Public Methods
| Name | Description | |
|---|---|---|
 | AddObserver | Register an object as an observer of changes to this object. (Inherited from Northwoods.Go.GoObject) |
| AddPoint | Overloaded. Add another point to the end of this stroke. (Inherited from Northwoods.Go.GoStroke) |
| AddSelectionHandles | Overridden. Unlike a normal GoStroke the end handles are in the shape of diamonds if Relinkable is true. |
| CalculateArrowhead | Modify an array of points to hold the four points of a polygon outlining an arrowhead (Inherited from Northwoods.Go.GoStroke) |
| CalculateRoute | This implementation of IGoRoutable just calls CalculateStroke to determine a new path (i.e. a new set of points) for this link. |
| CalculateStroke | This method is responsible for determining the points in the stroke, given the positions of the ports. |
| CanCopy | Called to see if the user can copy this object. (Inherited from Northwoods.Go.GoObject) |
| CanDelete | Called to see if the user can delete this object. (Inherited from Northwoods.Go.GoObject) |
| CanEdit | Called to see if the user can edit this object. (Inherited from Northwoods.Go.GoObject) |

| CanReshape | Called to see if the user can reshape this object. (Inherited from Northwoods.Go.GoObject) |
| CanResize | Called to see if the user can resize this object. (Inherited from Northwoods.Go.GoObject) |
| CanSelect | Called to see if the user can select this object. (Inherited from Northwoods.Go.GoObject) |
| CanView | Called to see if the user can see this object. (Inherited from Northwoods.Go.GoObject) |
| Changed | Overridden. If one of the stroke's points has changed, we notify this link's AbstractLink about the change, so that it has a chance to recalculate its stroke. |
| ChangeValue | Overridden. Performs changes for undo and redo. |
| Changing | Notify this object's document or view that some part of this object's state is about to be changed. (Inherited from Northwoods.Go.GoObject) |
| ClearPoints | Remove all of the points for this stroke. (Inherited from Northwoods.Go.GoStroke) |
| ComputeMove | Calculate a new location for this object. (Inherited from Northwoods.Go.GoObject) |

| Copy | This convenience method just makes a copy of the object itself, using a generic GoCopyDictionary. (Inherited from Northwoods.Go.GoObject) |
| CopyNewValueForRedo | Copies state to permit a redo. (Inherited from Northwoods.Go.GoStroke) |
| CopyObject | Overridden. Copying a link does not immediately set the IGoLink.FromPort and IGoLink.ToPort of the copied link, but does add the link to the copy dictionary's Delayeds collection so that later processing can set those properties. |
