@Documented @Retention(value=RUNTIME) @Target(value=TYPE_USE) @TargetLocations(value={RECEIVER,PARAMETER,RETURN}) @SubtypeOf(value=GuardedByUnknown.class) public @interface GuardSatisfied
x has type @GuardSatisfied, then all lock expressions for x's value are held.
Written on a formal parameter (including the receiver), this annotation indicates that the
@GuardedBy type for the corresponding actual argument at the method call site
is unknown at the method definition site, but any lock expressions that guard it are known to be
held prior to the method call.
For example, the formal parameter of the String copy constructor, String(String
s), is annotated with @GuardSatisfied. This requires that all locks guarding the actual
argument are held when the constructor is called. However, the definition of the constructor does
not need to know what those locks are (and it cannot know, because the constructor can be called
by arbitrary code).
