    • setMaxInMemorySize

      public void setMaxInMemorySize(int byteCount)
      Set the max number of bytes that can be buffered by this decoder. This is either the size of the entire input when decoding as a whole, or the size of one top-level JSON object within a JSON stream. When the limit is exceeded, DataBufferLimitException is raised.

      By default this is set to 256K.

      参数:
      byteCount - the max number of bytes to buffer, or -1 for unlimited

    • getMaxInMemorySize

      public int getMaxInMemorySize()
      Return the configured byte count limit.

    • canDecode

      public boolean canDecode(cn.taketoday.core.ResolvableType elementType, @Nullable cn.taketoday.util.MimeType mimeType)
      指定者:
      canDecode 在接口中 cn.taketoday.core.codec.Decoder<Object>

    • decode

      指定者:
      decode 在接口中 cn.taketoday.core.codec.Decoder<Object>

    • processInput

      protected reactor.core.publisher.Flux<cn.taketoday.core.io.buffer.DataBuffer> processInput(org.reactivestreams.Publisher<cn.taketoday.core.io.buffer.DataBuffer> input, cn.taketoday.core.ResolvableType elementType, @Nullable cn.taketoday.util.MimeType mimeType, @Nullable Map<String,Object> hints)
      Process the input publisher into a flux. Default implementation returns Flux.from(Publisher), but subclasses can choose to customize this behavior.
      参数:
      input - the DataBuffer input stream to process
      elementType - the expected type of elements in the output stream
      mimeType - the MIME type associated with the input stream (optional)
      hints - additional information about how to do encode
      返回:
      the processed flux

      Subclasses can use this method to customize ObjectReader used for reading values.
      参数:
      reader - the reader instance to customize
      elementType - the target type of element values to read to
      hints - a map with serialization hints; the Reactor Context, when available, may be accessed under the key ContextView.class.getName()

      request - the current request
      response - the current response
      返回:
      a Map with hints, possibly empty
