public class WrapperObjectOutputStream
extends WrapperDataOutputStream
implements ObjectOutput

This is an imitation ObjectOutputStream class that provides the ObjectOutput interface by delegating to an object that implements the ObjectOutput interface. Primarily, this is intended as a base class for building specific-purpose ObjectOutput wrappers.

Constructor Details

WrapperObjectOutputStream

public WrapperObjectOutputStream(ObjectOutput out)

Construct a WrapperObjectOutputStream that will output to the specified object implementing the ObjectOutput interface.

Parameters:

out - an object implementing ObjectOutput to write to

Method Details

getObjectOutput

public ObjectOutput getObjectOutput()

Obtain the underlying object providing the ObjectOutput interface that this object is delegating to.

Returns:

the underlying ObjectOutput

getBytesWritten

public long getBytesWritten()

Return the total number of bytes written to the wrapped DataOutput object.

This method is unsupported.

Overrides:

getBytesWritten in class WrapperDataOutputStream

Returns:

the total number of bytes written

Throws:

UnsupportedOperationException - always

writeObject

public void writeObject(Object o)
                 throws IOException

Writes the Object o so that the corresponding ObjectInput.readObject() method can reconstitute an Object from the written data.

Specified by:

writeObject in interface ObjectOutput

Parameters:

o - the Object to write

Throws:

IOException - if an I/O error occurs
