Member Typedef Documentation

◆ StoreType

template<typename T>

Definition at line 128 of file SysReadHandle.h.

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.

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 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.

◆ addDecorationDependency()

template<typename T>

virtual StatusCode CP::SysReadHandle< T >::addDecorationDependency	(	const ISystematicsSvc &	svc,
		const std::string &	decoName,
		bool	decoWrite )

overrideprivatevirtual

add dependency information for the given decoration

Implements CP::ISysObjectHandleBase.

◆ empty()

template<typename T>

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

overridevirtualnoexcept

whether we have a name configured

Implements CP::ISysHandleBase.

◆ fillSystematics()

template<typename T>

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

overrideprivatevirtual

register and cache the systematics

Implements CP::ISysHandleBase.

◆ getInputAffecting()

template<typename T>

virtual CP::SystematicSet CP::SysReadHandle< 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::SysReadHandle< T >::getName ( const CP::SystematicSet & sys ) const

get the name we retrieve from the event store

◆ getNamePattern()

template<typename T>

virtual std::string CP::SysReadHandle< T >::getNamePattern ( ) const

overridevirtual

get the name pattern before substitution

Implements CP::ISysObjectHandleBase.

◆ initialize() [1/2]

template<typename T>

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

initialize this handle

◆ 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

check if the object is available Note that this should only be used in special use cases and may be removed in the future.

◆ 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::SysReadHandle< T >::operator bool ( ) const

explicitnoexcept

!empty()

◆ retrieve()

template<typename T>

::StatusCode CP::SysReadHandle< T >::retrieve	(	const T *&	object,
		const CP::SystematicSet &	sys ) 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 150 of file SysReadHandle.h.

◆ m_evtStore

template<typename T>

StoreType* CP::SysReadHandle< T >::m_evtStore = nullptr

private

the event store we use

Definition at line 132 of file SysReadHandle.h.

◆ m_evtStoreGetter

template<typename T>

std::function<StoreType*()> CP::SysReadHandle< T >::m_evtStoreGetter

private

the function to retrieve the event store

This is an std::function to allow the parent to be either a tool or an algorithm. Though we are not really supporting tools as parents when using SysListHandle, so in principle this could be replaced with a pointer to the algorithm instead.

Definition at line 142 of file SysReadHandle.h.

◆ m_inputName

template<typename T>

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

private

the input name we use

Definition at line 118 of file SysReadHandle.h.

◆ m_inputNameCache

template<typename T>

std::unordered_map<CP::SystematicSet,std::string> CP::SysReadHandle< T >::m_inputNameCache

private

the cache of names we use

Definition at line 122 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.
