Parameters:

output - the object output to write to

object - the object reference to write

Throws:

java.io.IOException - if an I/O error occurs

doWriteObject

public abstract void doWriteObject(java.io.ObjectOutput output,
                                   T object)
                            throws java.io.IOException

                   throws java.io.IOException,
                          java.lang.ClassNotFoundException

Description copied from interface: Externalizer

Parameters:

input - the object input to read from

Returns:

the object instance

Throws:

java.io.IOException - if an I/O error occurs

java.lang.ClassNotFoundException - if a class could not be found
