Detailed Description
Maintains a collection of vtkUndoElement that can be undone/redone in a single step.
This is a concrete class that stores a collection of vtkUndoElement objects. A vtkUndoSet object represents an atomic undo-redoable operation. It can contain one or more vtkUndoElement objects. When added vtkUndoElement objects to a vtkUndoSet they must be added in the sequence of operation. When undoing the operations are performed in reverse order, while when redoing they are performed in forward order.
vtkUndoElement, vtkUndoSet and vtkUndoStack form the undo/redo framework core.

Member Function Documentation
| static vtkUndoSet* vtkUndoSet::New | ( | ) | [static] |
Reimplemented from vtkObject.
| virtual const char* vtkUndoSet::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkObject.
| static vtkUndoSet* vtkUndoSet::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkObject.
| void vtkUndoSet::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Reimplemented from vtkObject.
| virtual int vtkUndoSet::Undo | ( | ) | [virtual] |
Perform an Undo.
| virtual int vtkUndoSet::Redo | ( | ) | [virtual] |
Perform a Redo.
| int vtkUndoSet::AddElement | ( | vtkUndoElement * | elem | ) |
Add an element to this set. If the newly added element, elem, and the most recently added element are both Mergeable, then an attempt is made to merge the new element with the previous one. On successful merging, the new element is discarded, otherwise it is appended to the set.
- Returns:
- the index at which the element got added/merged.
| void vtkUndoSet::RemoveElement | ( | int | index | ) |
Remove an element at a particular index.
| vtkUndoElement* vtkUndoSet::GetElement | ( | int | index | ) |
Get an element at a particular index
| void vtkUndoSet::RemoveAllElements | ( | ) |
Remove all elemments.
| int vtkUndoSet::GetNumberOfElements | ( | ) |
Get number of elements in the set.
