Member Function Documentation

configure()

virtual StatusCode IStateful::configure ( )

pure virtual

Configuration (from OFFLINE to CONFIGURED).

DeclareInterfaceID()

IStateful::DeclareInterfaceID	(	IStateful	,
		1	,
		0	)

InterfaceID.

finalize()

virtual StatusCode IStateful::finalize ( )

pure virtual

Finalize (from INITIALIZED to CONFIGURED).

FSMState()

virtual Gaudi::StateMachine::State IStateful::FSMState ( ) const

pure virtual

Get the current state.

initialize()

virtual StatusCode IStateful::initialize ( )

pure virtual

Initialization (from CONFIGURED to INITIALIZED).

reinitialize()

virtual StatusCode IStateful::reinitialize ( )

pure virtual

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

restart()

virtual StatusCode IStateful::restart ( )

pure virtual

Initialization (from RUNNING to RUNNING, via INITIALIZED).

start()

virtual StatusCode IStateful::start ( )

pure virtual

Start (from INITIALIZED to RUNNING).

stop()

virtual StatusCode IStateful::stop ( )

pure virtual

Stop (from RUNNING to INITIALIZED).

targetFSMState()

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().

terminate()

virtual StatusCode IStateful::terminate ( )

pure virtual

Initialization (from CONFIGURED to OFFLINE).
