@API(status=EXPERIMENTAL, since="5.0") public interface ArgumentConverter
ArgumentConverteris an abstraction that allows an input object to be converted to an instance of a different class.
Implementations must provide a no-args constructor and should not make any assumptions on when they are instantiated or how often they are called. Since instances may potentially be cached and called from different threads they should be thread-safe and designed to be used as singletons.
