C++ (Cpp) ossHash Examples

Example #1

File: optAccessPlan.hpp Project: horizon3d/SequoiaDB

 static UINT32 hash ( const BSONObj &query, const BSONObj &orderBy,
                      const BSONObj &hint )
 {
    return ossHash ( query.objdata(), query.objsize() ) ^
           ossHash ( orderBy.objdata(), orderBy.objsize() ) ^
           ossHash ( hint.objdata(), hint.objsize() ) ;
 }

Example #2

File: ixmBucket.cpp Project: amaliujia/StoneDB

int ixmBucketManager::_processData(BSONObj &record,
                                   dmsRecordID &recordID,
                                   unsigned int &hashNum,
                                   ixmEleHash &eleHash,
                                   unsigned int &random)
{
   int rc = EDB_OK;
   BSONElement element = record.getField(IXM_KEY_FIELDNAME);
   // check if _id exists and correct
   if(element.eoo()||
       (element.type() != NumberInt && element.type() != String))
   {
      rc = EDB_INVALIDARG;
      PD_LOG(PDERROR, "record must be with _id");
      goto error;
   }
   // hash _id
   hashNum = ossHash(element.value(), element.valuesize());
   random = hashNum % IXM_HASH_MAP_SIZE;
   eleHash.data = element.rawdata();
   eleHash.recordID = recordID;
done:
   return rc;
error:
   goto done;
}

Example #3

File: ossUtil.c Project: 2015520/SequoiaDB

UINT32 ossHashFileName ( const CHAR *fileName )
{
   const CHAR *pathSep = OSS_FILE_SEP ;
   const CHAR *pFileName = ossStrrchr ( fileName, pathSep[0] ) ;
   if ( !pFileName )
      pFileName = fileName ;
   else
      pFileName++ ;
   return ossHash ( pFileName, (INT32)ossStrlen ( pFileName ) ) ;
}

Example #4

 void set( const bson::OID *oid,
           UINT32 sequence,
           UINT32 offset,
           UINT32 dataLen,
           const CHAR *data )

    _oid = oid ;
    _sequence = sequence ;
    _offset = offset ;
    _hash = ossHash( ( const BYTE * )_oid->getData(), 12,
                     ( const BYTE * )( &_sequence ),
                     sizeof( _sequence ) ) ;
    _dataLen = dataLen ;
    _data = data ;
