FeatureFlagDataProvider

STATUS: ACTIVE

This class is responsible for querying / fetching FeatureFlag data. This is separate from the FeatureFlag flag class to facilitate proper unit testing. (and just good design)

Group FeatureFlag

Constructors

public FeatureFlagDataProvider()

Default constructor. Pulls the custom metadata records without soql.

---

Fields

public featureFlags → Map<String,Feature_Flag__mdt>

Fetch the feature flags from custom metadata.

private mFeatureFlagsById → Map<String,Feature_Flag__mdt>

memoized map of feature flags by id

private mPerCustomPermissionOverridesByFeatureFlag → Map<String,List<FF_Enabled_For_Custom_Permission__mdt>>

TESTVISIBLE

memoized map of per-custom permission overrides by feature flag name

private mPerPermSetOverridesByFeatureFlag → Map<String,List<Feature_Flag_Enabled_For__mdt>>

TESTVISIBLE

Memoized map of per-permission set overrides by feature flag name

public perCustomPermissionOverrides → Map<String,FF_Enabled_For_Custom_Permission__mdt>

Fetch the per-custom permission overrides from custom metadata.

private perPermSetOverrides → Map<String,Feature_Flag_Enabled_For__mdt>

Fetch the per-permission set overrides from custom metadata.

---

Properties

private featureFlagsById → Map<String,Feature_Flag__mdt>

Returns a map of known feature flag metadata records keyed by the record id, rather than the record's label.

public perCustomPermissionOverridesByFeatureFlag → Map<String,List<FF_Enabled_For_Custom_Permission__mdt>>

Used to correlate related metadata records for per-custom permission enablement of features without having to burn a soql query to do so.

public perPermSetOverridesByFeatureFlag → Map<String,List<Feature_Flag_Enabled_For__mdt>>

Used to correlate related metadata records for per-permission set enablement of features without having to burn a soql query to do so.

Methods

public Set enablingPermissionSets(String featureFlagName)

Returns set of ids corresponding to permission set ids that provide feature enablement for the indicated feature flag

Parameters

Param	Description
featureFlagName	Name of the feature flag to calculate Perm Set Ids

Returns

Type	Description
Set	Set<Id> of permission set ids

public Set enablingCustomPermissions(String featureFlagName)

Returns set of Strings representing custom permission names that provide feature enablement for the indicated feature flag

Parameters

Param	Description
featureFlagName	Name of the feature flag to calculate custom permission names

Returns

Type	Description
Set	Set<String> of custom permission names

public List fetchUsersAssignedPermissionSets()

Used to find a users' assigned permission set ids. This is intentionally tied to the executing users' userId.

Returns

Type	Description
List	List<Id> a list of permission set id's assigned to the current user

private void overrideFlags(Map<String,Feature_Flag__mdt> flags)

TESTVISIBLE

Allows testers to inject custom metadata records that are not present in the org

Parameters

Param	Description
flags	Map of flags to override this class' loading of custom metadata for flags

private void overridePerPermSetOverrides(Map<String,Feature_Flag_Enabled_For__mdt> perPermSetOverrides)

TESTVISIBLE

Allows testers to inject custom metadata records that are not present in the org

Parameters

Param	Description
perPermSetOverrides	Map of flags to override this class' loading of custom metadata for per-permission set enablement of features

private void overridePerCustomPermissionOverrides(Map<String,FF_Enabled_For_Custom_Permission__mdt> perCustomPermissionOverrides)

TESTVISIBLE

Allows testers to inject custom metadata records that are not present in the org

Parameters

Param	Description
perCustomPermissionOverrides	Map of flags to override this class' loading of custom metadata for per-custom-permission enablement of features

private static Map rekeyMapByFeatureFlagName(Map<String,SObject> incomingMap, Map<String,List<SObject>> memoizedMap, Map<String,Feature_Flag__mdt> correlatingMap, String keyField)

SUPPRESSWARNINGS

given an incoming map, create and return a new map where the keys are a from the correlation map and the values are the values of the incoming map. Uses a memoized map for building and is intended to be used with a memoization pattern.

Parameters

Param	Description
incomingMap	This is the map that will provide the values to the resulting map.
memoizedMap	This is the 'working' or memoized map that is iteratively built and ultimately returned.
correlatingMap	This map provides the keys for the returned map
keyField	This is the field used to correlate the incoming map with the corresponding correlation map

Returns

Type	Description
Map<String,List>	Map<String, List<sObject>>
