superclass for composite data iterators
abstract superclass for composite (multi-block or AMR) datasets
~vtkCompositeDataSet() override
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).
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.
virtual void CopyStructure(vtkCompositeDataSet *input)
Copies the tree structure from the input.
void DeepCopy(vtkDataObject *src) override
Shallow and Deep copy.
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 positiong pointed by the iterator.
virtual void RecursiveShallowCopy(vtkDataObject *src)=0
For historical reasons, vtkCompositeDataSet::ShallowCopy simply pass pointers to the leaf non-composi...
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 ShallowCopy(vtkDataObject *src) override
Shallow and Deep copy.
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.
