  • writetop

    public abstract void write(ObjectOutput out) throws IOException
    Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced this PutField object.
    Parameters:
    @param out the stream to write the data and fields to
    Exceptions:
    @throws IOException if I/O errors occur while writing to the underlying stream
    @throws IllegalArgumentException if the specified stream is not the same stream that produced this PutField object
    Deprecated:
    @deprecated This method does not write the values contained by this PutField object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField data is by calling the java.io.ObjectOutputStream.writeFields() method.
