public ByteBuf decode(DataBuffer dataBuffer, ResolvableType elementType, MimeType mimeType, Map<String, Object> hints)

Overrides default org.springframework.core.codec.Decoder.decode.

Doc from org.springframework.core.codec.Decoder.decode.

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:DataBuffer

the DataBuffer to decode

elementType:ResolvableType

the expected output type

mimeType:MimeType

the MIME type associated with the data

hints:Map<String, Object>

additional information about how to do decode

Returns:ByteBuf

the decoded value, possibly null
