CloudBees Feature Management is an advanced feature flagging solution that lets your development teams quickly build and deploy applications without compromising on safety.

Features

  • Mobile-first: CloudBees Feature Management is the first feature flagging system built from the ground up to run directly inside phones, tablets, and wearables.

  • Simple: CloudBees Feature Management allows developers to focus on their business logic and not working with the complex configurations on the dashboard.

  • Modern: Using static types, the compiler and IDE are responsible to prevent collisions to allow easy flags discovery by developers (by autocomplete).

  • Support Optimizations: CloudBees Feature Management unique proposition is that is supports the company needs a full capable experimentation system, for A/B/N testing, optimizations, customizations and more.

  • Remote configuration included: CloudBees Feature Management include a remote configuration module that allows developers to define a configuration that can be controlled from the server.

Classes

Classes Description

ROXBaseContainer

Contains configurations and flags.

ROXCore

Acts as a facade interface.

ROXExperiment

ROXRemoteVariable

Contains remote variables.

ROXReportingValue

Contains data about values of an Experiment.

ROXTargetGroup

Contains session data about a Target Group.

ROXBaseContainer

@interface ROXBaseContainer : NSObject

A container class for configurations and flags.

Any class that inherits from this base class can be used as an entry point for flags and configurations that are controlled by CloudBees Feature Management. To use an instance of this class, you need to register the instance using the [ROXCore register:]` method and retrieve the instance using `[ROXCore get:] method.

Methods Description Declaration

-namespace

Override this property to override the default namespace of a class.

(NSString *)namespace;

ROXCore

ROXCore class is a static objc class that acts as a facade interface.

You use this flag for the following:

  • Initialize CloudBees Feature Management SDK using +setupWithKey:

  • Register container instances using +register:

  • Retrieve container instances using +getContainer:

  • Load custom properties with setCustomPropertyKey:value: methods

  • Present the flags view controller with +flagsViewController

Methods Description Declaration Parameter

setupWithKey:

Loads the SDK, usually called as part of -[AppDelegate application:didFinishLaunchingWithOptions:]

(void)setupWithKey:(NSString *)roxKey;

roxKey The app key (taken from ROX dashboard)

setupWithKey:options:

Loads the SDK, usually called as part of -[AppDelegate application:didFinishLaunchingWithOptions:]

(void)setupWithKey:(NSString *)roxKey options:(ROXOptions *)options;

roxKey The app key (taken from CloudBees Feature Management dashboard)

options setup options

register:

Register a container instance to CloudBees Feature Management system, the same instance can be retrieved by using +getContainer: function

@params container The instance to register, this instance values are set at +sync, +setupWithKey:, or a if the app goes into foreground NOTE: This method should be called only once for a given class.

+ (void) register:(ROXBaseContainer *)container;

container

getContainer:

Retrieve an instance from type clazz that was registered with ROX.register(_:)

+ (NSObject *)getContainer:(Class)clazz;

clazz The type of instance you want to retrieve

Return Value The instance that was registered

sync

Recalculate the rules of experiments allocation base on new data [NOTE] Usually called after the user has logged in to refresh ROX custom properties

+ (void)sync;

unfreeze

Unfreeze the state of all flags in code

When a flag is used in code, his value gets frozen in the app until the next app foreground event. Calling this function will unfreeze all flags, and using a flag will return it’s most updated value

+ (void)unfreeze;

flagsViewController

A view to control feature flags values locally on a mobile device or simulator.

CloudBees Feature Management ViewController allows developers, QA, or internal employees (depending on policy) to view, disable, enable and reset the state of their flags locally on the device. The functions return a view controller that can be loaded to the view hierarchy for test devices upon shake, or by triggering an existing debug view in the app.

+ (id)flagsViewController; Return Value ViewController which shows the local feature flags and provides an interface to turn them on or off.
