type Machine

type Machine interface {
	InstanceStatus() (status.StatusInfo, error)
	Life() state.Life
	Status() (status.StatusInfo, error)
}

Machine represents a machine in a Juju model.

type Model

type Model interface {
	Life() state.Life
	ModelTag() names.ModelTag
	Status() (status.StatusInfo, error)
}

type State

type State interface {
	AllMachines() ([]Machine, error)
	AllModelUUIDs() ([]string, error)
	AllUsers() ([]User, error)
	ControllerTag() names.ControllerTag
	UserAccess(names.UserTag, names.Tag) (permission.UserAccess, error)
}

State represents the global state managed by the Juju controller.

type StatePool

type StatePool interface {
	SystemState() State
	Get(modelUUID string) (PooledState, error)
	GetModel(modelUUID string) (Model, state.PoolHelper, error)
}

StatePool represents a pool of State objects.

func NewStatePool

func NewStatePool(pool *state.StatePool) StatePool

NewStatePool takes a *state.StatePool, and returns a StatePool value backed by it.

type User
