superclass for composite data iterators
abstract superclass for composite (multi-block or AMR) datasets
~vtkCompositeDataSet() override
virtual vtkDataObject * GetDataSet(unsigned int flatIndex)
Returns the dataset located at the position pointed by the flatIndex.
virtual vtkIdType GetNumberOfCells()
Returns the total number of cells of all blocks.
virtual void SetDataSet(vtkCompositeDataIterator *iter, vtkDataObject *dataObj)=0
Sets the data set at the location pointed by the iterator.
void GetBounds(double bounds[6])
Return the geometric bounding box in the form (xmin,xmax, ymin,ymax, zmin,zmax).
virtual void CompositeShallowCopy(vtkCompositeDataSet *src)
The goal of the method is to copy the data up to the dataset pointers only.
static vtkCompositeDataSet * GetData(vtkInformationVector *v, int i=0)
Retrieve an instance of this class from an information object.
vtkIdType GetNumberOfElements(int type) override
Get the number of elements for a specific attribute type (POINT, CELL, etc.).
virtual vtkIdType GetNumberOfPoints()
Returns the total number of points of all blocks.
static vtkCompositeDataSet * GetData(vtkInformation *info)
Retrieve an instance of this class from an information object.
bool SupportsGhostArray(int type) override
Returns true for POINT or CELL, false otherwise.
virtual void CopyStructure(vtkCompositeDataSet *input)
Copies the tree structure from the input.
int GetDataObjectType() override
Return class name of data type (see vtkType.h for definitions).
virtual vtkDataObject * GetDataSet(vtkCompositeDataIterator *iter)=0
Returns the dataset located at the position pointed by the iterator.
void Initialize() override
Restore data object to initial state,.
unsigned long GetActualMemorySize() override
Return the actual size of the data in kibibytes (1024 bytes).
static std::vector< DataSetT * > GetDataSets(vtkDataObject *dobj, bool preserveNull=false)
Extract datasets from the given data object.
static vtkInformationStringKey * NAME()
Key used to put node name in the meta-data associated with a node.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual vtkCompositeDataIterator * NewIterator()=0
Return a new iterator (the iterator has to be deleted by user).
static vtkInformationIntegerKey * CURRENT_PROCESS_CAN_LOAD_BLOCK()
Key used to indicate that the current process can load the data in the node.
