/**

|
* @class vtkMultiBlockDataSet
|
|
* @brief Composite dataset that organizes datasets into
|
|
* blocks.
|
|
*
|
|
* vtkMultiBlockDataSet is a vtkCompositeDataSet that stores
|
|
* a hierarchy of datasets. The dataset collection consists of
|
|
* multiple blocks. Each block can itself be a vtkMultiBlockDataSet, thus
|
|
* providing for a full tree structure.
|
|
* Sub-blocks are usually used to distribute blocks across processors.
|
|
* For example, a 1 block dataset can be distributed as following:
|
|
* @verbatim
|
|
* proc 0:
|
|
* Block 0:
|
|
* * ds 0
|
|
* * (null)
|
|
*
|
|
* proc 1:
|
|
* Block 0:
|
|
* * (null)
|
|
* * ds 1
|
|
* @endverbatim
