getSize

public long getSize(T 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<T>

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.
