Detailed Description

StateMachine

This is a finite state machine smach container. Note that though this is
a state machine, it also implements the L{smach.State}
interface, so these can be composed hierarchically, if such a pattern is
desired.

States are added to the state machine as 3-tuple specifications:
 - label
 - state instance
 - transitions

The label is a string, the state instance is any class that implements the
L{smach.State} interface, and transitions is a dictionary mapping strings onto
strings which represent the transitions out of this new state. Transitions
can take one of three forms:
 - OUTCOME -> STATE_LABEL
 - OUTCOME -> None (or unspecified)
 - OUTCOME -> SM_OUTCOME

Member Function Documentation

def src.airbus_ssm_core.ssm_state_machine.ssmMainStateMachine._request_preempt_cb	(		self,
			msg
	)		[private]

Callback empty message for propagate preempt
to currently active state.

Reimplemented from src.airbus_ssm_core.ssm_state_machine.ssmStateMachine.

Definition at line 361 of file ssm_state_machine.py.

def src.airbus_ssm_core.ssm_state_machine.ssmMainStateMachine.execute	(		self,
			parent_ud = smach.UserData()
	)

Run the state machine on entry to this state.
This will set the "closed" flag and spin up the execute thread. Once
this flag has been set, it will prevent more states from being added to
the state machine.
