Annotation Type PolyIndex

@Documented
 @Target(value={TYPE_USE,TYPE_PARAMETER})
 @Retention(value=RUNTIME)
 @PolymorphicQualifier(value=UpperBoundUnknown.class)
public @interface PolyIndex

A polymorphic qualifier for the Lower Bound and Upper Bound type systems.

Writing @PolyIndex is equivalent to writing @PolyUpperBound @PolyLowerBound, and that is how it is treated internally by the checker. Thus, if you write an @PolyIndex annotation, you might see warnings about @PolyUpperBound or @PolyLowerBound.
