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)
Creates an output stream with the specified Checksum.
Parameters: out - the output stream cksum - the checksum

public void write(int b) throws IOException
Writes a byte. Will block until the byte is actually written.
