Annotation Type AutoValue

@Retention(value=SOURCE)
@Target(value=TYPE)
public @interface AutoValue

Specifies that AutoValue should generate an implementation class for the annotated abstract class, implementing the standard Object methods like equals to have conventional value semantics. A simple example:

   @AutoValue
   abstract class Person {
     static Person create(String name, int id) {
       return new AutoValue_Person(name, id);
     }

     abstract String name();
     abstract int id();
   }

Element Detail

cacheHashCode

public abstract boolean cacheHashCode

Specifies whether the generated class should cache each instance's hashCode value in a field once it is first computed. Note: most classes should have no need of this behavior and should omit this parameter entirely. Use only if certain of its performance benefit to your application.

Warning: while using mutable field types is strongly discouraged in general, using this feature makes it especially dangerous.

Default:

false
