All Implemented Interfaces:

java.io.Closeable, java.io.DataOutput, java.io.Flushable, java.io.ObjectOutput, java.io.ObjectStreamConstants

public class NbObjectOutputStream
extends java.io.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(java.io.OutputStream os)
                     throws java.io.IOException

Create a new object output.

Parameters:

os - the underlying output stream

Throws:

java.io.IOException - for the usual reasons

Method Detail

replaceObject

public java.lang.Object replaceObject(java.lang.Object obj)
                               throws java.io.IOException

Overrides:

replaceObject in class java.io.ObjectOutputStream

Throws:

java.io.IOException

writeSafely

public static void writeSafely(java.io.ObjectOutput oo,
                               java.lang.Object obj)
                        throws java.io.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

java.io.IOException - if something more serious fails

annotateClass

protected void annotateClass(java.lang.Class cl)
                      throws java.io.IOException

Overrides:

annotateClass in class java.io.ObjectOutputStream

Throws:

java.io.IOException
