## Detailed Description

RoutingEvent cached key for maps.

The key is used as a cache in RoutingEvent, that is, the RoutingEvent attributes could be modificated without the key changing. It is important for the key to remain stable as it used in the various event queue as the sorting attribute. The key should be updated only when the RoutingEvent is temporarily whidrawn from the queue.

Cached attributes: (used in that lexicographical order for sorting)

- 1 – `eventLevel`.
- 2 – `canRipple`.
- 3 – `priority`.
- 4 – `length`.
- 5 – `isHorizontal`.
- 6 – `axis`.
- 7 – `sourceU`.
- 8 – `net` (name).
- 9 – `id`.
- X – `slackenStrap` unused.
- X – `tracksNb` unused.

It is internally managed by RoutingEvent and the queue.
