MessageBodyWriterwriteTo to ascertain the length in bytes of
the serialized form of t. A non-negative return value is
used in a HTTP Content-Length header.getSize in interface MessageBodyWriter<T>t - the instance to writetype - the class of object that is to be written.genericType - the type of object to be written, obtained either
by reflection of a resource method return type or by inspection
of the returned instance. GenericEntity
