Is the base class of a template list. The persistent objects are managed in a std::list.
Objects can also be inserted multiple times and in any order.

Constructor & Destructor Documentation

◆ PointerList() [1/3]

glo::PointerList::PointerList ( )

Standard constructor.

◆ PointerList() [2/3]

glo::PointerList::PointerList ( Base & rBase)

Constructor with parameter passing.

Parameters
[in]rBaseThe database in which the persistent objects are stored.

◆ ~PointerList()

virtual glo::PointerList::~PointerList ( )
virtual

Destructor, for all objects in the object list the list-specific lock and watch mode is cancelled, the reference counter is decremented by calling GloBasePersisten::forget() and then the object list is cleared.

◆ PointerList() [3/3]

glo::PointerList::PointerList ( const PointerList & )
private

The copy constructor is not available.

Member Function Documentation

◆ appendPers()

virtual int glo::PointerList::appendPers ( BasePersistent * pNewObj)
virtual

Appends a persistent object to the end of the list.

If the list is locked, the object to be inserted is locked with the lock mode of the list.

If the list is monitored, the object to be inserted is also monitored with the monitoring mode of the list.

Parameters
[in]pNewObjThe persistent object to be inserted. If no error, the linkcounter is incremented by pNewObj.
Returns
A return value < 0 indicates an error.
Attention
The internal iterator m_poObjListIterator points to the inserted element if the insertion is successful.

Reimplemented from glo::BaseLot.

◆ clear()

virtual void glo::PointerList::clear ( )
virtual

All objects are removed from the list. The list-specific lock and watching mode is removed for all objects in the list.

Implements glo::BaseLot.

◆ getAllClassIDs()

virtual void glo::PointerList::getAllClassIDs ( std::list< ObjID > & rAllClassIDs) const
virtual

See description in superclass.

◆ getPers()

virtual int glo::PointerList::getPers ( BasePersistent *& prRetVal,
EnSeekMode eMode )
virtual

Returns an object from the list in relation to eMode.

Parameters
[in,out]prRetValIf no error, the fetched object.
[in]eModeThe seek mode.

Parameter examples:

Returns
A return < 0 indicates an error. A return == ERR_RANGE indicates the end of the AllSet.
Attention
If prRetVal is valid, this object must be removed from memory by the calling instance.

Implements glo::PointerLot.

◆ getPersistent()

virtual int glo::PointerList::getPersistent ( BasePersistent *& prRetVal,
const ObjID & rObjID )
virtual

Returns an object with passed object ID from the container.

Parameters
[in,out]prRetValIf no error, the fetched object.
[in]rObjIDThe object ID.
Returns
A return value < 0 indicates an error.
Attention
If prRetVal is valid, this object must be removed from memory by the calling instance using BasePersistent::forget().

Implements glo::AbstractBaseLot.

◆ inLot() [1/3]

virtual bool glo::PointerList::inLot ( const BasePersistent & object) const
virtual

See description in superclass.

Reimplemented from glo::PointerLot.

◆ inLot() [2/3]

virtual bool glo::PointerList::inLot ( const ObjID & object) const
virtual

See description in superclass.

Implements glo::PointerLot.

◆ inLot() [3/3]

virtual bool glo::PointerList::inLot ( const std::shared_ptr< BasePersistent > object) const
virtual

See description in superclass.

Reimplemented from glo::PointerLot.

◆ insertPers()

virtual int glo::PointerList::insertPers ( BasePersistent * pNewObj)
virtual

Inserts a persistent object into the list behind the current position.

If the list is locked, the object to be inserted is locked with the lock mode of the list.

If the list is monitored, the object to be inserted is also monitored with the monitoring mode of the list.

Parameters
[in]pNewObjThe persistent object to be inserted. If no error, the linkcounter is incremented by pNewObj.
Returns
A return value < 0 indicates an error.
Attention
The internal iterator m_poObjListIterator points to the inserted element if the insertion is successful.

Reimplemented from glo::BaseLot.

◆ List()

std::list< BasePersistent * > & glo::PointerList::List ( )

Returns the reference to the internal object list.

Attention
This possibility of access should only be limited to accessing the objects with another iterator. Adding or removing objects can cause undefined behavior.
No object assignment may be made from the iterator without incrementing the reference counter ( see above BasePersistent::m_uiReferenceCount, BasePersistent::remember() and BasePersistent::forget().

◆ operator=()

PointerList & glo::PointerList::operator= ( const PointerList & )
inlineprivate

The assignment operator is not available.

◆ removePers()

virtual int glo::PointerList::removePers ( BasePersistent * pObject)
virtual

Removes persistent object from the list.

If the list is locked, the object to be removed is released with the lock mode of the list.

If the list is monitored, the monitoring of the object to be removed is ended with the monitoring mode of the list.

Parameters
[in]pObjectThe persistent object to be removed. The linkcounter of pObject is decremented, if in Set.
Returns
A return value < 0 indicates an error.
Attention
The internal iterator m_poObjListIterator points to the element following the removed one if the deletion was successful. If there is no subsequent element, the internal iterator m_poObjListIterator points to the container end.

Implements glo::PointerLot.

◆ setCurrentObject()

virtual int glo::PointerList::setCurrentObject ( const ObjID & rObjID)
virtual

Sets the internal iterator to the first position of the object with passed object ID.

Parameters
[in]rObjIDThe object ID.
Returns
A return value < 0 indicates an error.

Implements glo::AbstractBaseLot.

◆ setPosition()

virtual int glo::PointerList::setPosition ( std::size_t nPosition)
virtual

Sets the internal iterator to the passed position.

Parameters
[in]nPositionThe position to be set.
Returns
A return value < 0 indicates an error.

Implements glo::AbstractBaseLot.

◆ size()

virtual std::size_t glo::PointerList::size ( ) const
virtual

Returns the number of objects in the container.

Returns
The number or a return value < 0 indicates an error.

Implements glo::AbstractBaseLot.

Member Data Documentation
