Note

Advanced Audience Targeting and audience segment qualification methods are currently in beta. Contact your Customer Success Manager for more information or register now on Optimizely.com.

fetchQualifiedSegments

Minimum SDK Version

4.0.0-beta

Description

You can use the fetchQualifiedSegments method to retrieve the external audience mapping for a specific user from the ODP server. The Optimizely Feature Experimentation Java SDK provides a synchronous and asynchronous version of the Optimizely Data Platform (ODP) fetchQualifiedSegments method.

• The SDK blocks the caller until it has completed the synchronous fetch.
• The SDK does not block the caller of asynchronous API.

fetchQualfiedSegments is a method of the UserContext object. See OptimizelyUserContext for details.

Parameters

The following table describes the parameters for the fetchQualifiedSegments method:

Returns - Synchronous call

The fetchQualifiedSegments synchronous method returns true if the qualified segments array in the user context was updated.

Returns - Asynchronous call

• If the fetch completes successfully, the Java SDK updates the qualified segments array in the user context and then calls the completion handler with a success status.
• If the fetch fails, the SDK calls the handler with a failure status.

If the Java SDK does not find an ODP audience in the datafile, it returns an empty qualified segments array without sending a request to the ODP server.

📘

Note

You can read and write directly to the qualified segments array instead of calling fetchQualifiedSegments.

This allows for bypassing the remote fetching process from ODP or for utilizing your own fetching service. This can be helpful when testing or debugging.

Example fetchQualifiedSegments call

The code creates a user context by instantiating an OptimizelyUserContext object with a user ID "user123" and a set of attributes which includes an "app_version" attribute with a value of "1.3.2".

The next section of the code shows the use of thefetchQualifiedSegments method to fetch all qualified segments with and without segment options.

After that, the code uses the decide method to make a decision on whether to show the feature flag with the key "flag1" to the user. Finally, the SDK calls the trackEvent method to track a custom event called "myevent".

Map<String, Object> attributes = new HashMap<>();
attributes.put("app_version", "1.3.2");
OptimizelyUserContext user = optimizely.createUserContext("user123", attributes);

// Without segment option 
Boolean response = user.fetchQualifiedSegments((Boolean isFetchSuccessful) -> {
  System.out.println(isFetchSuccessful);
            
  OptimizelyDecision decision = user.decide("flag1");
  user.trackEvent("purchase_event");
});

// With segment options
List<ODPSegmentOption> odpSegmentOptions = new ArrayList<>();
odpSegmentOptions.add(ODPSegmentOption.IGNORE_CACHE);
odpSegmentOptions.add(ODPSegmentOption.RESET_CACHE);

user.fetchQualifiedSegments((Boolean isFetchSuccessful) -> {
  System.out.println(isFetchSuccessful);
            
  OptimizelyDecision decision = user.decide("flag1");
  user.trackEvent("purchase_event");
}, odpSegmentOptions);

Map<String, Object> attributes = new HashMap<>();
attributes.put("app_version", "1.3.2");
OptimizelyUserContext user = optimizely.createUserContext("user123", attributes);

// Without segment options 
Boolean response = user.fetchQualifiedSegments();

// With segment options
List<ODPSegmentOption> odpSegmentOptions = new ArrayList<>();
odpSegmentOptions.add(ODPSegmentOption.IGNORE_CACHE);
odpSegmentOptions.add(ODPSegmentOption.RESET_CACHE);

Boolean response = user.fetchQualifiedSegments(odpSegmentOptions);

OptimizelyDecision decision = user.decide("flag1");
user.trackEvent("myevent");

The SDK catches any fetched segments. This means that if the same user requests the segments again (when creating new user contexts), the SDK can retrieve the audience segment information from the cache rather than from the remote ODP server. --comment still not sure if it's the SDK or "you" here

You can bypass caching using the following options with your odpSegmentOptions array:

• IGNORE_CACHE – Bypass segments cache for lookup and save.
• RESET_CACHE – Reset all segments cache.

isQualifiedFor

Minimum SDK Version

4.0.0-beta

Description

Check if the user is qualified for the given audience segment.

Parameters

The following table describes the parameters for the isQualifiedFor method:

Returns

true if the user is qualified.

Examples

The following is an example of whether or not the user is qualified for an ODP segment:

Map<String, Object> attributes = new HashMap<>();
attributes.put("laptop_os", "mac");
OptimizelyUserContext user = optimizely.createUserContext("user123", attributes);

Boolean response = user.fetchQualifiedSegments();
Boolean isQualified = user.isQualifiedFor("segment1");
