abstract superclass for composite (multi-block or AMR) datasets
vtkCompositeDataSet is an abstract class that represents a collection of datasets (including other composite datasets). It provides an interface to access the datasets through iterators. vtkCompositeDataSet provides methods that are used by subclasses to store the datasets. vtkCompositeDataSet provides the datastructure for a full tree representation. Subclasses provide the semantics for it and control how this tree is built.

Copies the tree structure from the input.
All pointers to non-composite data objects are initialized to nullptr. This also shallow copies the meta data associated with all the nodes.
Reimplemented in vtkDataObjectTree, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.
|
pure virtual |
Sets the data set at the location pointed by the iterator.
The iterator does not need to be iterating over this dataset itself. It can be any composite dataset with similar structure (achieved by using CopyStructure).
Implemented in vtkDataObjectTree, and vtkUniformGridAMR.

Returns the dataset located at the position pointed by the flatIndex.
If no dataset has the same flat index, nullptr is returned.
It should be noted that this function should be used ONLY when you already know the flat index. It should NOT be used when you are iterating over the composite dataset (in that case, prefer the vtkCompositeDataIterator).
Reimplemented in vtkDataObjectTree, and vtkUniformGridAMR.

Return the geometric bounding box in the form (xmin,xmax, ymin,ymax, zmin,zmax).
Note that if the composite dataset contains abstract types (i.e., non vtkDataSet types) such as tables these will be ignored by the method. In cases where no vtkDataSet is contained in the composite dataset then the returned bounds will be undefined.

static |
Extract datasets from the given data object.
This method returns a vector of DataSetT* from the dobj
. If dobj is a DataSetT, the returned vector will have just 1 DataSetT. If dobj is a vtkCompositeDataSet, then we iterate over it and add all non-null leaf nodes to the returned vector.
If preserveNull
is true (defaults to false), then nullptr
place holders are added as placeholders when leaf node dataset type does not match the requested or is nullptr to begin with.

Returns true for POINT or CELL, false otherwise.
