    - #### supports

          public boolean supports(Class<?> clazz)

      Description copied from class: `AbstractHttpMessageConverter`
      Indicates whether the given class is supported by this converter.
      Specified by:
        `supports` in class `AbstractHttpMessageConverter<T extends Source>`
      Parameters:
        `clazz` - the class to test for support
      Returns:
        `true` if supported; `false` otherwise

    - #### readFromSource

          protected T readFromSource(Class clazz,
                         HttpHeaders headers,
                         Source source)
                                             throws IOException

      Description copied from class: `AbstractXmlHttpMessageConverter`
      Abstract template method called from `AbstractHttpMessageConverter.read(Class, HttpInputMessage)`.
      Specified by:
        `readFromSource` in class `AbstractXmlHttpMessageConverter<T extends Source>`
      Parameters:
        `clazz` - the type of object to return
        `headers` - the HTTP input headers
        `source` - the HTTP input body
      Returns:
        the converted object
      Throws:

    - #### getContentLength

          protected Long getContentLength(T t,
                              MediaType contentType)

      Description copied from class: `AbstractHttpMessageConverter`
      Returns the content length for the given type.

      By default, this returns `null`, meaning that the content length is unknown. Can be overridden in subclasses.

        `getContentLength` in class `AbstractHttpMessageConverter<T extends Source>`
      Parameters:
        `t` - the type to return the content length for
      Returns:
        the content length, or `null` if not known
