Go4Fit
Class TGo4FitSlot

class TGo4FitSlot

derived from TGo4FitNamed

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.

Field Detail

fbNeeded

protected Bool_t fbNeeded

Flag, is this object should always be set.

protected Bool_t fbOwned

Ownership flag of object.

protected Int_t fiSaveFlag

Describe saving of object in slot.

protected Int_t fiSaveOwnership

protected Int_t fiSaveSlot

protected TClass* fxClass

Class of object, which should be assigned to slot.

protected TObject* fxObject

Pointer on assigned object.

public TGo4FitSlot()

Default constructor.

public TGo4FitSlot(TNamed* iOwner, TClass* iClass)

Creates TGo4FitSlot object.
This constructor should be called in default constrcutor 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.

public TGo4FitSlot(const char * iName, const char * iTitle, TNamed* iOwner, TClass* iClass, Bool_t iNeeded, TObject* iObject, Bool_t iOwned)

Creates TGo4FitSlot object.
This constrcutor 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.

public virtual synchronized ~TGo4FitSlot()

Destroys TFo4FitSlot object.

public Bool_t CanConnectToSlot(TGo4FitSlot* slot)

Checks, if slot can be connected to other

protected void CheckOwnership()

Sets up ownership relation between object and owner of slot.
If object owned by slot and object drived from TGo4FitNamed class, the owner of slot becames the owned of object.
This gives an ability to combine FullName of TGo4FitNamed object according ownership relation.

public void Clear()

Clear pointer on object in slot.
If object owned, it will be destroyed.

public void ClearConnectionToSlot()

Clear connection to other slot

public TObject* CloneObject(const char * newname)

Clone object in slot and returns pointer on new object.
Name of new object can be optionally specified.

public Bool_t ConnectToSlot(TGo4FitSlot* slot)

Connect this slot to provided slot.
This means, that objects, containing in slot will be also return by GetObject() of current slot.
Class of slots should be compatible
Returns kTRUE, if operation successfull

public TClass* GetClass()

Return pointer on class for desired object.

public const TGo4FitSlot* GetConnectedSlot()

Returns pointer to connected slot or 0, if not connected

public Bool_t GetNeeded()

Return requirement status for slot.
If kTRUE, object should always be sets before any fitting become possible.

public const TObject* GetObject()

Return pointer on assigned object.

public const const char * GetObjectName()

Return name of assigned object.

public Bool_t GetOwned()

Return ownership flag.

public Int_t GetSaveFlag()

Returns save flag.

protected Bool_t HasSaveSettings()

public const Bool_t IsConnectedToSlot()

Returns kTRUE, if slot connected to another slot

public const Bool_t IsEmpty()

Return kTRUE, if no object in slot.

public const Bool_t IsObject()

Return kTRUE, if object assigned to slot.

public const Bool_t IsRequired()

Returns kTRUE, if object required, but not yet set.

public Bool_t IsSuitable(TObject* obj)

Checks, if object class corresponds to class, specified for slot

public virtual const void Print(Option_t* option)

Print information on standard output.

public void SetDefaults(TNamed* iOwner, TClass* iClass)

Set basic fields of slot.
See proper constructor for description. Normally should not be called by user.

public void SetNeeded(Bool_t iNeeded)

Set requirement flag for object.

public Bool_t SetObject(TObject* iObject, Bool_t iOwned, Bool_t CheckClass)

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.

public void SetOwned(Bool_t iOwned)

Explicity sets ownership flag.
Normally should not be called by user.

public void SetSaveFlag(Int_t iSaveFlag)

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.

protected void SetSaveSettings(Int_t save, Int_t own)

protected Bool_t WillBeSaved()
