These methods set/get the total number of rows to be written by this
proc, before the proc sends an
EOF to the output buf, and specifies that
it is done.
CNKProcNullReader::
void setAccessBuf(int val);
int getAccessBuf();
These methods access a flag that determines whether the proc
actually writes values to its output buf. By setting this to false (zero),
one can measure the minimum time for the pipeline to run, without
any data being transferred. In this case, the values read from the
output buf would be undefined.
CNKProcNullWriter : Null Writer Proc
The null writer proc is mainly used for testing the TIBCO Spotfire
Pipeline. It has one input buf, and no outputs. It simply consumes all
of its input rows.
CNKProcNullWriter::
CNKProcNullWriter();
virtual ~CNKProcNullWriter();
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.
CNKProcNullWriter::
void setAccessBuf(int val);
int getAccessBuf();
These methods access a flag that determines whether the proc
actually reads values from its input buf. By setting this to false (zero),
one can measure the minimum time for the pipeline to run, without
any data being transferred.
