OptimizelyUserContext definition

The following code shows the object definition for OptimizelyUserContext:

                            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

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

Note

You must first enable the Advanced Audience Targeting integration to use the qualifiedSegments(), fetchQualifiedSegments(), and isQualifiedFor() methods. See Advanced Audience Targeting for more information.

Properties

The following table shows attributes for the OptimizelyUserContext object:

AttributeTypeComment
userIdStringThe ID of the user
(optional) attributesMapA 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:

MethodComment
setAttributePass a custom user attribute as a key-value pair to the user context.
decideReturns 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
decideAllReturns decisions for all active (unarchived) flags for a user.
See Decide methods
decideForKeysReturns a map of flag decisions for specified flag keys.
See Decide methods
trackEventTracks 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
setForcedDecisionForces a user into a specific variation.
See Set Forced Decision
getForcedDecisionReturns what variation the user was forced into.
See Get Forced Decision
removeForcedDecisionRemoves a user from a specific forced variation.
See Remove Forced Decision
removeAllForcedDecisionsRemoves a user from all forced variations.
See Remove All Forced Decisions
fetchQualifiedSegments **Fetch all Optimizely Data Platform (ODP) real-time segments that the user context qualified for. See Advanced Audience Targeting segment qualification methods for the Android SDK.
isQualifiedFor **Check if the user context qualified for a given ODP real-time segment. See Advanced Audience Targeting segment qualification methods for the Android SDK.

** Requires the Advanced Audience Targeting integration.
