Which Objects are displayed in PermissionSet Object Settings?

Question

I am a noob with Salesforce, please bare with my question.

I am creating an App which enables easy edit/creation of PermissionSets on an ORG.

In this process, I am creating a tree view with

Permission Sets --> Objects + Permissions --> Fields + Permissions

Step 1. I have retrieved Permission Sets with SOQL

SELECT Id,Name,Description,NamespacePrefix,UserLicenseId,CreatedDate FROM PermissionSet

Step 2. I am retrieving Objects with Schema.getGlobalDescribe()

Here is my question, I am able to fetch all the objects from my ORG, but the object names does not match with the object names which we generally see in Permission Set --> Object Settings

For example:

With Schema.getGlobalDescribe(), I get the Object Names, something like this,

Label: Contract, Name: Contract

Label: Contract History, Name: ContractHistory

Label: Order, Name: Order

Label: Order Share, Name: OrderShare

but, in Permission Set -> Object Settings I see something like this,

Accounts    
App Launcher    
Assets  
Campaign Members    
Campaigns   
Cases   
Chatter 
Coaching    
Coaching    
Contacts    
Content 
Contracts

All I need is same set of object Names as we see in Permission Set -> Object Settings

I read that the object names displayed in Permission Set -> Object Settings are the whole set of objects from ORG but, I see some of them are missing and some are different with just being singular to plural like,

From my code: "Case"

From Permission Set --> Object Settings: "Cases"

Btw, I am doing all of it in Lightning components

Thanks!

Updates:

**This is the output I see when using,

AllObjectsofOrg = Schema.getGlobalDescribe(); List AllObjs = new List();

    if(!AllObjectsofOrg.isEmpty()) {

        for(String key:AllObjectsofOrg.keySet())
        {
            AllObjs.add(key+'!@#'+AllObjectsofOrg.get(key).getDescribe().getLabelPlural());
        }
    }
    return AllObjs;

Example:

In the list from my code:

Answer 1

You would need to make use of Schema.describeSobjects. This will return you Schema.DescribeSobjectResult. Use the getLabelPlural() method from Schema.DescribeSobjectResult to get the desired output.

Schema.describeSobjects - Describes metadata (field list and object properties) for the specified sObject or array of sObjects.

Schema.DescribeSobjectResult - Contains methods for describing sObjects

getLabelPlural - Returns the object's plural label, which may or may not match the object name.

Below is the code snippet which will give you the desired output:

// get the objects in the org
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();

// remove the unwanted objects like share, history, tag, feed etc
for(String s : gd.keySet()){
  if(s.toLowerCase().contains('history') || s.toLowerCase().contains('tag') 
    || s.toLowerCase().contains('share') || s.toLowerCase().contains('feed')){
     gd.keyset().remove(s);
}   

// remove the faq__kav as it doesnt seem to be supported in describeSObjects. We will add it later once we describe other objects.
gd.keyset().remove('**mynamespace**__faq__kav');

// list to store the object names
List<String> objNames = new List<String>();
objNames.addAll(gd.keyset());

// get the properties of each object like label, plural label, key prefix, isCreatable, isUpdatable etc..
Schema.DescribeSObjectResult[] descResult = Schema.describeSObjects(objNames);

// add the **mynamespace**__faq__kav which we removed in line 12
descResult.add(**mynamespace**__faq__kav.getSObjectType().getDescribe());

// store the plural labels of the result returned above in the list
List<String> pluralLabels = new List<String>();
for(Schema.DescribeSObjectResult res: descResult){
    pluralLabels.add(res.getLabelPlural());        
}
