static int isLevelNumNA(long val);

static const char* getStringNA();

static int isStringNA(const char* val);

static CNKTimeDate getTimeDateNA();

static int isTimeDateNA(CNKTimeDate val);

These are useful utility methods for accessing the NaN value for

various buffer types, used in Spotfire Miner and Spotfire S+ for

representing

NA values. getDoubleNaN() returns the double NaN value.

isDoubleNaN(val) returns true (non-zero) if the argument is an NaN

value, false otherwise. The other methods provide this functionality

for other column types.

CNKObj::

static double convertLevelNumToDouble(long val);

static long convertDoubleToLevelNum(double val);

static const char* convertLevelNumToString(long val);

static long convertStringToLevelNum(const char* val);

static CNKTimeDate convertLevelNumToTimeDate(long val);

static long convertTimeDateToLevelNum(CNKTimeDate val);

static CNKTimeDate convertDoubleToTimeDate(double val);

static double convertTimeDateToDouble(CNKTimeDate val);

These methods provide support for conversions between data types.

They support any conversions that do not vary based on a specified

format string.

The

convertDoubleToTimeDate() and convertTimeDateToDouble()

methods convert between a double giving the number of days since

January 1, 1970 and a timeDate value. Hours, minutes, and seconds

are the fractional part of the double.

CNKObj::

double convertStringToDouble(const char* val);

const char* convertDoubleToString(double val);

CNKTimeDate convertStringToTimeDate(const char* val);

const char* convertTimeDateToString(CNKTimeDate val);

void setConverter(CNKConverter* val);

CNKConverter* getConverter();

static void setDefaultConverter(CNKConverter* val);
