  • Method Details

    • getInputStream

      public InputStream getInputStream() throws IOException
      Returns an input stream from this MimePart.

      This method applies the appropriate transfer-decoding, based on the Content-Transfer-Encoding attribute of this MimePart. Thus the returned input stream is a decoded stream of bytes.

      This implementation obtains the raw content from the Part using the getContentStream() method and decodes it using the MimeUtility.decode() method.

      Specified by:
      getInputStream in interface DataSource
      Returns:
      decoded input stream
      Throws:
      IOException - for failures creating the InputStream
