Write an object to the underlying storage or stream as a new instance. The class that implements this interface defines how the object is written.

Specified by:

writeObjectUnshared in interface Marshaller

Parameters:

obj - the object to be written

Throws:

IOException - if an error occurs

start

public void start(ByteOutput newOutput)
           throws IOException

Begin marshalling to a stream.

Specified by:

start in interface Marshaller

Parameters:

newOutput - the new stream

Throws:

IOException - if an error occurs during setup, such as an error writing the header

clearInstanceCache

public void clearInstanceCache()
                        throws IOException

Discard the instance cache. May also discard the class cache in implementations that do not support separated class and instance caches.

Specified by:

clearInstanceCache in interface Marshaller

Throws:

IOException - if an error occurs

clearClassCache

public void clearClassCache()
                     throws IOException

Discard the class cache. Implicitly also discards the instance cache.

Specified by:

clearClassCache in interface Marshaller

Throws:

IOException - if an error occurs

finish

public void finish()
            throws IOException

Finish marshalling to a stream. Any transient class or instance cache is discarded. The stream is released. No further marshalling may be done until the Marshaller.start(ByteOutput) method is again invoked.

Specified by:

finish in interface Marshaller

Throws:

IOException - if an error occurs
