Class PlanRollback

java.lang.Object

com.eqixiac.equinix.design.plan.PlanRollback

public final class PlanRollback
extends Object

Tears down resources a run created, in an order that cannot strand a billable Cloud Router.

1. Every connection (provider connections and backbone links) is deleted, newest first. A delete that answers HTTP 404 counts as already gone.
2. Each connection delete is then polled (with the core/waiter machinery, on the options' clock and poll interval) until the connection reads DEPROVISIONED or HTTP 404, for at most deleteTimeout. Fabric deletes connections asynchronously; deleting the Cloud Router while a connection is still DEPROVISIONING fails or orphans the router.
3. A Cloud Router is deleted only when every connection attached to it is confirmed gone, and its delete is polled the same way.

Routing protocols are removed by Fabric with their connection: they are reported removed when their connection is, and orphaned when it is not. Anything that could not be removed is an OrphanedResource with its uuid and the reason.
