public class SerialOutput extends ObjectOutputStream
ObjectOutputStream
that stores class description
information in a ClassCatalog
. It is used by
SerialBinding
.
This class is used instead of an ObjectOutputStream, which it extends, to write a compact object stream. For writing objects to a database normally one of the serial binding classes is used. SerialOutput is used when an ObjectOutputStream is needed along with compact storage. A ClassCatalog must be supplied, however, to stored shared class descriptions.
The ClassCatalog is used to store class definitions rather than embedding these into the stream. Instead, a class format identifier is embedded into the stream. This identifier is then used by SerialInput to load the class format to deserialize the object.
