Definition: vtkType.h:287
vtkIdType GetNumberOfColumnsForRequest(vtkIdType r)
Return the number of columns associated with request r.
int AddColumnPairToRequests(const char *cola, const char *colb)
This function does not use the buffer like other column selection methods.
int AddBufferToRequests()
Empty current buffer.
vtkIdType GetNumberOfRequests()
Return the number of currently-defined requests.
bool GetColumnForRequest(vtkIdType r, vtkIdType c, vtkStdString &columnName)
Provide the name of the c-th column of the r-th request in columnName.
std::set< std::set< vtkStdString > > Requests
void ResetRequests()
Empty current set of requests.
