Detailed Description

template<class T>
class glo::TPointerList< T >

A type-safe list of pointers to persistent objects in the database (intended as an attribute for persistent objects).

Objects can also be inserted multiple times and in any order.

When a persistent object with an attribute of type TPointerList is loaded from the database into memory, the objects contained in the TPointerList are automatically loaded into memory.

This class ensures that the method Persistent::forget() of the contained objects is called when the object is destroyed.

When an object is delivered, the method Persistent::remember() is called.

Member Function Documentation

◆ append() [1/2]

template<class T >

int glo::TPointerList< T >::append ( std::shared_ptr< T > spNewObj )

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] spNewObj The persistent object to be inserted in a std::shared_ptr.

Returns: A return value < 0 indicates an error.

Attention: The internal iterator m_poObjListIterator points to the inserted element if the insertion is successful.

◆ append() [2/2]

template<class T >

int glo::TPointerList< T >::append ( T * 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.

◆ get() [1/2]

template<class T >

int glo::TPointerList< T >::get	(	std::shared_ptr< T > &	rRetVal,
		EnSeekMode	eMode )

virtual

Returns an object from the list in relation to eMode.

Parameters

[in,out]	rRetVal	If no error, the fetched object in a std::shared_ptr.
[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.

◆ get() [2/2]

template<class T >

int glo::TPointerList< T >::get	(	T *&	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.

◆ getTypeAsString()

template<class T >

int glo::TPointerList< T >::getTypeAsString ( std::string & rsTypeName )

overridevirtual

Returns the type of the template list, i.e. the class name as string when connected to the database.

Parameters

[in,out] rsTypeName The type name.

Returns: If return value < 0, an error has occurred.

Reimplemented from glo::BaseLot.

◆ insert() [1/2]

template<class T >

int glo::TPointerList< T >::insert ( std::shared_ptr< T > spNewObj )

virtual

Inserts the passed 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] spNewObj The persistent object to be inserted in a std::shared_ptr.

Returns: A return value < 0 indicates an error.

Attention: The internal iterator m_poObjListIterator points to the inserted element if the insertion is successful.

◆ insert() [2/2]

template<class T >

int glo::TPointerList< T >::insert ( T * pNewObj )

virtual

Inserts the passed 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.

◆ insertBefore() [1/2]

template<class T >

int glo::TPointerList< T >::insertBefore	(	std::shared_ptr< T >	spNewObj,
		const std::shared_ptr< T >	spObject )

virtual

Inserts a persistent object before another object in 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]	spNewObj	The persistent object to be inserted in a std::shared_ptr.
[in]	spObject	The subsequent persistent object.

Returns: A return value < 0 indicates an error.

Attention: The internal iterator m_poObjListIterator points to the inserted element if the insertion is successful.

◆ insertBefore() [2/2]

template<class T >

int glo::TPointerList< T >::insertBefore	(	T *	pNewObj,
		const T *	pObject )

virtual

Inserts a persistent object before another object in 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.
[in]	pObject	The subsequent persistent object.

Returns: A return value < 0 indicates an error.

Attention: The internal iterator m_poObjListIterator points to the inserted element if the insertion is successful.

◆ operator=()

template<class T >

TPointerList< T > & glo::TPointerList< T >::operator= ( const TPointerList< T > & )

private

The assignment operator is not available.

◆ remove() [1/2]

template<class T >

int glo::TPointerList< T >::remove ( std::shared_ptr< T > spObject )

virtual

Removes the passed 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] spObject The persistent object to be removed in a std::shared_ptr.

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.

◆ remove() [2/2]

template<class T >

int glo::TPointerList< T >::remove ( T * pObject )

virtual

Removes the passed 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 pObj is decremented, if in list.

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.
