Class CountingInputStream

Constructor Detail

• CountingInputStream

  public CountingInputStream(InputStream in)

  Constructs a new CountingInputStream.

  Parameters:

  in - the InputStream to delegate to

Method Detail

• skip

  public long skip(long length)
            throws IOException

  Skips the stream over the specified number of bytes, adding the skipped amount to the count.

  Overrides:

  skip in class  ProxyInputStream

  Parameters:

  length - the number of bytes to skip

  Returns:

  the actual number of bytes skipped

  Throws:

  IOException - if an I/O error occurs.

  See Also:

  InputStream.skip(long)

• afterRead

  protected void afterRead(int n)

  Adds the number of read bytes to the count.

  Overrides:

  afterRead in class  ProxyInputStream

  Parameters:

  n - number of bytes read, or -1 if no more bytes are available

  Since:

  2.0

• getCount

  public int getCount()

  The number of bytes that have passed through this stream.

  NOTE: From v1.3 this method throws an ArithmeticException if the count is greater than can be expressed by an int. See getByteCount() for a method using a long.

  Returns:

  the number of bytes accumulated

  Throws:

  ArithmeticException - if the byte count is too large

• resetCount

  public int resetCount()

  Set the byte count back to 0.

  NOTE: From v1.3 this method throws an ArithmeticException if the count is greater than can be expressed by an int. See resetByteCount() for a method using a long.

  Returns:

  the count previous to resetting

  Throws:

  ArithmeticException - if the byte count is too large

• getByteCount

  public long getByteCount()

  The number of bytes that have passed through this stream.

  NOTE: This method is an alternative for getCount() and was added because that method returns an integer which will result in incorrect count for files over 2GB.

  Returns:

  the number of bytes accumulated

  Since:

  1.3

• resetByteCount

  public long resetByteCount()

  Set the byte count back to 0.

  NOTE: This method is an alternative for resetCount() and was added because that method returns an integer which will result in incorrect count for files over 2GB.

  Returns:

  the count previous to resetting

  Since:
