-init

Init is unavailable. Dependencies must be injected using initWithConnectionManager:

Objective-C

- (nonnull instancetype)init;

-initWithConnectionManager:

Creates a new system capability manager with a specified connection manager

Objective-C

- (nonnull instancetype)initWithConnectionManager:
    (nonnull id<SDLConnectionManagerType>)manager;

Parameters

manager

A connection manager to use to forward on RPCs

-stop

Stops the manager. This method is used internally.

Objective-C

- (void)stop;

Swift

func stop()

-updateCapabilityType:completionHandler:

Retrieves a capability type from the remote system. This function must be called in order to retrieve the values for navigationCapability, phoneCapability, videoStreamingCapability, remoteControlCapability, and appServicesCapabilities. If you do not call this method first, those values will be nil. After calling this method, assuming there is no error in the handler, you may retrieve the capability you requested from the manager within the handler.

Objective-C

- (void)updateCapabilityType:(nonnull SDLSystemCapabilityType)type
           completionHandler:(nonnull SDLUpdateCapabilityHandler)handler;

Swift

func updateCapabilityType(_ type: SDLSystemCapabilityType, completionHandler handler: @escaping SDLUpdateCapabilityHandler)

Parameters

type

The type of capability to retrieve

handler

The handler to be called when the retrieval is complete
