Detailed Description

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.

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.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, vtkHierarchicalBoxDataSet, vtkMultiBlockDataSet, vtkMultiPieceDataSet, vtkNonOverlappingAMR, vtkOverlappingAMR, vtkPartitionedDataSet, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.

◆ PrintSelf()

void vtkCompositeDataSet::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkObject.

Reimplemented in vtkDataObjectTree, vtkHierarchicalBoxDataSet, vtkMultiBlockDataSet, vtkMultiPieceDataSet, vtkNonOverlappingAMR, vtkOverlappingAMR, vtkPartitionedDataSet, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.

◆ NewIterator()

virtual vtkCompositeDataIterator * vtkCompositeDataSet::NewIterator ( )

pure virtual

Return a new iterator (the iterator has to be deleted by user).

Implemented in vtkDataObjectTree, vtkHierarchicalBoxDataSet, vtkOverlappingAMR, and vtkUniformGridAMR.

◆ GetDataObjectType()

int vtkCompositeDataSet::GetDataObjectType ( )

inlineoverridevirtual

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

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, vtkHierarchicalBoxDataSet, vtkMultiBlockDataSet, vtkMultiPieceDataSet, vtkNonOverlappingAMR, vtkOverlappingAMR, vtkPartitionedDataSet, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.

Definition at line 82 of file vtkCompositeDataSet.h.

◆ CopyStructure()

virtual void vtkCompositeDataSet::CopyStructure ( vtkCompositeDataSet * input )

virtual

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.

◆ SetDataSet()

virtual void vtkCompositeDataSet::SetDataSet	(	vtkCompositeDataIterator *	iter,
		vtkDataObject *	dataObj
	)

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 datasite with similar structure (achieved by using CopyStructure).

Implemented in vtkDataObjectTree, and vtkUniformGridAMR.

◆ GetDataSet()

virtual vtkDataObject * vtkCompositeDataSet::GetDataSet ( vtkCompositeDataIterator * iter )

pure virtual

Returns the dataset located at the positiong pointed by the iterator.

The iterator does not need to be iterating over this dataset itself. It can be an iterator for composite dataset with similar structure (achieved by using CopyStructure).

Implemented in vtkDataObjectTree, and vtkUniformGridAMR.

◆ GetActualMemorySize()

unsigned long vtkCompositeDataSet::GetActualMemorySize ( )

overridevirtual

Return the actual size of the data in kibibytes (1024 bytes).

This number is valid only after the pipeline has updated.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree.

◆ GetData() [1/2]

static vtkCompositeDataSet * vtkCompositeDataSet::GetData ( vtkInformation * info )

static

Retrieve an instance of this class from an information object.

◆ GetData() [2/2]

static vtkCompositeDataSet * vtkCompositeDataSet::GetData	(	vtkInformationVector *	v,
		int	i = `0`
	)

static

Retrieve an instance of this class from an information object.

◆ Initialize()

void vtkCompositeDataSet::Initialize ( )

overridevirtual

Restore data object to initial state,.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.

◆ ShallowCopy()

void vtkCompositeDataSet::ShallowCopy ( vtkDataObject * src )

overridevirtual

Shallow and Deep copy.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.

◆ DeepCopy()

void vtkCompositeDataSet::DeepCopy ( vtkDataObject * src )

overridevirtual

Shallow and Deep copy.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, vtkPartitionedDataSetCollection, and vtkUniformGridAMR.

◆ RecursiveShallowCopy()

virtual void vtkCompositeDataSet::RecursiveShallowCopy ( vtkDataObject * src )

pure virtual

For historical reasons, vtkCompositeDataSet::ShallowCopy simply pass pointers to the leaf non-composite datasets.

In some cases, we truly want to shallow copy those leaf non-composite datasets as well. For those cases, use this method.

Implemented in vtkDataObjectTree, and vtkUniformGridAMR.

◆ GetNumberOfPoints()

virtual vtkIdType vtkCompositeDataSet::GetNumberOfPoints ( )

virtual

Returns the total number of points of all blocks.

This will iterate over all blocks and call GetNumberOfPoints() so it might be expensive.

Reimplemented in vtkDataObjectTree.

◆ GetNumberOfCells()

virtual vtkIdType vtkCompositeDataSet::GetNumberOfCells ( )

virtual

Returns the total number of cells of all blocks.

This will iterate over all blocks and call GetNumberOfPoints() so it might be expensive.

Reimplemented in vtkDataObjectTree.

◆ GetNumberOfElements()

vtkIdType vtkCompositeDataSet::GetNumberOfElements ( int type )

overridevirtual

Get the number of elements for a specific attribute type (POINT, CELL, etc.).

Reimplemented from vtkDataObject.

◆ GetBounds()

void vtkCompositeDataSet::GetBounds ( double bounds[6] )

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. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED.

◆ NAME()

static vtkInformationStringKey * vtkCompositeDataSet::NAME ( )

static

Key used to put node name in the meta-data associated with a node.

◆ CURRENT_PROCESS_CAN_LOAD_BLOCK()

static vtkInformationIntegerKey * vtkCompositeDataSet::CURRENT_PROCESS_CAN_LOAD_BLOCK ( )

static

Key used to indicate that the current process can load the data in the node.

Used for parallel readers where the nodes are assigned to the processes by the reader to indicate further down the pipeline which nodes will be on which processes. THIS IS AN EXPERIMENTAL KEY SUBJECT TO CHANGE WITHOUT NOTICE

◆ GetDataSets()

template<class DataSetT = vtkDataSet>

static std::vector< DataSetT * > vtkCompositeDataSet::GetDataSets	(	vtkDataObject *	dobj,
		bool	preserveNull = `false`
	)

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.
