The OptimizelyUserContext object allows you to make flag decisions and track events for a user context that you have already created using the Create User Context method.

OptimizelyUserContext version

OptimizelyUserContext is supported on the Android SDK v3.7 and higher.

Forced decision methods version

setForcedDecision(), getForcedDecision(), removeForcedDecision() and removeAllForcedDecisions() methods are supported on v3.13 and higher.

OptimizelyUserContext definition

The following code shows the object definition for OptimizelyUserContext:

class OptimizelyUserContext(optimizely: Optimizely,
                            userId: String,
                            attributes: Map<String, Any?>?) {
    val userId: String
    val attributes: MutableMap<String?, Any?>

    // set an attribute for the user
    fun setAttribute(key: String, value: Any?)

    // make a decision about which flag variation the user buckets into for the flag key
    fun decide(key: String,
               options: List<OptimizelyDecideOption?>? = emptyList()): OptimizelyDecision

    // make decisions about which flag variations the user buckets into for flag keys

                      options: List<OptimizelyDecideOption?>? = emptyList()): Map<String, OptimizelyDecision>

    // make decisions about which flag variations the user buckets into for all flags
    fun decideAll(options: List<OptimizelyDecideOption?>? = emptyList()): Map<String, OptimizelyDecision>

    // track user event
    fun trackEvent(eventName: String,
                   eventTags: Map<String?, *>? = emptyMap<String?, Any>())

    // sets a forced decision (variationKey) for a given decision context

    public Boolean setForcedDecision(OptimizelyDecisionContext context, OptimizelyForcedDecision decision)

    // returns the forced decision (variationKey) for a given decision context
    public OptimizelyForcedDecision getForcedDecision(OptimizelyDecisionContext context)

    // removes the forced decision (variationKey) for a given decision context
    public Boolean removeForcedDecision(OptimizelyDecisionContext context)

    // removes all the forced decisions (variationKeys) for the user context
    public Boolean removeAllForcedDecisions()
}

Properties

The following table shows attributes for the OptimizelyUserContext object:

Attribute	Type	Comment
userId	String	The ID of the user
(optional) attributes	Map	A map of custom key-value pairs specifying attributes for the user that are used for audience targeting. You can pass the map with the user ID when you create the user.

Methods

The following table shows methods for the OptimizelyUserContext object:

Method	Comment
setAttribute	Pass a custom user attribute as a key-value pair to the user context.
decide	Returns a decision result for a flag key for a user. The decision result is returned in an OptimizelyDecision object, and contains all data required to deliver the flag rule. See Decide methods
decideAll	Returns decisions for all active (unarchived) flags for a user. See Decide methods
decideForKeys	Returns a map of flag decisions for specified flag keys. See Decide methods
trackEvent	Tracks a conversion event (in other words, an action a user takes) for a user. Logs an error message if the specified event key doesn't match any existing events. See Track Event
setForcedDecision	Forces a user into a specific variation. See Set Forced Decision
getForcedDecision	Returns what variation the user was forced into. See Get Forced Decision
removeForcedDecision	Removes a user from a specific forced variation. See Remove Forced Decision
removeAllForcedDecisions	Removes a user from all forced variations. See Remove All Forced Decisions
