Constructor & Destructor Documentation

◆ SysReadHandle() [1/2]

template<typename T>

template<typename T2>

CP::SysReadHandle< T >::SysReadHandle	(	T2 *	owner,
		const std::string &	propertyName,
		const std::string &	propertyValue,
		const std::string &	propertyDescription )

Standard constructor.

Public Members

Parameters

owner	Used to declare the property and for its messaging
propertyName	The name of the property to declare
propertyValue	The default value for the property
propertyDescription	The description of the property

This version of the constructor declares a property on the parent object and should usually be preferred when the container to be read should be configurable

◆ SysReadHandle() [2/2]

template<typename T>

template<typename T2>

CP::SysReadHandle< T >::SysReadHandle	(	const std::string &	inputName,
		T2 *	owner )

Direct constructor which doesn't declare a property.

◆ initialize() [2/2]

template<typename T>

StatusCode CP::SysReadHandle< T >::initialize	(	SysListHandle &	sysListHandle,
		SG::AllowEmptyEnum	)

◆ isValid()

template<typename T>

bool CP::SysReadHandle< T >::isValid	(	const CP::SystematicSet &	sys,
		const EventContext &	ctx = Gaudi::Hive::currentContext() ) const

◆ msg() [1/2]

MsgStream & asg::AsgMessagingForward::msg ( ) const

inherited

The standard message stream.

Returns: A reference to the default message stream of this object.

Definition at line 24 of file AsgMessagingForward.cxx.

  {
    return m_msg();
  }

◆ msg() [2/2]

MsgStream & asg::AsgMessagingForward::msg ( const MSG::Level lvl ) const

inherited

The standard message stream.

Parameters

lvl	The message level to set the stream to

Returns: A reference to the default message stream, set to level "lvl"

Definition at line 29 of file AsgMessagingForward.cxx.

  {
    MsgStream& msg = m_msg ();
    msg << lvl;
    return msg;
  }

◆ msgLvl()

bool asg::AsgMessagingForward::msgLvl ( const MSG::Level lvl ) const

inherited

Test the output level of the object.

Parameters

lvl	The message level to test against

Returns: boolean Indicting if messages at given level will be printed; true If messages at level "lvl" will be printed

Definition at line 11 of file AsgMessagingForward.cxx.

  {
    MsgStream& msg = m_msg();
    if (msg.level() <= lvl)
    {
      msg << lvl;
      return true;

explicitnoexcept

!empty()

◆ retrieve()

template<typename T>

::StatusCode CP::SysReadHandle< T >::retrieve	(	const T *&	object,
		const CP::SystematicSet &	sys,
		const EventContext &	ctx = Gaudi::Hive::currentContext() ) const

retrieve the object for the given name

Member Data Documentation

◆ m_addAlgDependency

template<typename T>

std::function<void(const DataObjID&, Gaudi::DataHandle::Mode)> CP::SysReadHandle< T >::m_addAlgDependency

private

a function to add a data dependency to the parent algorithm

This wraps the owner's addDependency call and is used by addDecorationDependency to register MT dependencies.

Definition at line 130 of file SysReadHandle.h.

◆ m_inputName

template<typename T>

std::string CP::SysReadHandle< T >::m_inputName

private

the input name we use

Private Members

Definition at line 111 of file SysReadHandle.h.

◆ m_msg

std::function<MsgStream& ()> asg::AsgMessagingForward::m_msg

privateinherited

the message stream we use

This used to be a simple pointer to the MsgStream itself, but in AthenaMT the actual object used is local to the thread. So instead of pointing to it directly we are now using a function to look it up, which will get the thread-local object.

Definition at line 77 of file AsgMessagingForward.h.

◆ m_sysData

template<typename T>

std::unordered_map<CP::SystematicSet,SysData> CP::SysReadHandle< T >::m_sysData

private
