    • convert

      @Nullable T convert(S source)
      Convert the source object of type S to target type T.
      参数:
      source - the source object to convert, which must be an instance of S (never null)
      返回:

    • andThen

      default <U> Converter<S,U> andThen(Converter<? super T,? extends U> after)
      Construct a composed Converter that first applies this Converter to its input, and then applies the after Converter to the result.
      类型参数:
      U - the type of output of both the after Converter and the composed Converter
      参数:
      after - the Converter to apply after this Converter is applied
      返回:
      a composed Converter that first applies this Converter and then applies the after Converter
