#include <vtkExtractBlock.h>
Detailed Description
extracts blocks from a multiblock dataset.
vtkExtractBlock is a filter that extracts blocks from a multiblock dataset. Each node in the multi-block tree is identified by an index. The index can be obtained by performing a preorder traversal of the tree (including empty nodes). eg. A(B (D, E), C(F, G)). Inorder traversal yields: A, B, D, E, C, F, G Index of A is 0, while index of C is 4.

| static vtkExtractBlock* vtkExtractBlock::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkMultiBlockDataSetAlgorithm.
| static int vtkExtractBlock::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkMultiBlockDataSetAlgorithm.
| virtual int vtkExtractBlock::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

| void vtkExtractBlock::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
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 vtkMultiBlockDataSetAlgorithm.
| void vtkExtractBlock::AddIndex | ( | unsigned int | index | ) |
Select the block indices to extract. Each node in the multi-block tree is identified by an index. The index can be obtained by performing a preorder traversal of the tree (including empty nodes). eg. A(B (D, E), C(F, G)). Inorder traversal yields: A, B, D, E, C, F, G Index of A is 0, while index of C is 4.
| void vtkExtractBlock::RemoveIndex | ( | unsigned int | index | ) |
Select the block indices to extract. Each node in the multi-block tree is identified by an index. The index can be obtained by performing a preorder traversal of the tree (including empty nodes). eg. A(B (D, E), C(F, G)). Inorder traversal yields: A, B, D, E, C, F, G Index of A is 0, while index of C is 4.
| void vtkExtractBlock::RemoveAllIndices | ( | ) |
Select the block indices to extract. Each node in the multi-block tree is identified by an index. The index can be obtained by performing a preorder traversal of the tree (including empty nodes). eg. A(B (D, E), C(F, G)). Inorder traversal yields: A, B, D, E, C, F, G Index of A is 0, while index of C is 4.
| virtual void vtkExtractBlock::SetPruneOutput | ( | int | ) | [virtual] |
When set, the output mutliblock dataset will be pruned to remove empty nodes. On by default.
| virtual int vtkExtractBlock::GetPruneOutput | ( | ) | [virtual] |
When set, the output mutliblock dataset will be pruned to remove empty nodes. On by default.
| virtual void vtkExtractBlock::PruneOutputOn | ( | ) | [virtual] |
When set, the output mutliblock dataset will be pruned to remove empty nodes. On by default.
| virtual void vtkExtractBlock::PruneOutputOff | ( | ) | [virtual] |
When set, the output mutliblock dataset will be pruned to remove empty nodes. On by default.
| virtual void vtkExtractBlock::SetMaintainStructure | ( | int | ) | [virtual] |
This is used only when PruneOutput is ON. By default, when pruning the output i.e. remove empty blocks, if node has only 1 non-null child block, then that node is removed. To preserve these parent nodes, set this flag to true. Off by default.
| virtual int vtkExtractBlock::GetMaintainStructure | ( | ) | [virtual] |
This is used only when PruneOutput is ON. By default, when pruning the output i.e. remove empty blocks, if node has only 1 non-null child block, then that node is removed. To preserve these parent nodes, set this flag to true. Off by default.
| virtual void vtkExtractBlock::MaintainStructureOn | ( | ) | [virtual] |
This is used only when PruneOutput is ON. By default, when pruning the output i.e. remove empty blocks, if node has only 1 non-null child block, then that node is removed. To preserve these parent nodes, set this flag to true. Off by default.
