Method Detail

getSize

public long getSize(Object t,
           Class<?> type,
           Type genericType,
           Annotation[] annotations,
           MediaType mediaType)

Description copied from interface: MessageBodyWriter

Originally, the method has been called before writeTo to ascertain the length in bytes of the serialized form of t. A non-negative return value has been used in a HTTP Content-Length header.

As of JAX-RS 2.0, the method has been deprecated and the value returned by the method is ignored by a JAX-RS runtime. All MessageBodyWriter implementations are advised to return -1 from the method. Responsibility to compute the actual Content-Length header value has been delegated to JAX-RS runtime.

Specified by:

getSize in interface MessageBodyWriter<Object>

Parameters:

t - the instance to write

type - the class of instance that is to be written.

genericType - the type of instance to be written. GenericEntity provides a way to specify this information at runtime.

annotations - an array of the annotations attached to the message entity instance.

mediaType - the media type of the HTTP entity.

Returns:

length in bytes or -1 if the length cannot be determined in advance.

isWriteable

public boolean isWriteable(Class<?> type,
                  Type genericType,
                  Annotation[] annotations,
                  MediaType mediaType)

Description copied from interface: MessageBodyWriter

Ascertain if the MessageBodyWriter supports a particular type.

Specified by:

isWriteable in interface MessageBodyWriter<Object>

Parameters:

type - the class of instance that is to be written.

genericType - the type of instance to be written, obtained either by reflection of a resource method return type or via inspection of the returned instance. GenericEntity provides a way to specify this information at runtime.

annotations - an array of the annotations attached to the message entity instance.

mediaType - the media type of the HTTP entity.

Returns:

true if the type is supported, otherwise false.

writeTo

public void writeTo(Object t,
           Class<?> type,
           Type genericType,
           Annotation[] annotations,
           MediaType mediaType,
           MultivaluedMap<String,Object> httpHeaders,
           OutputStream entityStream)
             throws IOException,
                    WebApplicationException

Description copied from interface: MessageBodyWriter

Write a type to an HTTP message. The message header map is mutable but any changes must be made before writing to the output stream since the headers will be flushed prior to writing the message body.

Specified by:

writeTo in interface MessageBodyWriter<Object>

Parameters:

t - the instance to write.

type - the class of instance that is to be written.

genericType - the type of instance to be written. GenericEntity provides a way to specify this information at runtime.

annotations - an array of the annotations attached to the message entity instance.

mediaType - the media type of the HTTP entity.

httpHeaders - a mutable map of the HTTP message headers.

entityStream - the OutputStream for the HTTP entity. The implementation should not close the output stream.

Throws:

IOException - if an IO error arises.

WebApplicationException - if a specific HTTP error response needs to be produced. Only effective if thrown prior to the message being committed.
