Constructor Detail

• CheckedInputStream

  public CheckedInputStream​(InputStream in,Checksum cksum)

  Creates an input stream using the specified Checksum.

  Parameters:

  in - the input stream

  cksum - the Checksum

Method Detail

• read

  public int read()         throwsIOException

  Reads a byte. Will block if no input is available.

  Overrides:

  read in class FilterInputStream

  Returns:

  the byte read, or -1 if the end of the stream is reached.

  Throws:

  IOException - if an I/O error has occurred

  See Also:

  FilterInputStream.in

• read

  public int read​(byte[] buf,                int off,                int len)         throwsIOException

  Reads into an array of bytes. Iflen is not zero, the method blocks until some input is available; otherwise, no bytes are read and0 is returned.

  Overrides:

  read in class FilterInputStream

  Parameters:

  buf - the buffer into which the data is read

  off - the start offset in the destination arrayb

  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:

  NullPointerException - Ifbuf isnull.

  IndexOutOfBoundsException - Ifoff is negative,len is negative, orlen is greater thanbuf.length - off

  IOException - if an I/O error has occurred

• skip

  public long skip​(long n)          throwsIOException

  Skips specified number of bytes of input.

  Overrides:

  skip in class FilterInputStream

  Parameters:

  n - the number of bytes to skip

  Returns:

  the actual number of bytes skipped

  Throws:

  IOException - if an I/O error has occurred

• getChecksum

  public Checksum getChecksum()

  Returns the Checksum for this input stream.

  Returns:

  the Checksum value
