- org.springframework.core.codec.AbstractDecoder<T>
- - org.springframework.core.codec.AbstractDataBufferDecoder<DataBuffer>
  - - org.springframework.core.codec.DataBufferDecoder

所有已实现的接口:
Decoder<DataBuffer>
```
public class DataBufferDecoder
extends AbstractDataBufferDecoder<DataBuffer>
```
Simple pass-through decoder for DataBuffers.
Note: The data buffers should be released via DataBufferUtils.release(DataBuffer) after they have been consumed. In addition, if using Flux or Mono operators such as flatMap, reduce, and others that prefetch, cache, and skip or filter out data items internally, please add doOnDiscard(PooledDataBuffer.class, DataBufferUtils::release) to the composition chain to ensure cached data buffers are released prior to an error or cancellation signal.

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<DataBuffer>
    覆盖:
    canDecode 在类中 AbstractDecoder<DataBuffer>
    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<DataBuffer> decode(org.reactivestreams.Publisher<DataBuffer> input,
                                                      ResolvableType elementType,

                                                      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<DataBuffer>
    覆盖:
    decode 在类中 AbstractDataBufferDecoder<DataBuffer>
    参数:
    input - 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 DataBuffer decode(DataBuffer buffer,
                         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:
    buffer - 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
