Triggers on Files

There are two possible triggers that can be set that depend on a file's timestamp:

• Run Trigger: when this trigger is set, and the timestamp of the file changes, the downcone of the file is automatically run.
• Stop Trigger: when this trigger is set, and the timestamp of the file changes, all running jobs in the downcone of the file are automatically stopped.

The simplest way to set triggers in FDL is to use the options -trigger,run and -trigger,stop in the I call that registers the file as input.

# Example of setting a trigger flag in FDL
J vw cp aa bb
I -trigger,run aa     

Triggers on a file can be set using the vtk API.

# Example of manipulation of both trigger flags using the VTK API.
set placeId [vtk_place_find "FILE" "aa"]
vtk_place_get $placeId placeInfo

set placeInfo(trigger,run)  1
set placeInfo(trigger,stop) 1

vtk_place_set $placeId placeInfo
