canEncode

public boolean canEncode(ResolvableType elementType,
                         @Nullable
                         MimeType mimeType)

Description copied from interface: Encoder

Whether the encoder supports the given source element type and the MIME type for the output stream.

Specified by:

canEncode in interface Encoder<byte[]>

Overrides:

canEncode in class AbstractEncoder<byte[]>

Parameters:

elementType - the type of elements in the source stream

mimeType - the MIME type for the output stream (can be null if not specified)

Returns:

true if supported, false otherwise

encode

public reactor.core.publisher.Flux<DataBuffer> encode(org.reactivestreams.Publisher<? extends byte[]> inputStream,
                                                      DataBufferFactory bufferFactory,

                                                      Map<String,Object> hints)

Description copied from interface: Encoder

Encode a stream of Objects of type T into a DataBuffer output stream.

Parameters:

inputStream - the input stream of Objects to encode. If the input should be encoded as a single value rather than as a stream of elements, an instance of Mono should be used.

bufferFactory - for creating output stream DataBuffer's

elementType - the expected type of elements in the input stream; this type must have been previously passed to the Encoder.canEncode(org.springframework.core.ResolvableType, org.springframework.util.MimeType) method and it must have returned true.

mimeType - the MIME type for the output stream (optional)

hints - additional information about how to do encode

Returns:

the output stream
