Detailed Description

The central user class to manipulate any global constant in any DB object Used to retrieve global parameters from database and access the for update.

Finally all objects can be released for storing in the DB. NOTE the objects are not constructed (an thus quite some memory is saved) until you access them. But the monitoring of changes in DB starts since addDBObj<...>() TODO correct constness to not construct on listGlobalParams()

Constructor & Destructor Documentation

◆ GlobalParamVector()

GlobalParamVector ( const std::vector< std::string > & components = {} )

explicit

Constructor.

Parameters

components vector of string with DB objects default names in the global vector If empty, any component is included by default.

Definition at line 76 of file GlobalParam.cc.

Member Function Documentation

◆ addDBObj()

void addDBObj ( std::shared_ptr< IGlobalParamInterface > interface = {} )

inline

Add a DB object to the vector, optionally with interface.

Parameters

interface shared pointer to an interface added only if this DB object is listed in 'components' or 'components' not specified Does nothing if DB object type already added

Definition at line 371 of file GlobalParam.h.

◆ getDBObj()

DBObjType* getDBObj ( )

inline

Get the raw pointer toa stored object WARNING: Use with caution, returns nullptr if object not registered (e.g.

disabled via 'components')

Definition at line 449 of file GlobalParam.h.

◆ getGlobalParam()

double getGlobalParam	(	unsigned short	uniqueID,
		unsigned short	element,
		unsigned short	param
	)

Get parameter value.

Parameters

uniqueID	uinique id of the DB object
element	id of the element with params inside DB object
param	id of the parameter of the element

Definition at line 96 of file GlobalParam.cc.

◆ getGlobalParamSet()

GlobalParamSetAccess& getGlobalParamSet ( )

inline

Get reference to the underlying DB object container You should check the container.

Returns: GlobalParamSet<DBObjType> or GlobalParamSet<EmptyGlobalParamSet> if DBObjType not in global vector (e.g. because disabled via 'components')

Definition at line 462 of file GlobalParam.h.

◆ hasBeenChangedInDB()

bool hasBeenChangedInDB	(	const std::set< unsigned short > &	subset,
		bool	resetChangedState = `true`
	)

inline

Has any DB object in vector changed from last call to this function.

Parameters

subset	set of unique ids of objects we are interested
resetChangedState	should this call result in hasBeenChangedInDB=true?

Definition at line 387 of file GlobalParam.h.

◆ releaseObjects()

std::vector< TObject * > releaseObjects ( bool onlyConstructed = true )

Get the vector of raw pointers to DB objects Caller takes the ownership of the objects and has to delete them Use for passing the objects to store in DB (not deleted after GlobalParamVector goes out of scope)

Parameters

onlyConstructed if true, only returns objects which have been actually constructed Objects are not constructed until accessed or copied from DB (or constructed explicitly)

Definition at line 117 of file GlobalParam.cc.

◆ setGlobalParam()

void setGlobalParam	(	double	value,
		unsigned short	uniqueID,
		unsigned short	element,
		unsigned short	param
	)

Set param value.

Parameters

value	value to set
uniqueID	uinique id of the DB object
element	id of the element with params inside DB object
param	id of the parameter of the element

Definition at line 85 of file GlobalParam.cc.

◆ updateGlobalParam()

void updateGlobalParam	(	double	difference,
		unsigned short	uniqueID,
		unsigned short	element,
		unsigned short	param
	)

Add 'difference' to param value.

Parameters

difference	value to add to current value
uniqueID	uinique id of the DB object
element	id of the element with params inside DB object
param	id of the parameter of the element

Definition at line 78 of file GlobalParam.cc.
