Detailed Description

Object for managing pointers on specific objects.

General purpose of this object - store pointer on any kind of object (derived from TObject) with/without ownership and provide a general interface to set/get and store/restore this object. Slot always belong to another object (has owner). Slot always knows, what kind of object should be assigned to it (via Class property). Slots may be distributed in different places of fitter: in data object (typically for assigning data like TH1, TGraph or other), sometimes in model object (like in TGo4FitModelFromData in slot TGo4FitData object should be placed to provide bins for model component) or complex hierarchy of these objects possible. Fitter has a method to collect a list of all slots from all possible places. Once all slots are collected, fitter know, how many and what kind of objects should be (or can be) assigned to fitter before start fitting. Fitter (see TGo4FitterAbstract description) has a set of function for manipulating with objects in slots.

Constructor & Destructor Documentation

TGo4FitSlot::TGo4FitSlot ( )

Default constructor.

Definition at line 22 of file TGo4FitSlot.cxx.

TGo4FitSlot::TGo4FitSlot	(	TNamed *	iOwner,
		TClass *	iClass
	)

Creates TGo4FitSlot object.

This constructor should be called in default constructor of object, where slot situated. Constructor only sets owner of slot, desired class of object and if this object should be always owned. The rest values (name, title, object and so on) should be restored by streamer, which typically calls default constructor.

Definition at line 34 of file TGo4FitSlot.cxx.

References TGo4FitNamed::SetOwner().

TGo4FitSlot::TGo4FitSlot	(	const char *	iName,
		const char *	iTitle,
		TNamed *	iOwner,
		TClass *	iClass,
		Bool_t	iNeeded = `kFALSE`,
		TObject *	iObject = `0`,
		Bool_t	iOwned = `kFALSE`
	)

Creates TGo4FitSlot object.

This constructor should be placed in normal constructor of object, where slot is situated. Constructor sets name and title of slot, owner of slot, desired class of object and if this object always should be owned. Optionally, requirements of object (is it always needed or not, default - not), pointer on object and ownership flag can be specified.

See proper constructor for description. Normally should not be called by user.

void TGo4FitSlot::SetSaveFlag ( Int_t iSaveFlag ) [inline]

Set save flag for saving of object in slot, when slot stored to streamer: 0 - object will be saved if it owned, 1 - object always will be saved 2 - object never will be saved.

Bool_t TGo4FitSlot::SetObject	(	TObject *	iObject,
		Bool_t	iOwned = `kFALSE`,
		Bool_t	CheckClass = `kTRUE`
	)

Sets object to slot.

First, if before another object was set to slot with ownership flag, it will be destroyd. Then, if object should always be owned by slot, but object is assigning without ownersip, it will be cloned and clone will be assigned with ownership flag. if CheckClass==kTRUE (default), slot will refuse unsuitable object class. If object owned by slot, it always be destroyed by slot.
