| ObjectOutputStream |
An ObjectOutputStream can be used to save Java objects into a stream where
the objects can be loaded later with an ObjectInputStream. |
|
Class Overview
Streams to be used with serialization to write objects must implement this
interface. ObjectOutputStream is one example.

()
Close this ObjectOutput. Concrete implementations of this class should
free any resources during close.
Throws
| IOException
| If an error occurs attempting to close this ObjectOutput.

void
flush
()
Flush this ObjectOutput. Concrete implementations of this class should
ensure any pending writes are written out when this method is envoked.
Throws
