code: public static boolean hasType(Type valueType)
    {
      return valueType instanceof Class ? instance.hasClassConverter((Class<?>)valueType) : false;
    }
docs: Convenient way to test for converter support, see {@link #hasClassConverter(Class)}. Note that this predicate
  variant accepts {@link Type} as parameter to simplify integration with user code but always returns false if type
  is not a {@link Class}.
  
  @param valueType value type to check for conversion support.
  @return true if value type has registered converter.
