Member Function Documentation

static vtkCompositeDataIterator* vtkCompositeDataIterator::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

Reimplemented in vtkHierarchicalBoxDataIterator.

virtual const char* vtkCompositeDataIterator::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

Reimplemented in vtkHierarchicalBoxDataIterator.

static int vtkCompositeDataIterator::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

Reimplemented in vtkHierarchicalBoxDataIterator.

virtual int vtkCompositeDataIterator::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

Reimplemented in vtkHierarchicalBoxDataIterator.

static vtkCompositeDataIterator* vtkCompositeDataIterator::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkObject.

Reimplemented in vtkHierarchicalBoxDataIterator.

void vtkCompositeDataIterator::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 vtkObject.

Reimplemented in vtkHierarchicalBoxDataIterator.

virtual void vtkCompositeDataIterator::SetDataSet ( vtkCompositeDataSet * ds ) [virtual]

Set the composite dataset this iterator is iterating over. Must be set before traversal begins.

virtual vtkCompositeDataSet* vtkCompositeDataIterator::GetDataSet ( ) [virtual]

Set the composite dataset this iterator is iterating over. Must be set before traversal begins.

virtual void vtkCompositeDataIterator::InitTraversal ( ) [virtual]

Begin iterating over the composite dataset structure.

virtual void vtkCompositeDataIterator::InitReverseTraversal ( ) [virtual]

Begin iterating over the composite dataset structure in reverse order.

virtual void vtkCompositeDataIterator::GoToFirstItem ( ) [virtual]

Move the iterator to the beginning of the collection.

virtual void vtkCompositeDataIterator::GoToNextItem ( ) [virtual]

Move the iterator to the next item in the collection.

virtual int vtkCompositeDataIterator::IsDoneWithTraversal ( ) [virtual]

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.

virtual vtkDataObject* vtkCompositeDataIterator::GetCurrentDataObject ( ) [virtual]

Returns the current item. Valid only when IsDoneWithTraversal() returns 0.

virtual vtkInformation* vtkCompositeDataIterator::GetCurrentMetaData ( ) [virtual]

Returns the meta-data associated with the current item. This will allocate a new vtkInformation object is none is already present. Use HasCurrentMetaData to avoid unnecessary creation of vtkInformation objects.

virtual int vtkCompositeDataIterator::HasCurrentMetaData ( ) [virtual]

Returns if the a meta-data information object is present for the current item. Return 1 on success, 0 otherwise.

virtual void vtkCompositeDataIterator::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 vtkCompositeDataIterator::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 vtkCompositeDataIterator::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 vtkCompositeDataIterator::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 vtkCompositeDataIterator::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 vtkCompositeDataIterator::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 vtkCompositeDataIterator::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 vtkCompositeDataIterator::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.

virtual void vtkCompositeDataIterator::SetSkipEmptyNodes ( int ) [virtual]

If SkipEmptyNodes is true, then NULL datasets will be skipped. Default is true.

virtual int vtkCompositeDataIterator::GetSkipEmptyNodes ( ) [virtual]

If SkipEmptyNodes is true, then NULL datasets will be skipped. Default is true.

virtual void vtkCompositeDataIterator::SkipEmptyNodesOn ( ) [virtual]

If SkipEmptyNodes is true, then NULL datasets will be skipped. Default is true.

virtual void vtkCompositeDataIterator::SkipEmptyNodesOff ( ) [virtual]

If SkipEmptyNodes is true, then NULL datasets will be skipped. Default is true.

unsigned int vtkCompositeDataIterator::GetCurrentFlatIndex ( )

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.

virtual int vtkCompositeDataIterator::GetReverse ( ) [virtual]

Returns if the iteration is in reverse order.

void vtkCompositeDataIterator::NextInternal ( ) [protected]
