Introspection Overview

get_info() returns a StateMachineInfo Pydantic model describing configured states and transitions.

Top-Level Model

StateMachineInfo includes:

• states: list[StateInfo]
• state_type: type
• trigger_type: type
• initial_state

StateInfo

Each state includes:

• underlying state value
• entry/exit/activate/deactivate action metadata
• substate relationships and superstate value
• fixed transitions
• internal transitions
• ignored triggers
• dynamic transitions
• initial transition target (if configured)

Example

info = sm.get_info()

for state in info.states:
    print(state.underlying_state)
    for t in state.fixed_transitions:
        print(" ", t.trigger.underlying_trigger, "->", t.destination_state)

Trigger Metadata

If you configure trigger parameter metadata with set_trigger_parameters(...), it appears in TriggerInfo.parameter_types inside introspection output.
