/**
 * @class   vtkPartitionedDataSetCollection
 * @brief   Composite dataset that groups datasets as a collection.
 *
 * vtkPartitionedDataSetCollection is a vtkCompositeDataSet that stores
 * a collection of vtkPartitionedDataSets. These items can represent
 * different concepts depending on the context. For example, they can
 * represent region of different materials in a simulation or parts in
 * an assembly. It is not requires that items have anything in common.
 * For example, they can have completely different point or cell arrays.
