writeTo

public void writeTo(Argument<SystemFile> type,
 MediaType mediaType,
 SystemFile file,
 MutableHeaders outgoingHeaders,
 OutputStream outputStream)
             throws CodecException

Description copied from interface: MessageBodyWriter

Writes an object to the given output stream.

Specified by:

writeTo in interface MessageBodyWriter<SystemFile>

Parameters:

type - The type

mediaType - The media type

file - The object to write

outgoingHeaders - The HTTP headers

outputStream - The output stream

Throws:

CodecException - If an error occurs decoding

write

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

Description copied from interface: ResponseBodyWriter

Writes an object as a ByteBodyHttpResponse.

Specified by:

write in interface ResponseBodyWriter<SystemFile>

Parameters:

bodyFactory - The buffer factory

request - The request

httpResponse - The response

type - The response body type

mediaType - The media type

object - The object to write

Returns:

A ByteBodyHttpResponse with the response bytes
