state_machine_db package¶

Submodules¶

This module implements a state machine that waits for flags to jump from state to state until it is finished

class state_machine_db.state_machine.StateMachine(sm_database_path, activity_id)¶

Bases: threading.Thread

Implements a totally configurable state machine

Parameters:	sm_database_path (`str`) – path to the sqlite database activity_id (`str`) – identifier for the current state machine instance

static check_if_thread_alive(activity_id)¶

Checks if there is a thread related to activity_id

Parameters:	activity_id (`str`) – identifier for the current state machine instance
Returns:	True if there is a thread, False otherwise

static get_sm_alive_threads()¶

Get info about all running threads related to state machine

Returns:	A dictionary containing the name of each running thread and its thread object

get_updated_states()¶: This method must be implemented in the child class and return, after an update in the update_flag, a list of updated states

run()¶: Initiates the thread that effectivelly implements the state machine. A change of state must be sinalized by a flag (update, must be True) The final state must be sinalized by a flag (is_finished, must be True)
