Member Function Documentation

float * FlowDataSet::getAddDataPointer (  int    dataindex, int    x, int    y, int    z = 0 )  [protected]

Accesses the original additional data. Parameters: dataindex  which additional data shall be accessed x  x location of data to be accessed y  y location of data to be accessed z  z location of data to be accessed (optional) Returns: pointer to according data if dataindex smaller than aCount and x,y,z in range, NULL otherwise

FlowData * FlowDataSet::getFlowDataPointer (  int    x, int    y, int    z = 0 )  [protected]

Accesses the original flow data. Parameters: x  x location of data to be accessed y  y location of data to be accessed z  z location of data to be accessed (optional) Returns: pointer to according flow data if x,y,z in range, NULL otherwise

GridData * FlowDataSet::getGridDataPointer (  int    x, int    y, int    z = 0 )  [protected]

Accesses the original grid data. Parameters: x  x location of data to be accessed y  y location of data to be accessed z  z location of data to be accessed (optional) Returns: pointer to according grid data if x,y,z in range, NULL otherwise

int FlowDataSet::loadDataset (  CString    geomPathName, CString    dataPathName )

Loads a dataset. Parameters: geomPathName  path of the geometry (*.gri) file dataPathName  path of the data (*.dat) file Returns: Returns 0 if the files could be loaded, -1 otherwise
