How to dynamically determine Calling Context using Apex in Salesforce?

Hi All ,

we are using the multiple feature and Context (type) as per our requirement while writing Apex code.

Sample are:-

• Batch
• @future 
• Queueable 
• Schedulable 
• Trigger 
• Visualforce 
• Apex REST 

so we can identify these context item in Apex code  as give way:-

•  Batch - System.isBatch()
• @future - System.isFuture()
• Queueable - System.isQueueable()
• Schedulable - System.isScheduled()
• Trigger - Trigger.isExecuting
• Visualforce - ApexPages.currentPage() != null
• Apex REST - RestContext.request != null
