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] rBase The 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] pNewObj The 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]	prRetVal	If no error, the fetched object.
[in]	eMode	The seek mode.

Parameter examples:

glo::START = returns first element
glo::END = returns last element
glo::CURRENT = returns current element
glo::NEXT = returns next element
glo::PREVIOUS = returns previous element

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]	prRetVal	If no error, the fetched object.
[in]	rObjID	The 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] pNewObj The 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] pObject The 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] rObjID The 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] nPosition The 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.
