Detailed Description

Clas that can be used to compute an Adler-32 Checksum for a data stream.

The Alder-32 checksum trades reliability for speed over the CRC-32 algorithm.

Since:

1.0

Member Function Documentation

virtual long long decaf::util::zip::Adler32::getValue

(

)

const [virtual]

Returns:

the current checksum value.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::Adler32::reset

(

)

[virtual]

Reset the checksum to its initial value.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::Adler32::update	(	const unsigned char *	buffer,
		int	size,
		int	offset,
		int	length
	)		[virtual]

Updates the current checksum with the specified array of bytes.

Parameters:

buffer	The buffer to read the updated bytes from.
size	The size of the passed buffer.
offset	The position in the buffer to start reading.
length	The amount of data to read from the byte buffer.

Exceptions:

NullPointerException	if the passed buffer is NULL.
IndexOutOfBoundsException	if offset + length > size of the buffer.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::Adler32::update	(	const std::vector< unsigned char > &	buffer,
		int	offset,
		int	length
	)		[virtual]

Updates the current checksum with the specified array of bytes.

Parameters:

buffer	The buffer to read the updated bytes from.
offset	The position in the buffer to start reading.
length	The amount of data to read from the byte buffer.

Exceptions:

IndexOutOfBoundsException

if offset + length > size of the buffer.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::Adler32::update

(

const std::vector< unsigned char > &

buffer

)

[virtual]

Updates the current checksum with the specified vector of bytes.

Parameters:

buffer

The buffer to read the updated bytes from.

Implements decaf::util::zip::Checksum.

virtual void decaf::util::zip::Adler32::update

(

int

byte

)

[virtual]

Updates the current checksum with the specified byte value.

Parameters:

byte	The byte value to update the current Checksum with (0..255).
