XrdCksCalc () | |
Constructor. | |
virtual | ~XrdCksCalc () |
Destructor. |
XrdCksCalc::XrdCksCalc | ( | ) | [inline] |
Constructor.
virtual XrdCksCalc::~XrdCksCalc | ( | ) | [inline, virtual] |
Destructor.
virtual char* XrdCksCalc::Calc | ( | const char * | Buff, | |
int | BLen | |||
) | [inline, virtual] |
Calculate a one-time checksum. The obvious default implementation is provided and assumes that Init() may be called more than once.
Buff | -> Data to be checksummed. | |
BLen | -> Length of the data in Buff. |
virtual char* XrdCksCalc::Current | ( | ) | [inline, virtual] |
Get the current binary checksum value (defaults to final). However, the final checksum result is not affected.
virtual char* XrdCksCalc::Final | ( | ) | [pure virtual] |
Get the actual checksum in binary format.
virtual void XrdCksCalc::Init | ( | ) | [pure virtual] |
Initializes data structures (must be called by constructor). This is always called to reuse the object for a new checksum.
virtual XrdCksCalc* XrdCksCalc::New | ( | ) | [pure virtual] |
Get a new instance of the underlying checksum calculation object.
virtual void XrdCksCalc::Recycle | ( | ) | [inline, virtual] |
Recycle the checksum object as it is no longer needed. A default is given.
virtual const char* XrdCksCalc::Type | ( | int & | csSize | ) | [pure virtual] |
Get the checksum object algorithm name and the number bytes (i.e. size) required for the checksum value.
csSize | -> Parameter to hold the size of the checksum value. |
virtual void XrdCksCalc::Update | ( | const char * | Buff, | |
int | BLen | |||
) | [pure virtual] |
Compute a running checksum. This method may be called repeatedly for data segments; with Final() returning the full checksum.
Buff | -> Data to be checksummed. | |
BLen | -> Length of the data in Buff. |
