	// contains filtered or unexported fields
}

ModelWatcher implements two common methods for use by various facades - WatchForModelConfigChanges and ModelConfig.

func NewModelWatcher 

func NewModelWatcher(st state.ModelAccessor, resources facade.Resources, authorizer facade.Authorizer) *ModelWatcher

NewModelWatcher returns a new ModelWatcher. Active watchers will be stored in the provided Resources. The two GetAuthFunc callbacks will be used on each invocation of the methods to determine current permissions. Right now, model tags are not used, so both created AuthFuncs are called with "" for tag, which means "the current model".

If a reboot flag is set on the machine, then that machine is expected to reboot (params.ShouldReboot). a reboot flag set on the machine parent or grandparent, will cause the machine to shutdown (params.ShouldShutdown). If no reboot flag is set, the machine should do nothing (params.ShouldDoNothing).

type RebootFlagClearer

RegisterNamed registers the given resource. Callers must supply a unique name for the given resource. It is an error to try to register another resource with the same name as an already registered name. (This could be softened that you can overwrite an existing one and it will be Stopped and replaced, but we don't have a need for that yet.) It is also an error to supply a name that is an integer string, since that collides with the auto-naming from Register.

func (*Resources) Stop 

func (rs *Resources) Stop(id string) error

Stop stops the resource with the given id and unregisters it. It returns any error from the underlying Stop call. It does not return an error if the resource has already been unregistered.
