void XrdCksCalcmd5::byteReverse	(	unsigned char *	buf,
		unsigned	longs
	)			[private]

char* XrdCksCalcmd5::Current

(

)

[inline, virtual]

Get the current binary checksum value (defaults to final). However, the final checksum result is not affected.

Returns:

the checksum value in binary format. The pointer to the value becomes invalid once the associated object is deleted.

Reimplemented from XrdCksCalc.

References Final(), and myContext.

char* XrdCksCalcmd5::Final

(

)

[virtual]

Get the actual checksum in binary format.

Returns:

the checksum value in binary format. The pointer to the value becomes invalid once the associated object is deleted.

Implements XrdCksCalc.

Referenced by Current().

void XrdCksCalcmd5::Init

(

)

[virtual]

Initializes data structures (must be called by constructor). This is always called to reuse the object for a new checksum.

Implements XrdCksCalc.

Referenced by XrdCksCalcmd5().

void XrdCksCalcmd5::MD5Transform	(	unsigned int	buf[4],
		unsigned int const	in[16]
	)			[private]

void XrdCksCalcmd5::MD5Update	(	unsigned char const *	buf,
		unsigned int	len
	)			[private]

Referenced by Update().

XrdCksCalc* XrdCksCalcmd5::New

(

)

[inline, virtual]

Get a new instance of the underlying checksum calculation object.

Returns:

the checksum calculation object.

Implements XrdCksCalc.

const char* XrdCksCalcmd5::Type

(

int &

csSize

)

[inline, virtual]

Get the checksum object algorithm name and the number bytes (i.e. size) required for the checksum value.

Parameters:

csSize

-> Parameter to hold the size of the checksum value.

Returns:

the checksum algorithm's name. The name persists event after the checksum object is deleted.

Implements XrdCksCalc.

References myDigest.

void XrdCksCalcmd5::Update	(	const char *	Buff,
		int	BLen
	)			[inline, virtual]

Compute a running checksum. This method may be called repeatedly for data segments; with Final() returning the full checksum.

Parameters:

	Buff	-> Data to be checksummed.
	BLen	-> Length of the data in Buff.

Implements XrdCksCalc.
