      Parameters:
      content - The content to decode.

      Returns:
      instance of Object according to the supplied MediaType "type" parameter, or if no type is present, the object itself.

    • decodeOctetStream

      @Deprecated public static byte[] decodeOctetStream(Object input, MediaType octetStream)
      Deprecated.
      Since 13.0, without replacement.
      Decode a octet-stream content that is not a byte[]. For this, it uses a special param called "encoding" in the "application/octet-stream" MediaType. The "encoding" param supports only the "hex" value that represents an octet-stream as a hexadecimal representation, for example "0xdeadbeef". In the absence of the "encoding" param, it will assume base64 encoding.
      Parameters:
      input - Object representing the binary content.
      octetStream - The MediaType describing the input.
      Returns:
      a byte[] with the decoded content.
