static CNKConverter* getDefaultConverter();

These methods support conversions between string and double or

time/date values. Such conversions depend upon a formatting string

that indicates things like whether

01/10/2002 represents January 10,

2002

or October 1, 2002.

Code using a pipeline can create a class extending

CNKConverter that

provides this support. Programmers creating Spotfire Miner nodes

will use the methods such as

convertStringToDouble(), and will not

use a

CNKConverter directly.

CNKObj::

static void copyPlainToUTFString(

const char* inputPlainString,

char* outputUTFString, int maxOutputBytes);

static void copyUTFToPlainString(

const char* inputUTFString,

char* outputPlainString, int maxOutputBytes);

static void copyWideCharToUTFString(

const wchar_t* inputWideCharString,

char* outputUTFString, int maxOutputBytes);

static void copyUTFToWideCharString(

const char* inputUTFString,

wchar_t* outputWideCharString, int maxOutputChars);

String values are typically stored as UTF-8 char arrays using the same

conventions as the Java Native Interface (JNI). This is a format that

uses one, two, or three bytes as needed to represent multibyte

characters in a char array.

Other common standards for representing characters in a char array

are to use a single byte per character or two bytes for every character.

These methods support conversions between a UTF-8 representation,

a single-byte representation (plain string), and a two-byte

representation (wide char string).

CNKObj::

virtual void setProperty(CNKPropertyInfo* propInfo);

virtual void getProperty(CNKPropertyInfo* propInfo);

These methods are defined in all of the CNK object classes, to

support the Java-to-C++ communication facility.
