Detailed Description

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:

* proc 0:
* Block 0:
*   * ds 0
*   * (null)
*
* proc 1:
* Block 0:
*   * (null)
*   * ds 1
*

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkDataObjectTree.

◆ GetDataObjectType()

int vtkMultiBlockDataSet::GetDataObjectType ( )

inlineoverridevirtual

Return class name of data type (see vtkType.h for definitions).

Reimplemented from vtkDataObjectTree.

Definition at line 165 of file vtkMultiBlockDataSet.h.

◆ SetNumberOfBlocks()

void vtkMultiBlockDataSet::SetNumberOfBlocks ( unsigned int numBlocks )

Set the number of blocks.

This will cause allocation if the new number of blocks is greater than the current size. All new blocks are initialized to null.

unsigned int vtkMultiBlockDataSet::GetNumberOfBlocks ( )

Returns the number of blocks.

◆ GetBlock()

vtkDataObject * vtkMultiBlockDataSet::GetBlock ( unsigned int blockno )

Returns the block at the given index.

It is recommended that one uses the iterators to iterate over composite datasets rather than using this API.

◆ SetBlock()

void vtkMultiBlockDataSet::SetBlock	(	unsigned int	blockno,
		vtkDataObject *	block
	)

Sets the data object as the given block.

The total number of blocks will be resized to fit the requested block no.

Remarks: while most vtkDataObject subclasses, including vtkMultiBlockDataSet as acceptable as a block, vtkPartitionedDataSet, vtkPartitionedDataSetCollection, and vtkUniformGridAMR are not valid.

void vtkMultiBlockDataSet::RemoveBlock ( unsigned int blockno )

Remove the given block from the dataset.

◆ HasMetaData() [1/2]

int vtkMultiBlockDataSet::HasMetaData ( unsigned int blockno )
