Determine the execution context in apex

 

 

 

The Quiddity Enum stands out as a highly valuable but often overlooked feature, offering one of the most effective means to grasp the context of Apex execution. Leveraging Quiddity allows us to discern whether an Apex method is invoked from Lightning Web Components (LWC), Aura, or an Anonymous context. Explore the comprehensive documentation linked below to discover the full range of contexts supported by Quiddity.

Below is the Example of Quiddity.

public List<Account> getAccountsWithQuiddityGuard(){
      List<Account> accounts = new List<Account>();
      
      public static List<Quiddity> allowedQuiddities = new List<Quiddity>{
             Quiddity.QUEUEABLE,
             Quiddity.BATCH_APEX,
             Quiddity.RUNTEST_ASYNC,
             Quiddity.RUNTEST_SYNC
      };
      Quiddity q = System.Request.getCurrent().getQuiddity();    
      
      if(allowedQuiddities.contains(q)){
          accounts = [Select ID from Account];
      } else{
          accounts = [Select Id from Account with SECURITY_ENFORCED];
      }
      
      return accounts;
  }

 

The Request class is under System namespace in apex. Request.getCurrent().getQuiddity() type is Quiddity — a enum which can hold the following values

🔹ANONYMOUS
🔹 AURA
🔹 BATCH_APEX
🔹 BATCH_CHUNK_PARALLEL
🔹 BATCH_CHUNK_SERIAL
🔹 BULK_API
🔹 FUNCTION_CALLBACK
🔹 FUTURE
🔹 QUEUEABLE
🔹 REST
🔹 SCHEDULED
🔹 SOAP
🔹 SYNCHRONOUS
🔹 VF
