Detailed Description

Result class to help monitor status of jobs submitted by Local backend.

Definition at line 949 of file backends.py.

Constructor & Destructor Documentation

__init__()

__init__	(		self,
			job,
			result )

Pass in the job object and the multiprocessing result to allow the result to do monitoring and perform
post processing of the job.

get_exit_code_from_file()

get_exit_code_from_file ( self )

inherited

Read the exit code file to discover the exit status of the job command. Useful fallback if the job is no longer
known to the job database (batch system purged it for example). Since some backends may take time to download
the output files of the job back to the working directory we use a time limit on how long to wait.
