    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<Resource>
    Overrides:
    canDecode in class AbstractDecoder<Resource>
    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)
    Returns:
    true if supported, false otherwise
  - decode

```
    Description copied from interface: Decoder
    Decode a DataBuffer input stream into a Flux of T.
    Specified by:
    decode in interface Decoder<Resource>
    Overrides:
    decode in class AbstractDataBufferDecoder<Resource>
    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 decoded elements
  - decode
```
public Resource decode(DataBuffer dataBuffer,
                       ResolvableType elementType,
                       @Nullable
                       MimeType mimeType,
                       @Nullable
                       Map<String,Object> hints)
```
    Description copied from interface: Decoder
    Decode a data buffer to an Object of type T. This is useful for scenarios, that distinct messages (or events) are decoded and handled individually, in fully aggregated form.
    Parameters:
    dataBuffer - the DataBuffer to decode
    elementType - the expected output type
    mimeType - the MIME type associated with the data
    hints - additional information about how to do encode
    Returns:
    the decoded value, possibly null
