AutoValue: With Extension

An extension for Google's AutoValue that implements "with-er" methods for AutoValue objects.

Note: This is an early version that requires the extension support currently in AutoValue 1.2-SNAPSHOT.

Usage

Include auto-value-with in your project and "with-er" methods to your auto-value objects.

@AutoValue public abstract class User {
  abstract String id();
  abstract String name();
  abstract String email();

  abstract User withEmail(String email);

  // you can also use multiple
  abstract User withNameAndEmail(String name, String email);
}

The extension will generate an implementation of withEmail(String) that returns a new instance of User with the given email.

By convention "with-er" methods have to use with as prefix and use the exact property name for both method name and parameter name.
