In Salesforce Apex, getQuiddity() returns the Quiddity value of the current Request object. It can be used to find the Salesforce Apex current running context.

Sample Apex Class:

public class Utility {
    
    public static void checkExecution() {
        
        Request objReq = Request.getCurrent();
        
        switch on objReq.getQuiddity() {
