class vtkDataObjectTreeIterator
 

Detailed Description

provides implementation for most abstract methods in the superclass vtkCompositeDataSet

vtkDataObjectTree is represents a collection of datasets (including other composite datasets). It provides an interface to access the datasets through iterators. vtkDataObjectTree provides methods that are used by subclasses to store the datasets. vtkDataObjectTree provides the datastructure for a full tree representation. Subclasses provide the semantics for it and control how this tree is built.

Member Function Documentation

static vtkTypeBool vtkDataObjectTree::IsTypeOf ( const char *  type)
static
virtual vtkTypeBool vtkDataObjectTree::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.

Reimplemented from vtkCompositeDataSet.

Reimplemented in vtkMultiBlockDataSet, vtkPartitionedDataSet, vtkMultiPieceDataSet, and vtkPartitionedDataSetCollection.

static vtkDataObjectTree* vtkDataObjectTree::SafeDownCast ( vtkObjectBase o)
static
virtual vtkObjectBase* vtkDataObjectTree::NewInstanceInternal ( ) const
protectedvirtual
vtkDataObjectTree* vtkDataObjectTree::NewInstance ( ) const
void vtkDataObjectTree::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 vtkCompositeDataSet.

Reimplemented in vtkMultiBlockDataSet, vtkPartitionedDataSet, vtkMultiPieceDataSet, and vtkPartitionedDataSetCollection.

virtual vtkDataObjectTreeIterator* vtkDataObjectTree::NewTreeIterator ( )
virtual

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

vtkCompositeDataIterator* vtkDataObjectTree::NewIterator ( )
overridevirtual

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

Use NewTreeIterator when you have a pointer to a vtkDataObjectTree and NewIterator when you have a pointer to a vtkCompositeDataSet; NewIterator is inherited and calls NewTreeIterator internally.

Implements vtkCompositeDataSet.

void vtkDataObjectTree::CopyStructure ( vtkCompositeDataSet input)
overridevirtual

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.

Implements vtkCompositeDataSet.

void vtkDataObjectTree::SetDataSet ( vtkCompositeDataIterator iter,
vtkDataObject dataObj 
)
overridevirtual

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).

Implements vtkCompositeDataSet.

void vtkDataObjectTree::SetDataSetFrom ( vtkDataObjectTreeIterator iter,
vtkDataObject dataObj 
)

Sets the data at the location provided by a vtkDataObjectTreeIterator.

vtkDataObject* vtkDataObjectTree::GetDataSet ( vtkCompositeDataIterator iter)
overridevirtual

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).

Implements vtkCompositeDataSet.

virtual vtkInformation* vtkDataObjectTree::GetMetaData ( vtkCompositeDataIterator iter)
virtual

Returns the meta-data associated with the position pointed by the iterator.

This will create a new vtkInformation object if none already exists. Use HasMetaData to avoid creating the vtkInformation object unnecessarily. 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).

Reimplemented in vtkMultiBlockDataSet, vtkPartitionedDataSet, and vtkPartitionedDataSetCollection.

virtual int vtkDataObjectTree::HasMetaData ( vtkCompositeDataIterator iter)
virtual

Returns if any meta-data associated with the position 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).

Reimplemented in vtkMultiBlockDataSet, vtkPartitionedDataSet, and vtkPartitionedDataSetCollection.

unsigned long vtkDataObjectTree::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 vtkCompositeDataSet.

void vtkDataObjectTree::Initialize ( )
overridevirtual

Restore data object to initial state,.

Reimplemented from vtkCompositeDataSet.

void vtkDataObjectTree::ShallowCopy ( vtkDataObject src)
overridevirtual

Shallow and Deep copy.

Reimplemented from vtkCompositeDataSet.

void vtkDataObjectTree::DeepCopy ( vtkDataObject src)
overridevirtual

Shallow and Deep copy.

Reimplemented from vtkCompositeDataSet.

vtkIdType vtkDataObjectTree::GetNumberOfPoints ( )
overridevirtual

Returns the total number of points of all blocks.

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

Reimplemented from vtkCompositeDataSet.

vtkIdType vtkDataObjectTree::GetNumberOfCells ( )
overridevirtual

Returns the total number of cells of all blocks.

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

Reimplemented from vtkCompositeDataSet.

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

Retrieve an instance of this class from an information object.

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

Retrieve an instance of this class from an information object.

void vtkDataObjectTree::SetNumberOfChildren ( unsigned int  num)
protected

Set the number of children.

unsigned int vtkDataObjectTree::GetNumberOfChildren ( )
protected

Get the number of children.

void vtkDataObjectTree::SetChild ( unsigned int  index,
vtkDataObject  
)
protected

Set child dataset at a given index.

The number of children is adjusted to to be greater than the index specified.

void vtkDataObjectTree::RemoveChild ( unsigned int  index)
protected

Remove the child at a given index.

vtkDataObject* vtkDataObjectTree::GetChild ( unsigned int  num)
protected

Returns a child dataset at a given index.

vtkInformation* vtkDataObjectTree::GetChildMetaData ( unsigned int  index)
protected

Returns the meta-data at a given index.

If the index is valid, however, no information object is set, then a new one will created and returned. To avoid unnecessary creation, use HasMetaData().

void vtkDataObjectTree::SetChildMetaData ( unsigned int  index,
vtkInformation info 
)
protected

Sets the meta-data at a given index.

int vtkDataObjectTree::HasChildMetaData ( unsigned int  index)
protected

Returns if meta-data information is available for the given child index.

Returns 1 is present, 0 otherwise.
