gemseo.core.execution_status module

Execution status of processes.

class ExecutionStatus(process_name)

Bases: Serializable

Execution status of a process.

The status aims at monitoring a process and give the user a simplified view on the state of the processes.

The possible statuses are defined in Status. The status rules are: - the initial status is DONE, - the status RUNNING or LINEARIZING can only be set when the current one is

DONE,

• the status DONE can only be set when the current one is RUNNING.

Helper methods should be used to handle the statuses when running or linearizing a process: run() and linearize().

Observers can be attached and are notified when the value of the status is changed. The observers are not restored after pickling.

Initialize self. See help(type(self)) for accurate signature.

Parameters:

process_name (str) -- The name of the process.
