Annotation Interface PostConstructionInitializer.InitializedParam

Enclosing class:

PostConstructionInitializer

@Target(PARAMETER)
@Retention(RUNTIME)
public static @interface PostConstructionInitializer.InitializedParam

Marks a specific parameter in a static initializer method as being the initialized object. This disambiguates situations where static initializer methods accept multiple arguments of the same initialize-required type; for example:

class Foo {
  @PostConstructionInitializer
  static void copy(Foo src, @InitializedParam Foo dst) {
    // ...
  }
}

Static initializer methods must have a parameter of the exact type that defines the static method.

interface I {
  @PostConstructionInitializer
  static void init(I object) { ... }
}

class Foo implements I {
  @PostConstructionInitializer
  static void initFoo(Foo foo) { ... } // OK

  @PostConstructionInitializer
  static void initI(I object) { ... } // ERROR: I is not Foo

  @PostConstructionInitializer
  static void initOther(SomeOtherType o) { ... } // ERROR: SomeOtherType is not Foo
}
