public class CheckedOutputStream
extends FilterOutputStream

An output stream that also maintains a checksum of the data being written. The checksum can then be used to verify the integrity of the output data.

See Also:: Checksum

CheckedOutputStream(OutputStream, Checksum): Creates an output stream with the specified Checksum.

getChecksum(): Returns the Checksum for this output stream.
write(byte[], int, int): Writes an array of bytes.
write(int): Writes a byte.

 public CheckedOutputStream(OutputStream out,
                            Checksum cksum)

                   int off,
                   int len) throws IOException
