Annotation Type CheckReturnValue

@Documented
@Target({METHOD,CONSTRUCTOR,TYPE,PACKAGE})
@Retention(RUNTIME)
public @interface CheckReturnValue

Indicates that the return value of the annotated method must be checked. An error is triggered when one of these methods is called but the result is not used.

@CheckReturnValue may be applied to a class or package to indicate that all methods in that class (including indirectly; that is, methods of inner classes within the annotated class) or package must have their return values checked. For convenience, we provide an annotation, CanIgnoreReturnValue, to exempt specific methods or classes from this behavior.
