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

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
