Retrieves a list of features that are enabled for the user. Invoking this method is equivalent to running Is Feature Enabled for each feature in the datafile sequentially.
This method takes into account the user
attributes passed in, to determine if the user is part of the audience that qualifies for the experiment.
SDK v3.0 and higher
This method iterates through all feature flags and for each feature flag invokes Is Feature Enabled. If a feature is enabled, this method adds the feature’s key to the return list.
The table below lists the required and optional parameters in Java.
The ID of the user to check.
A map of custom key-value string pairs specifying attributes for the user that are used for audience targeting. Non-string values are only supported in the 3.0 SDK and above.
A list of keys corresponding to the features that are enabled for the user, or an empty list if no features could be found for the specified user.
This section shows a simple example of how you can use the method.
The Java example shows 3.0-specific functionality of passing in non-string attributes.
Map<String, Object> attributes = new HashMap<>(); attributes.put("DEVICE", "iPhone"); attributes.put("LIFETIME", 24738388); attributes.put("IS_LOGGED_IN", true); ArrayList<String> featureFlags = (ArrayList<String>) spyOptimizely.getEnabledFeatures(genericUserId, attributes);
The language/platform source files containing the implementation for Java is Optimizely.java.
