Constructor & Destructor Documentation

FirstAssociationTool()

D3PD::FirstAssociationTool::FirstAssociationTool	(	const std::string &	type,
		const std::string &	name,
		const IInterface *	parent )

Standard Gaudi tool constructor.

Parameters

type	The name of the tool type.
name	The tool name.
parent	The tool's Gaudi parent.

Definition at line 28 of file FirstAssociationTool.cxx.

  : base_class (type, name, parent),
    m_associator (this)
{
  declareProperty ("Associator", m_associator,
                   "The IMultiAssociationTool instance to wrap.");
}

Member Function Documentation

book()

StatusCode D3PD::FirstAssociationTool::book ( )

overridevirtual

Declare tuple variables.

This is called at the start of the first event.

Definition at line 71 of file FirstAssociationTool.cxx.

{
  CHECK( m_associator->book() );
  return StatusCode::SUCCESS;
}

configureD3PD()

StatusCode D3PD::FirstAssociationTool::configureD3PD ( IAddVariable * tree, const std::type_info & ti )

overridevirtual

Configure during initialization: type-check.

Parameters

tree	Our parent for tuple making.
ti	Gives the type of the object being passed to resetUntyped.

configureD3PD should check that the type of the object coming as input is compatible with what it expects, and raise an error otherwise.

Definition at line 58 of file FirstAssociationTool.cxx.

{
  CHECK( m_associator->configureD3PD (tree, ti) );
  return StatusCode::SUCCESS;
}

getUntyped()

const void * D3PD::FirstAssociationTool::getUntyped ( const void * p )

overridevirtual

Return the target object.

Parameters

p	The source object for the association.

Return the target of the association, or 0. Should be of the type given by typeinfo.

Definition at line 95 of file FirstAssociationTool.cxx.

{
  StatusCode sc = m_associator->resetUntyped (p);
  if (sc.isFailure())
    return 0;
  return m_associator->nextUntyped();
}

initialize()

StatusCode D3PD::FirstAssociationTool::initialize ( )

overridevirtual

Standard Gaudi initialize method.

Definition at line 42 of file FirstAssociationTool.cxx.

{
  CHECK( AthAlgTool::initialize() );
  CHECK( m_associator.retrieve() );
  return StatusCode::SUCCESS;
}

releaseObjectUntyped()

void D3PD::FirstAssociationTool::releaseObjectUntyped ( const void * p )

overridevirtual

Release an object retrieved from the association.

Parameters

p	The object to release.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the association dynamically allocated the object which it returned, this gives it a chance to free it.

Definition at line 113 of file FirstAssociationTool.cxx.

{
  m_associator->releaseElementUntyped (p);
}

typeinfo()

const std::type_info & D3PD::FirstAssociationTool::typeinfo ( ) const

overridevirtual

Return the type of object retrieved by this tool.

Definition at line 81 of file FirstAssociationTool.cxx.

{
  return m_associator->elementTypeinfo();
 
}
