write

public ByteBodyHttpResponse<?> write(@NonNull
 @NonNull ByteBodyFactory bodyFactory,
 HttpRequest<?> request,
 MutableHttpResponse<StreamedFile> outgoingResponse,
 Argument<StreamedFile> type,
 MediaType mediaType,
 StreamedFile object)
                              throws CodecException

Description copied from interface: ResponseBodyWriter

Writes an object as a ByteBodyHttpResponse.

Specified by:

write in interface ResponseBodyWriter<StreamedFile>

Parameters:

bodyFactory - The buffer factory

request - The request

outgoingResponse - The response

type - The response body type

mediaType - The media type

object - The object to write

Returns:

A ByteBodyHttpResponse with the response bytes
