Detailed Description

template<typename T>
class CP::SysReadDecorHandle< T >

a data handle for reading systematics varied input data

Definition at line 32 of file SysReadDecorHandle.h.

Constructor & Destructor Documentation

◆ SysReadDecorHandle() [1/2]

template<typename T>

template<typename T2>

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

Standard constructor.

Template Parameters

T2	The type of the owner

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 decoration to be read should be configurable

◆ SysReadDecorHandle() [2/2]

template<typename T>

template<typename T2>

CP::SysReadDecorHandle< T >::SysReadDecorHandle	(	const std::string &	decorName,
		T2 *	owner )

Construct the handle directly without declaring a property.

Member Function Documentation

◆ empty()

template<typename T>

virtual bool CP::SysReadDecorHandle< T >::empty ( ) const

overridevirtualnoexcept

whether we have a name configured

Implements CP::ISysHandleBase.

◆ fillSystematics()

template<typename T>

virtual StatusCode CP::SysReadDecorHandle< T >::fillSystematics	(	const ISystematicsSvc &	svc,
		const CP::SystematicSet &	fullAffecting,
		const std::vector< CP::SystematicSet > &	sysList )

overrideprivatevirtual

register and cache the systematics

Implements CP::ISysHandleBase.

◆ get()

template<typename T>

const T & CP::SysReadDecorHandle< T >::get	(	const SG::AuxElement &	object,
		const CP::SystematicSet &	sys ) const

retrieve the object decoration for the given systematic

◆ getData()

template<typename T>

const auto & CP::SysReadDecorHandle< T >::getData ( const CP::SystematicSet & sys ) const

private

get the data for the given systematics

◆ getInputAffecting()

template<typename T>

virtual CP::SystematicSet CP::SysReadDecorHandle< T >::getInputAffecting ( const ISystematicsSvc & svc ) const

overrideprivatevirtual

get the affecting systematics if this is an input handle

This returns the empty set if this is either not an input handle, or if the input handle is not affected by systematics.

Implements CP::ISysHandleBase.

◆ getName()

template<typename T>

const std::string & CP::SysReadDecorHandle< T >::getName ( const CP::SystematicSet & sys ) const

get the name we retrieve from the event store

◆ initialize() [1/2]

template<typename T>

StatusCode CP::SysReadDecorHandle< T >::initialize	(	SysListHandle &	sysListHandle,
		ISysObjectHandleBase &	objectHandle )

initialize this handle

◆ initialize() [2/2]

template<typename T>

StatusCode CP::SysReadDecorHandle< T >::initialize	(	SysListHandle &	sysListHandle,
		ISysObjectHandleBase &	objectHandle,
		SG::AllowEmptyEnum	)

◆ 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;
    } else
    {
      return false;
    }
  }

◆ operator bool()

template<typename T>

CP::SysReadDecorHandle< T >::operator bool ( ) const

explicitnoexcept

!empty()

Member Data Documentation

◆ m_dataCache

template<typename T>

std::unordered_map<CP::SystematicSet,std::tuple<std::string,SG::ConstAccessor<T> > > CP::SysReadDecorHandle< T >::m_dataCache

private

the cache of names we use

Definition at line 119 of file SysReadDecorHandle.h.

◆ m_decorName

template<typename T>

std::string CP::SysReadDecorHandle< T >::m_decorName

private

the input name we use

Definition at line 111 of file SysReadDecorHandle.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_objectHandle

template<typename T>

ISysObjectHandleBase* CP::SysReadDecorHandle< T >::m_objectHandle {nullptr}

private

the object handle we use

Definition at line 115 of file SysReadDecorHandle.h.

115{nullptr};
