Exception Edge
An exception edge is a type of activity edge drawn as a lighting bolt. It connects the executable node that is being protected by an exception handler to an exception input node on the border of the exception handler.
Explanation
An exception edge is a device for connecting an exception handler to the node (executable), which the exception handler is protecting. The node is typically an action and the line is drawn as a lightning bolt to a small input node on the boundary of the exception handler. The exception handler is best considered to be comprised of the exception edge, the input node and the body of the handler, which performs some action when the exception occurs. It is listed separately because of its distinctive appearance and also because it is commonly confused with an interruptible activity edge.
