Private Properties

Method	Description
ClearHistory ( ) : void	Clears the history of edit operations.
DrawEditingGeometry ( Graphics g, MapToClientDelegate mapToClient, int offsetX, int offsetY ) : void	Draws editing geometry.

Redo ( ) : void	Redo edit action.
RemoveActiveNode ( ) : void	Removes the active node.
RemoveActivePatch ( ) : void	Removes the active patch.
RemovePatch ( int patchIndex ) : void	Removes specified coordinate patch.
ReplaceGeometry ( IGeometry newGeometry ) : void	Replaces currently editing geometry with the other one.
TryActivateNodeAt ( ICoordinate coordinate, double nodeSize ) : bool	Tries to activate a node at the specified position.
TryAddNode ( ICoordinate coordinate ) : bool	Tries to add a new node into editing geometry.
Undo ( ) : void	Undo edit action.
UpdateActiveNodePosition ( ICoordinate coordinate, bool commitIntoUndoList ) : bool	Updates the position of the active node with the specified value
