With setConvertFactor, if the column is actually a double column,

the argument is registered as a factor level for the column (by calling

CNKBuf::mapLevelToDouble), and the value associated with that factor

level is assigned. The order of the values is not particularly

meaningful.

CNKBufWriter::

virtual void setDoubleArray(long firstRowNum,

int columnNum, long numRows, double* ptr);

This method copies multiple values from the array *ptr into a

column of values stored in the

CNKBuf. columnNum identifies the

column in

CNKBuf of the data being copied, from 0 to

CNKBuf::getNumcolumns()-1. firstRowNum is the row number of the

first row to copy in the currently-accessible chunk of data rows: it

should be zero or greater.

numRows is the number of values to copy.

firstRowNum + numRows should be less than getRowsReady().

CNKBufWriter::

virtual void releaseRows(long numRows);

After writing up to getRowsReady() data rows (using the methods

such as

setDouble, etc.), releaseRows(numRows) is called to release

the first

numRows rows of the available rows, so they can be read by

other

CNKProc objects. A CNKProc may release all of the

getRowsReady() data rows at once, or fewer rows.

numRows is less than zero, or greater than getRowsReady(), then an

error string is set for the

CNKProc using this CNKBufWriter. In

addition, if this is called after the

EOF flag has been set with setEOF, an

error string is set for the

CNKProc.

CNKBufWriter::

virtual void setEOF();

setEOF() should be called after a CNKProc has written all of the data to

the

CNKBuf that it ever will, and called releaseRows to release these

rows. This sets a flag in the

CNKBuf, so the CNKProc objects reading

this

CNKBuf will know not to wait for any more data. After this is

called,

releaseRows should never be called again: if it is, an error

string is set for the

CNKProc.
