Member Function Documentation

Final()

char * XrdCksCalcadler32::Final ( )

inlinevirtual

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.

References AdlerValue, unSum1, and unSum2.

Init()

void XrdCksCalcadler32::Init ( )

inlinevirtual

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

Implements XrdCksCalc.

References AdlerStart, unSum1, and unSum2.

Referenced by XrdCksCalcadler32().

New()

XrdCksCalc * XrdCksCalcadler32::New ( )

inlinevirtual

Get a new instance of the underlying checksum calculation object.

Returns

the checksum calculation object.

Implements XrdCksCalc.

References XrdCksCalcadler32().

Type()

const char * XrdCksCalcadler32::Type ( int &  csSize )

inlinevirtual

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 AdlerValue.

Update()

void XrdCksCalcadler32::Update ( const char *  Buff, int  BLen  )

inlinevirtual

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.
