Member Function Documentation

static vtkDataObjectTreeIterator* vtkDataObjectTreeIterator::New ( )

static

static int vtkDataObjectTreeIterator::IsTypeOf ( const char * type )

static

virtual int vtkDataObjectTreeIterator::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 vtkCompositeDataIterator.

static vtkDataObjectTreeIterator* vtkDataObjectTreeIterator::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkDataObjectTreeIterator::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkCompositeDataIterator.

vtkDataObjectTreeIterator* vtkDataObjectTreeIterator::NewInstance ( ) const

void vtkDataObjectTreeIterator::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 vtkCompositeDataIterator.

void vtkDataObjectTreeIterator::GoToFirstItem ( )

overridevirtual

Move the iterator to the beginning of the collection.

Implements vtkCompositeDataIterator.

void vtkDataObjectTreeIterator::GoToNextItem ( )

overridevirtual

Move the iterator to the next item in the collection.

Implements vtkCompositeDataIterator.

int vtkDataObjectTreeIterator::IsDoneWithTraversal ( )

overridevirtual

Test whether the iterator is finished with the traversal.

Returns 1 for yes, and 0 for no. It is safe to call any of the GetCurrent...() methods only when IsDoneWithTraversal() returns 0.

Implements vtkCompositeDataIterator.

vtkDataObject* vtkDataObjectTreeIterator::GetCurrentDataObject ( )

overridevirtual

Returns the current item.

Valid only when IsDoneWithTraversal() returns 0.

Implements vtkCompositeDataIterator.

vtkInformation* vtkDataObjectTreeIterator::GetCurrentMetaData ( )

overridevirtual

Returns the meta-data associated with the current item.

Note that, depending on iterator implementation, the returned information is not necessarily stored on the current object. So modifying the information is forbidden.

Implements vtkCompositeDataIterator.

int vtkDataObjectTreeIterator::HasCurrentMetaData ( )

overridevirtual

Returns if the a meta-data information object is present for the current item.

Return 1 on success, 0 otherwise.

Implements vtkCompositeDataIterator.

unsigned int vtkDataObjectTreeIterator::GetCurrentFlatIndex ( )

overridevirtual

Flat index is an index obtained by traversing the tree in preorder.

This can be used to uniquely identify nodes in the tree. Not valid if IsDoneWithTraversal() returns true.

Implements vtkCompositeDataIterator.

virtual void vtkDataObjectTreeIterator::SetVisitOnlyLeaves ( int )

virtual

If VisitOnlyLeaves is true, the iterator will only visit nodes (sub-datasets) that are not composite.

If it encounters a composite data set, it will automatically traverse that composite dataset until it finds non-composite datasets. With this options, it is possible to visit all non-composite datasets in tree of composite datasets (composite of composite of composite for example :-) ) If VisitOnlyLeaves is false, GetCurrentDataObject() may return vtkCompositeDataSet. By default, VisitOnlyLeaves is 1.

virtual int vtkDataObjectTreeIterator::GetVisitOnlyLeaves ( )

virtual

If VisitOnlyLeaves is true, the iterator will only visit nodes (sub-datasets) that are not composite.

If it encounters a composite data set, it will automatically traverse that composite dataset until it finds non-composite datasets. With this options, it is possible to visit all non-composite datasets in tree of composite datasets (composite of composite of composite for example :-) ) If VisitOnlyLeaves is false, GetCurrentDataObject() may return vtkCompositeDataSet. By default, VisitOnlyLeaves is 1.

virtual void vtkDataObjectTreeIterator::VisitOnlyLeavesOn ( )

virtual

If VisitOnlyLeaves is true, the iterator will only visit nodes (sub-datasets) that are not composite.

If it encounters a composite data set, it will automatically traverse that composite dataset until it finds non-composite datasets. With this options, it is possible to visit all non-composite datasets in tree of composite datasets (composite of composite of composite for example :-) ) If VisitOnlyLeaves is false, GetCurrentDataObject() may return vtkCompositeDataSet. By default, VisitOnlyLeaves is 1.

virtual void vtkDataObjectTreeIterator::VisitOnlyLeavesOff ( )

virtual

If VisitOnlyLeaves is true, the iterator will only visit nodes (sub-datasets) that are not composite.

If it encounters a composite data set, it will automatically traverse that composite dataset until it finds non-composite datasets. With this options, it is possible to visit all non-composite datasets in tree of composite datasets (composite of composite of composite for example :-) ) If VisitOnlyLeaves is false, GetCurrentDataObject() may return vtkCompositeDataSet. By default, VisitOnlyLeaves is 1.

virtual void vtkDataObjectTreeIterator::SetTraverseSubTree ( int )

virtual

If TraverseSubTree is set to true, the iterator will visit the entire tree structure, otherwise it only visits the first level children.

Set to 1 by default.

virtual int vtkDataObjectTreeIterator::GetTraverseSubTree ( )

virtual

If TraverseSubTree is set to true, the iterator will visit the entire tree structure, otherwise it only visits the first level children.

Set to 1 by default.

virtual void vtkDataObjectTreeIterator::TraverseSubTreeOn ( )

virtual

If TraverseSubTree is set to true, the iterator will visit the entire tree structure, otherwise it only visits the first level children.

Set to 1 by default.

virtual void vtkDataObjectTreeIterator::TraverseSubTreeOff ( )

virtual

If TraverseSubTree is set to true, the iterator will visit the entire tree structure, otherwise it only visits the first level children.

Set to 1 by default.

void vtkDataObjectTreeIterator::NextInternal ( )

protected

vtkDataObjectTreeIndex vtkDataObjectTreeIterator::GetCurrentIndex ( )

protected

Returns the index for the current data object.
