Simple smart pointer implementation inheriting from TObject which defines ownership in an object-by-object approach. The pointer will handle deletes only in case it is owner over the object.

Attention: This is a simplified version of a smart pointer, different pointers do not know from each other, which might lead into troubles once the object is copied. Can be done in a much more elegant way using c++11 shared_ptr.

Constructor & Destructor Documentation

AliEmcalManagedObject::AliEmcalManagedObject

(

)

Dummy constructor.

Definition at line 181 of file AliEmcalTrackSelection.cxx.

AliEmcalManagedObject::AliEmcalManagedObject	(	TObject *	object,
		bool	owner = true
	)

Default constructor, creates new managed object.

Parameters

[in]	object	Managed object
[in]	owner	Flag for ownership

Definition at line 189 of file AliEmcalTrackSelection.cxx.

AliEmcalManagedObject::AliEmcalManagedObject

(

const AliEmcalManagedObject &

ref

)

Copy constructor.

By default the new smart pointer will not own the object of the reference smart pointer.

Parameters

[in]

ref

Reference for the copy

Definition at line 196 of file AliEmcalTrackSelection.cxx.

virtual AliEmcalManagedObject::~AliEmcalManagedObject ( )

inlinevirtual

Destructor, will delete the managed object in case it is the owner

Definition at line 99 of file AliEmcalTrackSelection.h.

Member Function Documentation

void AliEmcalManagedObject::Cleanup ( )

protected

Cleanup managed object (remove if pointer is owner)

Definition at line 214 of file AliEmcalTrackSelection.cxx.

Referenced by operator=().

TObject* AliEmcalManagedObject::GetObject ( )

inline

Providing access to managed object.

Returns

Object managed by the smart pointer

Definition at line 136 of file AliEmcalTrackSelection.h.

Referenced by AliEmcalTrackSelection::GetTrackCuts(), and AliEmcalTrackSelectionESD::SaveQAObjects().

bool AliEmcalManagedObject::IsOwner ( ) const

inline

Checks whether the object is set.

Returns

True if pointer is owner of the object

Definition at line 111 of file AliEmcalTrackSelection.h.

AliEmcalManagedObject::operator bool ( ) const

inline

Check whether a managed object is set.

Returns

True if object is set, false otherwise

Definition at line 105 of file AliEmcalTrackSelection.h.

AliEmcalManagedObject & AliEmcalManagedObject::operator=

(

const AliEmcalManagedObject &

ref

)

Assignment operator By default the new smart pointer will not own the object of the reference smart pointer.

Parameters

[in]

ref

Reference for assignment

Returns

Pointer after assingment

Definition at line 203 of file AliEmcalTrackSelection.cxx.

void AliEmcalManagedObject::SetObject ( TObject *  managedObject, bool  owner = true  )

inline

Set new managed object with ownership.

In case the pointer managed already an object it will cleanup the object if necessary

Parameters

[in]	managedObject	New object managed by this smart pointer
[in]	owenr	Ownership status of the new object

Definition at line 126 of file AliEmcalTrackSelection.h.

void AliEmcalManagedObject::SetOwner ( bool  owner = true )

inline

Specifying ownership over object.

Parameters

[in]

owner

Ownership (if true then object takes over ownership)

private

Pointer to object handled by the smart pointer.

Bool_t AliEmcalManagedObject::fOwner

private

Switch defining ownership over object.
