How can my code tell if it's inside a Queueable context?

Question

To go with the new System.Queueable interface, I'm looking for the analogy of:

• System.isBatch()
• System.isFuture()
• System.isScheduled()

Is there a System.isQueued() or something?

Answer 1

Spring '16 brings us a new method:

System.isQueueable() which takes care of this requirement.

As of Spring '16, isBatch() does NOT return true from inside Queueable implementation.

I think that better is option is use this query, to veryfy if your class is in the queue

SELECT Id, ApexClassId from AsyncApexJob WHERE JobType = 'Queueable' AND Status = 'Queued' AND ApexClassId in (SELECT Id FROM ApexClass WHERE NAME = 'Imp')
