Any method written using a polymorphic type qualifier conceptually has two or more versions — one version for each qualifier in the qualifier hierarchy. In each version of the method, all instances of the polymorphic type qualifier are replaced by one of the other type qualifiers.

| public Class Indicates which type system this annotation refers to (optional, and usually unnecessary). When multiple type hierarchies are supported by a single type system, then each polymorphic qualifier needs to indicate which sub-hierarchy it belongs to. Do so by passing the top qualifier from the given hierarchy.
