Detailed Description

Helper class handling the lifetime of the user object handled by AliEmcalTrackSelResultUserPtr.

Author: Markus Fasel marku.nosp@m.s.fa.nosp@m.sel@c.nosp@m.ern..nosp@m.ch, Oak Ridge National Laboratory

Since: Dec 11, 2017

Common storage class for multiple instances of AliEmcalTrackSelResultUserPointers. Together with the data the storage keeps track of the number of pointer instances connected to it via the reference count. Instances can connect and disconnect by the functions Connect and Release.

This class is foreseen to be used only from within AliEmcalTrackSelResultUserPtr. It is a suicide object which kills itself once it goes out-of-scope.

Member Function Documentation

void AliEmcalTrackSelResultUserStorage::Connect ( )

Connect new user pointer instance to the storage.

Used in the copy constructor and assignment operator of AliEmcalTrackSelResultUserPtr. This function is there in order to tell then storage that a new user pointer instance has connected to the storage. Increases the reference count. Not to be used outside of class AliEmcalTrackSelResultUserPtr

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

inline

Get the user data handled by the storage.

Returns: User data handled by the storage

Definition at line 100 of file AliEmcalTrackSelResultPtr.h.

Int_t PWG::EMCAL::AliEmcalTrackSelResultUserStorage::GetReferenceCount ( ) const

inline

Get the number of pointer instances connected to the storage.

Returns: Number of pointer instances connected to the storage

void AliEmcalTrackSelResultUserStorage::Release ( )

Release user pointer from the storage.

Used in the destructor of AliEmcalTrackSelUserPtr. This function is there in order to tell the storage that a user pointer instance has disconnected. Reduces the reference count. Not to be called ountside of class AliEmcalTrackSelResultUserPtr.
