	// contains filtered or unexported fields

API implements the charms interface and is the concrete implementation of the API end point.

func NewCharmsAPI

func NewCharmsAPI(
	authorizer facade.Authorizer,
	st charmsinterfaces.BackendState,
	m charmsinterfaces.BackendModel,
	csResolverFunc CSResolverGetterFunc,
	getStrategyFunc func(source string) StrategyFunc,
	newStorage func(modelUUID string, session *mgo.Session) storage.Storage,
) (*API, error)

func NewFacadeV4

func NewFacadeV4(ctx facade.Context) (*API, error)

NewFacadeV4 provides the signature required for facade V4 registration.

func (*API) AddCharm

AddCharm adds the given charm URL (which must include revision) to the environment, if it does not exist yet. Local charms are not supported, only charm store and charm hub URLs. See also AddLocalCharm().

CheckCharmPlacement checks if a charm is allowed to be placed with in a given application.

func (*API) IsMetered

func (a *API) IsMetered(args params.CharmURL) (params.IsMeteredResult, error)

IsMetered returns whether or not the charm is metered.

func (*API) List

func (a *API) List(args params.CharmsList) (params.CharmsListResult, error)

List returns a list of charm URLs currently in the state. If supplied parameter contains any names, the result will be filtered to return only the charms with supplied names.

func (*API) ResolveCharms

ResolveCharms resolves the given charm URLs with an optionally specified preferred channel. Channel provided via CharmOrigin.
