## Member Function Documentation

IAlgTool::DeclareInterfaceID | ( | IAlgTool | ,
|  | 3 | ,
|  | 0 |  |
| ) |  |  |

InterfaceID.

virtual const std::string& IAlgTool::type | ( |  | ) | const`[pure virtual]`

The type of an AlgTool, meaning the concrete AlgTool class.

virtual const IInterface* IAlgTool::parent | ( |  | ) | const`[pure virtual]`

The parent of the concrete AlgTool.

It can be an Algorithm or a Service. A common AlgTool has the ToolSvc as parent.

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

Configuration (from OFFLINE to CONFIGURED).

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

Initialization (from CONFIGURED to INITIALIZED).

Implemented in SequencerTimerTool, EqSolver, FuncMinimum, and DataStreamTool.

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

Start (from INITIALIZED to RUNNING).

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

Stop (from RUNNING to INITIALIZED).

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

Finalize (from INITIALIZED to CONFIGURED).

Implemented in SequencerTimerTool, EqSolver, FuncMinimum, GslErrorCount, and DataStreamTool.

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

Initialization (from CONFIGURED to OFFLINE).

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

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

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

Initialization (from RUNNING to RUNNING, via INITIALIZED).

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

Get the current state.

virtual StatusCode IAlgTool::sysInitialize | ( |  | ) | `[pure virtual]`

Initialization of the Tool.

This method is called typically by the ToolSvc. It allows to complete the initialization that could not be done with a simply a constructor.

virtual StatusCode IAlgTool::sysStart | ( |  | ) | `[pure virtual]`

Initialization of the Tool.

This method is called typically by the ToolSvc. It allows to complete the initialization that could not be done with a simply a constructor.

virtual StatusCode IAlgTool::sysStop | ( |  | ) | `[pure virtual]`

Initialization of the Tool.

This method is called typically by the ToolSvc. It allows to complete the initialization that could not be done with a simply a constructor.

virtual StatusCode IAlgTool::sysFinalize | ( |  | ) | `[pure virtual]`

Finalization of the Tool.

This method is called typically by the ToolSvc. For completeless this method is called before the tool is destructed.

virtual StatusCode IAlgTool::sysReinitialize | ( |  | ) | `[pure virtual]`

Initialization of the Tool.

This method is called typically by the ToolSvc. It allows to complete the initialization that could not be done with a simply a constructor.

virtual StatusCode IAlgTool::sysRestart | ( |  | ) | `[pure virtual]`

Initialization of the Tool.

This method is called typically by the ToolSvc. It allows to complete the initialization that could not be done with a simply a constructor.

virtual unsigned long IAlgTool::refCount | ( |  | ) | const`[pure virtual]`

Current number of reference counts.

Avoids having to call addRef() + release() to get current refCount.

Implements IInterface.
