    public SourceHttpMessageConverter()

Method Detail

### 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:
    `IOException` - in case of I/O errors

    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.

  Overrides:
    `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

### writeToResult

    protected void writeToResult(T t,
                                 HttpHeaders headers,
                                 Result result)
                          throws IOException

  Description copied from class: `AbstractXmlHttpMessageConverter`
  Abstract template method called from `AbstractXmlHttpMessageConverter.writeInternal(Object, HttpOutputMessage)`.

  Specified by:
    `writeToResult` in class `AbstractXmlHttpMessageConverter<T extends Source>`
  Parameters:
    `t` - the object to write to the output message
    `headers` - the HTTP output headers
