Is it possible to query the Apex Class Accesses of a permission set?

Question

I'm not sure about the object name and the Field Name. I tried but i think "ApexClass" is not the right object to call apexclass from a permission set. Here is the query [Select Id, Name From ApexClass] but its not giving the enabled classes in a permissionSet.

Thanks in Advance

Answer 1

You can use SetupEntityAccess and Apex class to get required information.

First SOQL will show all apex class Ids which is enabled for permission set 'CustomPermission'.

Second SOQL will show Apex Class Name based on first query result.

Map<ID,AggregateResult> mapAccess=new Map<Id, AggregateResult>([SELECT SetupEntityId Id
FROM SetupEntityAccess where Parent.Name='CustomPermission' and SetupEntityType='ApexClass' GROUP By SetupEntityId]);

List<ApexClass> apexClasses=[Select Name from Apexclass where id in:mapAccess.keyset()];

System.debug(apexClasses);

As per the documentation of SetupEntityAccess at https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_objects_setupentityaccess.htm

SetupEntityAccess - Represents the enabled setup entity access settings (such as for Apex classes) for the parent PermissionSet

In this SetupEntityId represents the ID of the entity for which access is enabled, such as an Apex class or Visualforce page. SetupEntityType - ApexClass for Apex classes

Below code returns all permission sets that grant access to the helloWorld Apex class:

SELECT Id, Name,
   (SELECT Id, Parent.Name, Parent.Profile.Name
   FROM SetupEntityAccessItems)
FROM ApexClass
WHERE Name = 'helloWorld'
