setCrossIndex sets the crosstab level for the crosstab column

specified by

crossNum. The level for this column is set to levelNum,

which is interpreted the same as in

getColumnLevelName above. Note

that the column is specified by the crosstab column number (from

getCrossSize()-1), rather than the input column number.

Therefore,

levelNum should range from 0 to

getColumnNumLevels(getCrossColumn(crossNum)).

CNKProcCount::

int getNumCountBlocks();

CNKProcCount

dynamically allocates "count blocks" to store the counts

for new factor levels. The number of these blocks can grow greatly,

especially when accumulating crosstabs. This method returns the

number of count blocks in use for a given count proc.

Utility Procs When developing a proc, it is sometimes useful to have simple

components available to provide data, accept data, and print data

values. The

CNKProcNullReader, CNKProcNullWriter,

CNKProcPrintf, and CNKProcRandomReader procs are utilities for use

in debugging new procs.

CNKProcNullReader : Null reader proc

The null reader proc is mainly used for testing the TIBCO Spotfire

Pipeline. It has no inputs, and one output buf. It writes 1,2,3,... on its

first column output, 2,3,4,... on the next, etc.

CNKProcNullReader::

CNKProcNullReader();

virtual ~CNKProcNullReader();

virtual void init();

virtual void execute();

These are the constructor, destructor, and init() methods. The

execute() method is run when this CNKProc is executed within a

pipeline.

CNKProcNullReader::

void setTotalRows(INT64 rows);

INT64 getTotalRows();

1 2 ... 88 89 90 91 92 93 94 95 96 97 98
