java.lang.Object
  extended by java.io.OutputStream

All Implemented Interfaces:
Closeable, DataOutput, Flushable, ObjectOutput, ObjectStreamConstants

public class NbObjectOutputStream
extends ObjectOutputStream

Object output stream that could in the future be smart about saving certain objects. Also static methods to safely write an object that could cause problems during later deserialization.

Constructor Detail

NbObjectOutputStream

public NbObjectOutputStream(OutputStream os)
                     throws IOException
Create a new object output.

Parameters:
os - the underlying output stream
Throws:
IOException - for the usual reasons
Method Detail

replaceObject

public Object replaceObject(Object obj)
                     throws IOException
Overrides:
replaceObject in class ObjectOutputStream
Throws:
IOException

writeSafely

public static void writeSafely(ObjectOutput oo,
                               Object obj)
                        throws IOException
Writes an object safely to the object output. Can be read by NbObjectInputStream.readSafely(java.io.ObjectInput).

Parameters:
oo - object output to write to
obj - the object to write
Throws:
SafeException - if the object simply fails to be serialized
IOException - if something more serious fails

annotateClass

protected void annotateClass(Class cl)
                      throws IOException
Overrides:
annotateClass in class ObjectOutputStream
Throws:
IOException
