Member Function Documentation

Final()

char * XrdCksCalccrc32C::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.

Definition at line 38 of file XrdCksCalccrc32C.cc.

{
    TheResult = C32CResult;
#ifndef Xrd_Big_Endian
    TheResult = htonl(TheResult);
#endif
    return (char *)&TheResult;
}

Init()

void XrdCksCalccrc32C::Init ( )

virtual

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

Implements XrdCksCalc.

Definition at line 33 of file XrdCksCalccrc32C.cc.

{
    C32CResult = C32C_XINIT;
}

Here is the caller graph for this function:

New()

XrdCksCalc * XrdCksCalccrc32C::New ( )

virtual

Get a new instance of the underlying checksum calculation object.

Returns

the checksum calculation object.

Implements XrdCksCalc.

Definition at line 31 of file XrdCksCalccrc32C.cc.

{ return (XrdCksCalc *)new XrdCksCalccrc32C; }

References XrdCksCalccrc32C().

Here is the call graph for this function:

Type()

const char * XrdCksCalccrc32C::Type ( int &  csSize )

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.

Definition at line 25 of file XrdCksCalccrc32C.cc.

{
    csSz = sizeof(TheResult);
    return "crc32c";
}

Update()

void XrdCksCalccrc32C::Update ( const char *  Buff, int  BLen  )

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.

Definition at line 20 of file XrdCksCalccrc32C.cc.

    C32CResult = (unsigned int)XrdOucCRC::Calc32C(Buff, BLen, C32CResult);
