Method Details

start

public void start(ByteOutput newOutput)
           throws IOException

Description copied from interface: Marshaller

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

Description copied from interface: Marshaller

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

Description copied from interface: Marshaller

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

Description copied from interface: Marshaller

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

writeObject

public void writeObject(Object obj)
                 throws IOException

Specified by:

writeObject in interface ObjectOutput

Throws:

IOException

writeObjectUnshared

public void writeObjectUnshared(Object obj)
                         throws IOException

Description copied from interface: Marshaller

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

doWriteObject

private void doWriteObject(Object obj,
 boolean unshared)
                    throws IOException

Throws:

IOException

write

public void write(int v)
           throws IOException

Description copied from interface: ByteOutput

Writes to the output stream the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Specified by:

write in interface ByteOutput

Specified by:

write in interface DataOutput

Specified by:

write in interface ObjectOutput

Parameters:

v - the byte to write

Throws:

IOException - if an error occurs

write

public void write(byte[] b)
           throws IOException

Description copied from interface: ByteOutput

Write all the bytes from the given array to the stream.

Specified by:

write in interface ByteOutput

Specified by:

write in interface DataOutput

Specified by:

write in interface ObjectOutput

Parameters:

b - the byte array

Throws:

IOException - if an error occurs

write

public void write(byte[] bytes,
 int off,
 int len)
           throws IOException

Description copied from interface: ByteOutput

Write some of the bytes from the given array to the stream.

Specified by:

write in interface ByteOutput

Specified by:

write in interface DataOutput

Specified by:

write in interface ObjectOutput

Parameters:

bytes - the byte array

off - the index to start writing from

len - the number of bytes to write

Throws:

IOException - if an error occurs
