the class TypeToken method getGenericInterfaces.

/**
   * Returns the generic interfaces that this type directly {@code implements}. This method is
   * similar but different from {@link Class#getGenericInterfaces()}. For example, {@code new

   * {@code new TypeToken<Iterable<String>>() {}}; while {@code List.class.getGenericInterfaces()}
   * will return an array that contains {@code Iterable<T>}, where the {@code T} is the type
   * variable declared by interface {@code Iterable}.
   *
   * <p>If this type is a type variable or wildcard, its upper bounds are examined and those that
   * are either an interface or upper-bounded only by interfaces are returned. This means that the
   * returned types could include type variables too.
