Method Details

getType

public Argument<Writable> getType()

Specified by:

getType in interface TypedMessageBodyHandler<Writable>

Specified by:

getType in interface TypedMessageBodyReader<Writable>

Specified by:

getType in interface TypedMessageBodyWriter<Writable>

Returns:

The body type.

isBlocking

public boolean isBlocking()

Description copied from interface: MessageBodyWriter

true iff this closure can do a blocking read on the object it receives. For example, if this closure writes from an InputStream, that operation may be blocking and this method returns true.
Note that even when this is false, MessageBodyWriter.writeTo(Argument, MediaType, Object, MutableHeaders, OutputStream) may still block because the OutputStream that is passed as the write destination may still block.

Specified by:

isBlocking in interface MessageBodyWriter<Writable>

Returns:

Whether this writer may block

writeTo

public void writeTo(Argument<Writable> type,
 MediaType mediaType,
 Writable object,
 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<Writable>

Parameters:

type - The type

mediaType - The media type

object - The object to write

outgoingHeaders - The HTTP headers

outputStream - The output stream

Throws:

CodecException - If an error occurs decoding

readChunked

public Publisher<? extends Writable> readChunked(Argument<Writable> type,
 MediaType mediaType,
 Headers httpHeaders,
 Publisher<ByteBuffer<?>> input)

Specified by:

readChunked in interface ChunkedMessageBodyReader<Writable>

read

public Writable read(Argument<Writable> type,
 MediaType mediaType,
 Headers httpHeaders,
 ByteBuffer<?> byteBuffer)
              throws CodecException

Description copied from interface: MessageBodyReader

Specified by:

read in interface MessageBodyReader<Writable>

Parameters:

read

public Writable read(Argument<Writable> type,
 MediaType mediaType,
 Headers httpHeaders,
 InputStream inputStream)
              throws CodecException

Description copied from interface: MessageBodyReader

Reads an object from the given byte buffer.

Specified by:

read in interface MessageBodyReader<Writable>

Parameters:
