public class CheckedInputStream
extends FilterInputStream
An input stream that also maintains a checksum of the data being read. The checksum can then be used to verify the integrity of the input data.

Checksum

Constructor Index

 o CheckedInputStream(InputStream, Checksum)
Creates an input stream using the specified Checksum.

Method Index

 o getChecksum()
Returns the Checksum for this input stream.
 o read()
Reads a byte.
 o read(byte[], int, int)
Reads into an array of bytes.
 o skip(long)
Skips specified number of bytes of input.

Constructors

 o CheckedInputStream
 public CheckedInputStream(InputStream in,
                           Checksum cksum)
Creates an input stream using the specified Checksum.

Parameters:
in - the input stream
cksum - the Checksum

Methods

 o read
 public int read() throws IOException
Reads a byte. Will block if no input is available.

Returns:
the byte read, or -1 if the end of the stream is reached.
Throws: IOException
if an I/O error has occurred
Overrides:
read in class FilterInputStream
 o read
 public int read(byte buf[],
                 int off,
                 int len) throws IOException
Reads into an array of bytes. Will block until some input is available.

Parameters:
buf - the buffer into which the data is read
off - the start offset of the data
len - the maximum number of bytes read
Returns:
the actual number of bytes read, or -1 if the end of the stream is reached.
Throws: IOException
if an I/O error has occurred
Overrides:
read in class FilterInputStream
 o skip
 public long skip(long n) throws IOException
Skips specified number of bytes of input.

Parameters:
n - the number of bytes to skip
Returns:
the actual number of bytes skipped
Throws: IOException
if an I/O error has occurred
Overrides:
skip in class FilterInputStream
 o getChecksum
 public Checksum getChecksum()
Returns the Checksum for this input stream.
