Method Detail

readFrom

public Object readFrom(Class<Object> type,
                       Type genericType,
                       Annotation[] annotations,
                       MediaType mediaType,
                       MultivaluedMap<String,String> httpHeaders,
                       InputStream entityStream)
                throws IOException,
                       WebApplicationException

Description copied from interface: MessageBodyReader

Read a type from the InputStream.

Specified by:

readFrom in interface MessageBodyReader<Object>

Overrides:

readFrom in class CollectionProvider

Parameters:

type - the type that is to be read from the entity stream.

genericType - the type of instance to be produced. E.g. if the message body is to be converted into a method parameter, this will be the formal type of the method parameter as returned by Method.getGenericParameterTypes.

annotations - an array of the annotations on the declaration of the artifact that will be initialized with the produced instance. E.g. if the message body is to be converted into a method parameter, this will be the annotations on that parameter returned by Method.getParameterAnnotations.

mediaType - the media type of the HTTP entity.

httpHeaders - the read-only HTTP headers associated with HTTP entity.

entityStream - the InputStream of the HTTP entity. The caller is responsible for ensuring that the input stream ends when the entity has been consumed. The implementation should not close the input stream.

Returns:

the type that was read from the 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 response being committed.

writeTo

public void writeTo(Object entry,
                    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>

Overrides:

writeTo in class CollectionProvider

Parameters:

entry - 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.
