## [Java] Annotation Type Invariant

- groovy.contracts.Invariant

-     @Retention(RetentionPolicy.RUNTIME)
      @Target(ElementType.TYPE)
      @Incubating
      @ClassInvariant
      @AnnotationProcessorImplementation(ClassInvariantAnnotationProcessor.class)
      public @interface Invariant

  Represents a class-invariant.

  The class-invariant defines assertions holding during the entire objects life-time.

  Class-invariants are verified at runtime at the following pointcuts:

  - after a constructor call
  - before a method call
  - after a method call

  Whenever a class has a parent which itself specifies a class-invariant, that class-invariant expression is combined with the actual class's invariant (by using a logical AND).
