                         MimeType mimeType)
```
    Description copied from interface: Decoder
    Whether the decoder supports the given target element type and the MIME type of the source stream.
    Specified by:
    canDecode in interface Decoder<T>
    Parameters:
    elementType - the target element type for the output stream
    mimeType - the mime type associated with the stream to decode (can be null if not specified)

    Description copied from interface: Decoder
    Decode a DataBuffer input stream into a Mono of T.
    Specified by:
    decodeToMono in interface Decoder<T>
    Parameters:
    inputStream - the DataBuffer input stream to decode
    elementType - the expected type of elements in the output stream; this type must have been previously passed to the Decoder.canDecode(org.springframework.core.ResolvableType, org.springframework.util.MimeType) method and it must have returned true.
    mimeType - the MIME type associated with the input stream (optional)
    hints - additional information about how to do encode
    Returns:
    the output stream with the decoded element
