Examples of java.io.ObjectOutputStream.reset()

java.io.ObjectOutputStream.reset()
Reset the receiver. A marker is written to the stream, so that deserialization will also perform a rest at the same point. Objects previously written are no longer remembered, so they will be written again (instead of a cyclical reference) if found in the object graph. @throws IOException If any IO problem occurred when trying to reset the receiver

        try {

                oos.reset();
            } finally {
                oos.close();

                    // The ObjectOutputStream will cache instances and if all you do is change a
                    // field or two in the object, it won't be detected and the stale object will be
                    // sent.  So you have to reset() the stream, (or use a new object, or use
                    // clone() here also if you want, but this is simplest and safest since we have
                    // no control over what the external pinger gives us.
