- All Implemented Interfaces: 
- Closeable, DataOutput, Flushable, ObjectOutput, ObjectStreamConstants
- public class SerialOutput 
- extends ObjectOutputStream
A specialized 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.

SerialOutput
public SerialOutput(OutputStream out,
                    ClassCatalog classCatalog)
             throws IOException
- Creates a serial output stream.
 
- Parameters:
- out- is the output stream to which the compact serialized objects
 will be written.
- classCatalog- is the catalog to which the class descriptions for
 the serialized objects will be written.
- Throws:
- IOException
 
writeClassDescriptor
protected void writeClassDescriptor(ObjectStreamClass classdesc)
                             throws IOException
- 
- Overrides:
- writeClassDescriptorin class- ObjectOutputStream
 
- 
- Throws:
- IOException
 
getStreamHeader
public static byte[] getStreamHeader()
- Returns the fixed stream header used for all serialized streams in
 PROTOCOL_VERSION_2 format.  To save space this header can be removed and
 serialized streams before storage and inserted before deserializing.
 SerialOutputalways uses PROTOCOL_VERSION_2 serialization format
 to guarantee that this header is fixed.SerialBindingremoves
 this header from serialized streams automatically.
 
- 
- Returns:
- the fixed stream header.
