An event that is emitted whenever this handle changes the shape of a feature.
EditShape
An event that is emitted whenever this handle is invalidated.
Invalidated
A collection of edit handles that become active one-by-one.
As opposed to CompositeEditHandle, only one handle is active at a time. Once a handle finishes, the next one becomes active.
This can be especially useful for creation. Every step of the creation process corresponds to one handle. When the first handle deactivates, the next handle is used, and so on. A CreateByTemplateHandle is an example of a cascading handle. First, a point is created to position the template. After the template is positioned, the CreateByTemplateHandle delegates to the shape's edit handles so the user can further adapt the template to the desired shape.
