Constructs a new CheckedInputStream on InputStream is. The checksum will be calculated using the algorithm implemented by csum.

Warning: passing a null source creates an invalid CheckedInputStream. All operations on such a stream will fail.

Parameters:

is - the input stream to calculate checksum from.
