(body.source());
 if (message != null && message.status != null) throw new IllegalStateException(message.status);
 

You can advance to the field directly.

 JsonReader status = enterPath(JsonReader.of(body.source()), "message", "status");
 if (status != null) throw new IllegalStateException(status.nextString());
 

Throws:

IOException
