Detailed Description

Handler for user objects attached to the track selection result ptr.

Handling the lifetime of the object attached to the AliEmcalTrackSelResultPtr using reference counting technique. Pointer instances created from the current pointer using the copy constructor or assignment operator connect to the common storage and disconnect once they are constructed. The last instance connected to a storage deletes it.

This class is foreseen to be used only from within AliEmcalTrackSelResultPtr.

Constructor & Destructor Documentation

AliEmcalTrackSelResultUserPtr::AliEmcalTrackSelResultUserPtr

(

)

Dummy constructor.

Not handling object

Definition at line 183 of file AliEmcalTrackSelResultPtr.cxx.

AliEmcalTrackSelResultUserPtr::AliEmcalTrackSelResultUserPtr

(

TObject *

o

)

Main constructor setting the data.

Allocating the storage for the data hanlding and initializes the reference count

Parameters

o	Object to be handled by the user pointer

Definition at line 190 of file AliEmcalTrackSelResultPtr.cxx.

AliEmcalTrackSelResultUserPtr::AliEmcalTrackSelResultUserPtr

(

const AliEmcalTrackSelResultUserPtr &

ref

)

Copy constructor.

Creating a new pointer instance connected to the same storage

Parameters

ref	Reference for the copy

Definition at line 197 of file AliEmcalTrackSelResultPtr.cxx.

AliEmcalTrackSelResultUserPtr::AliEmcalTrackSelResultUserPtr

(

AliEmcalTrackSelResultUserPtr &&

ref

)

Move constructor.

Only transferring the storage, has no consequence on the reference count

Parameters

ref	Object to be moved

Definition at line 207 of file AliEmcalTrackSelResultPtr.cxx.

AliEmcalTrackSelResultUserPtr::~AliEmcalTrackSelResultUserPtr ( )

virtual

Destructor.

Disconnects pointer instance from the common storage. If it is the last pointer instance conneted to the storage deletes the storage as well.

Member Function Documentation

TObject* PWG::EMCAL::AliEmcalTrackSelResultUserPtr::GetData ( ) const

inline

Get the object handled by the storage.

Returns

User object handled by the pointer if storage exists, nullptr otherwise

Definition at line 212 of file AliEmcalTrackSelResultPtr.h.

AliEmcalTrackSelResultUserPtr & AliEmcalTrackSelResultUserPtr::operator=

(

const AliEmcalTrackSelResultUserPtr &

ref

)

Assignment operator.

Connecting pointer instance to the storage connected to by ref. In case the pointer handles a storage itself disconnects from the storage

Parameters

ref	Reference for assignment

Returns

Pointer instance after assignment

Definition at line 218 of file AliEmcalTrackSelResultPtr.cxx.

AliEmcalTrackSelResultUserPtr & AliEmcalTrackSelResultUserPtr::operator=

(

AliEmcalTrackSelResultUserPtr &&

ref

)

Move assignment operator.

Connecting pointer instance to the storage connected to by ref. In case the pointer handles a storage itself disconnects from the storage

Parameters

ref	Object to be moved

Returns

Pointer instance after move

Definition at line 235 of file AliEmcalTrackSelResultPtr.cxx.
