virtual vtkTypeBool 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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkDataObjectTreeIterator, vtkHierarchicalBoxDataIterator, and vtkUniformGridAMRDataIterator.

◆ PrintSelf()

void vtkCompositeDataIterator::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 vtkDataObjectTreeIterator, vtkHierarchicalBoxDataIterator, and vtkUniformGridAMRDataIterator.

◆ SetDataSet()

virtual void vtkCompositeDataIterator::SetDataSet ( vtkCompositeDataSet * ds )

Set the composite dataset this iterator is iterating over.

Must be set before traversal begins.

pure 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.

Implemented in vtkDataObjectTreeIterator, and vtkUniformGridAMRDataIterator.

virtual int vtkCompositeDataIterator::HasCurrentMetaData ( )

pure virtual

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

Return 1 on success, 0 otherwise.

Implemented in vtkDataObjectTreeIterator, and vtkUniformGridAMRDataIterator.

◆ SetSkipEmptyNodes()

virtual void vtkCompositeDataIterator::SetSkipEmptyNodes ( vtkTypeBool )

virtual

If SkipEmptyNodes is true, then nullptr datasets will be skipped.

virtual

If SkipEmptyNodes is true, then nullptr datasets will be skipped.

Default is true.

◆ SkipEmptyNodesOff()

virtual void vtkCompositeDataIterator::SkipEmptyNodesOff ( )

virtual

If SkipEmptyNodes is true, then nullptr datasets will be skipped.

Default is true.

◆ GetCurrentFlatIndex()

pure virtual

Flat index is an index to identify the data in a composite data structure.

Implemented in vtkDataObjectTreeIterator, and vtkUniformGridAMRDataIterator.

◆ GetReverse()
