## Member Function Documentation

virtual StatusCode IStateful::configure | ( | ) | `[pure virtual]`

Configuration (from OFFLINE to CONFIGURED).

Implemented in ComponentManager.

IStateful::DeclareInterfaceID | ( | IStateful | ,
|  | 1 | ,
|  | 0 |
| ) |  |

InterfaceID.

virtual StatusCode IStateful::finalize | ( | ) | `[pure virtual]`

Finalize (from INITIALIZED to CONFIGURED).

Implemented in AlgorithmManager, ServiceManager, and ComponentManager.

virtual Gaudi::StateMachine::State IStateful::FSMState | ( | ) | const`[pure virtual]`

Get the current state.

Implemented in ComponentManager.

virtual StatusCode IStateful::initialize | ( | ) | `[pure virtual]`

Initialization (from CONFIGURED to INITIALIZED).

Implemented in AlgorithmManager, ServiceManager, and ComponentManager.

virtual StatusCode IStateful::reinitialize | ( | ) | `[pure virtual]`

Initialization (from INITIALIZED or RUNNING to INITIALIZED, via CONFIGURED).

Implemented in AlgorithmManager, ServiceManager, and ComponentManager.

virtual StatusCode IStateful::restart | ( | ) | `[pure virtual]`

Initialization (from RUNNING to RUNNING, via INITIALIZED).

Implemented in AlgorithmManager, ServiceManager, and ComponentManager.

virtual StatusCode IStateful::start | ( | ) | `[pure virtual]`

Start (from INITIALIZED to RUNNING).

Implemented in AlgorithmManager, ServiceManager, and ComponentManager.

virtual StatusCode IStateful::stop | ( | ) | `[pure virtual]`

Stop (from RUNNING to INITIALIZED).

Implemented in AlgorithmManager, ServiceManager, and ComponentManager.

virtual Gaudi::StateMachine::State IStateful::targetFSMState | ( | ) | const`[pure virtual]`

When we are in the middle of a transition, get the state where the transition is leading us.

Otherwise it returns the same state as state().

Implemented in ComponentManager.

virtual StatusCode IStateful::terminate | ( | ) | `[pure virtual]`

Initialization (from CONFIGURED to OFFLINE).

Implemented in ComponentManager.
