class NodeShutdownCoordinator

Defined at line 82 of file ../../src/devices/bin/driver_manager/shutdown/node_shutdown_coordinator.h

Coordinates and keeps track of the node's shutdown process.

void Remove (std::shared_ptr<Node> node, RemovalSet removal_set, NodeRemovalTracker * removal_tracker)

Begin the removal process for a Node. This function ensures that a Node is

only removed after all of its children are removed. It also ensures that

a Node is only removed after the driver that is bound to it has been stopped.

This is safe to call multiple times.

There are multiple reasons a Node's removal will be started:

- The system is being stopped.

- The Node had an unexpected error or disconnect

During a system stop, Remove is expected to be called twice:

once with |removal_set| == kPackage, and once with |removal_set| == kAll.

Errors and disconnects that are unrecoverable should call Remove(kAll, nullptr).

void ResetShutdown ()

Reset the shutdown values. Should only be called after shutdown is complete.

void set_shutdown_intent (ShutdownIntent intent)

TODO(https://fxbug.dev/42082343): Handle shutdown intent priority. Currently it's possible

for rebind or restart to override a a removal in process.

void PerformTransition (fit::function<void ()> action)

Invokes |action|, which is the actions for transitioning to the next

another state. If |kEnableShutdownDelay| is true and generates a randomized

delay, then the action is invoked asynchronously with the delay.
