 java.io.OutputStream
java.io.FilterOutputStream
java.util.zip.CheckedOutputStream
| CheckedOutputStream | | public class CheckedOutputStream extends java.io.FilterOutputStream (Code) | | The CheckedOutputStream class is used to maintain a running Checksum of all
data written to a stream.
|
| Method Summary | |
| public Checksum | getChecksum()
Returns the Checksum calculated on the stream thus far. | | public void | write(int val)
Writes byte value val to the underlying stream. | | public void | write(byte[] buf, int off, int nbytes)
Writes nbytes of data from buf starting at offset off to the underlying
stream. |
| CheckedOutputStream | | public CheckedOutputStream(OutputStream os, Checksum cs)(Code) | | Constructs a new CheckedOutputStream on OutputStream os. The Checksum
will be calculated using the algorithm implemented by csum.
Parameters:
os - OutputStream to calculate checksum from
Parameters:
cs - Type of Checksum to calculate |
| getChecksum | | public Checksum getChecksum()(Code) | | Returns the Checksum calculated on the stream thus far.
A java.util.zip.Checksum |
| write | | public void write(int val) throws IOException(Code) | | Writes byte value val to the underlying stream. The Checksum is updated
with val.
Parameters:
val - Value of the byte to write out
throws:
IOException - if an IO error has occured |
| write | | public void write(byte[] buf, int off, int nbytes) throws IOException(Code) | | Writes nbytes of data from buf starting at offset off to the underlying
stream. The Checksum is updated with the bytes written.
Parameters:
buf - data to write out
Parameters:
off - the start offset of the data
Parameters:
nbytes - number of bytes to write out
throws:
IOException - if an IO error has occured |
