Annotation Interface Unique
@Documented
@Retention(RUNTIME)
@Target({TYPE_USE,TYPE_PARAMETER})
@SubtypeOf(MaybeAliased.class)
public @interface Unique
An expression with this type has no aliases. In other words, no other expression, evaluated at
the same program point, would evaluate to the exact same object value.
A constructor's return type should be annotated with @Unique if the constructor does
not leak references to the constructed object. For example, the String() constructor
return type is annotated as @Unique.
