Member Function Documentation

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.

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().

XrdCksCalc* XrdCksCalcadler32::New ( )

inlinevirtual

Get a new instance of the underlying checksum calculation object.

Returns:

the checksum calculation object.

Implements XrdCksCalc.

References XrdCksCalcadler32().

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.

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.
