• canDecode

  public boolean canDecode​(ResolvableType elementType,
                           @Nullable
                           MimeType mimeType)

  从接口复制的说明: Decoder
  Whether the decoder supports the given target element type and the MIME type of the source stream.

  指定者:

  canDecode 在接口中 Decoder<Resource>

  覆盖:

  canDecode 在类中 AbstractDecoder<Resource>

  参数:

  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)

  返回:

  true if supported, false otherwise

• decode

  public reactor.core.publisher.Flux<Resource> decode​(org.reactivestreams.Publisher<DataBuffer> inputStream,
                                                      ResolvableType elementType,
                                                      @Nullable
                                                      MimeType mimeType,
                                                      @Nullable
                                                      Map<String,​Object> hints)

  从接口复制的说明: Decoder
  Decode a DataBuffer input stream into a Flux of T.

  指定者:

  decode 在接口中 Decoder<Resource>

  覆盖:

  decode 在类中 AbstractDataBufferDecoder<Resource>

  参数:

  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

  返回:

  the output stream with decoded elements

• decode

  public Resource decode​(DataBuffer dataBuffer,
                         ResolvableType elementType,
                         @Nullable
                         MimeType mimeType,
                         @Nullable
                         Map<String,​Object> hints)

  从接口复制的说明: 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.

  参数:

  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

  返回:

  the decoded value, possibly null
