AutoMoshi

An AutoValue extension that supports JSON serialization and deserialization through Moshi.

Usage

To opt in to Moshi support, annotate your AutoValue class with @AutoMoshi:

@AutoValue @AutoMoshi abstract class Foo {
  abstract String a();
}

AutoMoshi will generate a JsonAdapter for each @AutoMoshi annotated class. There is generally no need to reference these generated JsonAdapters directly - instead, create an abstract class that implements JsonAdapter.Factory and annotate it with @AutoMoshi.Factory. AutoMoshi will generate a package-private implementation of this factory class, which should be passed to the builder used to create your Moshi instance:

@AutoMoshi.Factory abstract class AdapterFactory implements JsonAdapter.Factory {
  static JsonAdapter.Factory create() {
    return new AutoMoshi_AdapterFactory();
  }
}

Moshi moshi = new Moshi.Builder().add(AdapterFactory.create()).build();

If your factory class is nested, it must be static and must have at least package visibility. The generated implementation will have a name of the form AutoMoshi_Outer_Middle_Inner, where Inner is the name of your factory class:

class Outer {
  @AutoMoshi.Factory static abstract class InnerAdapterFactory implements JsonAdapter.Factory {
    static JsonAdapter.Factory create() {
      return new AutoMoshi_Outer_InnerAdapterFactory();
    }
  }
}

Download

To use AutoMoshi in an Android project, add the following lines to your build.gradle:

dependencies {
  provided 'glass.phil.auto.moshi:auto-moshi-annotations:0.2.0'
  annotationProcessor 'glass.phil.auto.moshi:auto-moshi-processor:0.2.0'
}

As these artifacts are available only at compile time, an explicit dependency on Moshi is also required:

dependencies {
  compile 'com.squareup.moshi:moshi:1.5.0'
}

Releases are published to Maven Central. Snapshots are published to Sonatype's snapshots repository.
