Member Function Documentation

const InterfaceID & ComponentManager::componentBaseInterface ( ) const

override

Basic interface id of the managed components.

Definition at line 19 of file ComponentManager.cpp.

{ return m_basicInterfaceId; }

StatusCode ComponentManager::configure ( )

inlineoverride

Configuration (from OFFLINE to CONFIGURED).

Definition at line 37 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

StatusCode ComponentManager::finalize ( )

inlineoverride

Finalize (from INITIALIZED to CONFIGURED).

Definition at line 49 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

Gaudi::StateMachine::State ComponentManager::FSMState ( ) const

inlineoverride

Get the current state.

Definition at line 61 of file ComponentManager.h.

{ return m_stateful->FSMState(); }

StatusCode ComponentManager::initialize ( )

inlineoverride

Initialization (from CONFIGURED to INITIALIZED).

Definition at line 40 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

StatusCode ComponentManager::queryInterface ( const InterfaceID &  iid, void **  pinterface  )

override

Specialized queryInterface implementation.

If an interface is not fount in the implemented ones, we fall back on the owner.

Definition at line 23 of file ComponentManager.cpp.

{
  // try local interfaces
  StatusCode sc = base_class::queryInterface( iid, pinterface );
  // fall back on the owner, if local interface didn't match...
  return sc.isSuccess() ? sc : m_application->queryInterface( iid, pinterface );
}

StatusCode ComponentManager::reinitialize ( )

inlineoverride

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

Definition at line 55 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

StatusCode ComponentManager::restart ( )

inlineoverride

Initialization (from RUNNING to RUNNING, via INITIALIZED).

Definition at line 58 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

SmartIF<ISvcLocator>& ComponentManager::serviceLocator ( ) const

inlineoverride

Definition at line 30 of file ComponentManager.h.

  {
    if ( !m_svcLocator ) m_svcLocator = m_application;
    return m_svcLocator;
  }

StatusCode ComponentManager::start ( )

inlineoverride

Start (from INITIALIZED to RUNNING).

Definition at line 43 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

StatusCode ComponentManager::stop ( )

inlineoverride

Stop (from RUNNING to INITIALIZED).

Definition at line 46 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }

Gaudi::StateMachine::State ComponentManager::targetFSMState ( ) const

inlineoverride

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().

Definition at line 65 of file ComponentManager.h.

{ return m_stateful->targetFSMState(); }

StatusCode ComponentManager::terminate ( )

inlineoverride

Initialization (from CONFIGURED to OFFLINE).

Definition at line 52 of file ComponentManager.h.

{ return StatusCode::SUCCESS; }
