Reading attributes

[Jim Wagoner <vt...@gmail.com>]

Would it be worth adding to check making sure required attributes are on a
flow file when onTrigger is called? I find myself putting all the
attributes I define in 'ReadAttributes" in a List and then verifying they
exist on the flow file as one of the first steps of my onTrigger call (and
of course failing the flow if something is missing). Would it be worth it
to bake this type of check in?
