Get Enabled Features
This topic describes the Get Enabled Features method, which retrieves a list of features that are enabled for the user.
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.
Version
SDK v3.0 and higher
Description
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.
Parameters
The table below lists the required and optional parameters in Java.
| Parameter | Type | Description |
|---|---|---|
| userId required | string | The ID of the user to check. |
| attributes optional | map | 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. |
Returns
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.
Examples
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);
