Detailed Description

template<class T>
class glo::TOndemandList< T >

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

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

In contrast to a TPointerList (where the referenced objects are automatically 'loaded'), the TOndemandList is a list of references; the referenced objects are not loaded from the database with the referencing object, but can be 'reloaded' if required.

It is always useful if an object is to reference several 'large' objects that do not have to be available.

Parameters
[in]NewObjThe persistent object to be inserted.
Returns
A return value < 0 indicates an error.
Attention

int glo::TOndemandList< T >::append ( T * NewObj)
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]NewObjThe persistent object to be inserted.
Returns
A return value < 0 indicates an error.

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

◆ get() [2/5]

Returns an object from the list in relation to eMode.

Parameters

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().

◆ get() [4/5]

template<class T >
int glo::TOndemandList< T >::get ( T *& 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.
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.

◆ get() [5/5]

template<class T >

EnSeekMode eMode )
virtual

Returns an object from the list in relation to eMode.

Parameters
[in,out]rRetValIf no error, the fetched object in a std::shared_ptr.
[in]eModeThe seek mode.
Returns
A return < 0 indicates an error. A return == ERR_RANGE indicates the end of the AllSet.

◆ getTypeAsString()

template<class T >
int glo::TOndemandList< 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
