How to get the unique identifier of a metadata field?

Question

For example, the Profile has the field applicationVisibilities, which has the unique value inside application (see below). This identifies an application visibility. Another example: customPermissions has the unique value "name" per custom permission.

<applicationVisibilities>
  <!-- This --><application>standard__AllTabSet</application>
  <default>true</default>
  <visible>true</visible>
</applicationVisibilities>

Is it possible to get this information via API (pro grammatically)? I request Profile.applicationVisibilities and get application back?

Answer 1

It depends on what you want to get.

Here is the code to get list of Application Names for particular Profile

String profileName = 'System Administrator';
Profile p = [
        SELECT Id
        FROM Profile
        WHERE Name = :profileName
];

List<SetupEntityAccess> setupEntityAccesses = [
        SELECT Id, SetupEntityId
        FROM SetupEntityAccess
        WHERE Parent.ProfileId = :p.Id AND SetupEntityType = 'TabSet'
];

Set<Id> ids = new Set<Id>();
for (SetupEntityAccess setupEntityAccess : setupEntityAccesses) {
    ids.add(setupEntityAccess.SetupEntityId);
};

List<AppMenuItem> menuItems = [
        SELECT Id, Label
        FROM AppMenuItem
        WHERE ApplicationId IN :ids
];

List<String> applicationNames = new List<String>();

for (AppMenuItem appMenuItem : menuItems) {
    applicationNames.add(appMenuItem.Label);
}
