Detailed Description

Abstract base class for Persistent and the generic GenericPersistent.

Objects of this type have a reference counter and must not be removed from memory using the destructor.
Objects with reference counters may only be instantiated once. When passing to another instance, the reference counter must be incremented using BasePersistent::remember().
If the owning instance no longer needs the object, the reference counter is decremented via BasePersistent::forget().
When the reference counter runs to 0, the destructor is called automatically.

Constructor & Destructor Documentation

◆ BasePersistent() [1/2]

glo::BasePersistent::BasePersistent ( )

Standard constructor.

◆ ~BasePersistent()

virtual glo::BasePersistent::~BasePersistent ( )
protectedvirtual

Destructor, if necessary memory is cleared.
The destructor is not available. The object may only be removed from memory using forget().

◆ BasePersistent() [2/2]

glo::BasePersistent::BasePersistent ( const BasePersistent & )

Copy constructor. No attributes of this class are copied!

Member Function Documentation

◆ activate()

virtual void glo::BasePersistent::activate ( )
virtual

Is always called after the fetch from the database.
In derived classes, you can, for example, set pointers to NULL_PTR, set 'non-persistent' variables and/or perform other initializations.

◆ assign()

virtual int glo::BasePersistent::assign ( Base & rBase)
virtual

By means of this method, an object of this class is made known to the database and (if successful) receives a unique ObjID (if not already registered).
Only after this method has been called can an object be saved. A persistent object only needs to be logged on to the database once, before it is saved for the first time. Afterwards it keeps its unique ObjID.

Parameters
[in]rBaseThe database in which the object is to be stored.
Returns
A return value < 0 indicates an error.
Note
The transferred database must be open.

Reimplemented in glo::Persistent.

◆ deleteInBase()

virtual int glo::BasePersistent::deleteInBase ( EnDeepMode eDeepMode = DM_SHALLOW)
virtual

The object respectively its persistent attributes are deleted in the database.

Parameters
[in]eDeepModeThe deleting depth mode.
Returns
A return < 0 indicates an error.

Reimplemented in glo::Persistent.

◆ forget()

virtual unsigned int glo::BasePersistent::forget ( )
virtual

An object of this class should always be delivered with a previous call to BasePersistent::remember(). The delivered instance must then 'forget' the object using this method.

Returns
The return value is the number of references to the object of this class.
Exceptions
eut::ErrorNExceptionAn exception is thrown if the reference counter wants to go into minus.
Note
It is recommended, if possible, to consider using std::shared_ptr in conjunction with Forgeter.

Reimplemented in glo::GenericPersistent.

const std::vector< unsigned long > * pClassIdVector = 0 ) const

Returns all names of the persistent attributes from its record.

Parameters

Note
It is recommended, if possible, to consider using std::shared_ptr in conjunction with Forgeter.

Reimplemented in glo::GenericPersistent.

◆ removeBase()

Note
To cancel the monitoring, the corresponding method unsetWatch(const WatchSpecification&) const must be used with the same parameter values.
In principle, it is possible to cancel individual watching modes. Care should then be taken that all individual watching modes are also applied so that no watching remains in the memory until the program is terminated.
Finally, the method Persistent::setWatch(TdWatchNotifyMode,EnDeepMode,CallBack*) is called.
See also
Watch and notify.

◆ setWatch() [2/2]

virtual int glo::BasePersistent::setWatch ( TdWatchNotifyMode ulWatchMode,
EnDeepMode eDeepMode,
CallBack * pCallBack = 0 )
virtual

The object is monitored in the database.

Parameters
[in]ulWatchModeThe watch mode.
Allowed watch modes:
[in]eDeepModeThe watching depth mode.
[in]pCallBackThe CallBack object that is notified via its method CallBack::notify(NotifyNote&). If no CallBack is passed, notify(NotifyNote&) is taken from this; in this case the method notify(NotifyNote&) should be overwritten in the respective derived class.
Returns
A return value < 0 indicates an error.
Note
To remove the monitoring, the corresponding method unsetWatch(TdWatchNotifyMode, EnDeepMode, CallBack*) const with same parameter values can be used.
In principle, it is possible to cancel individual watching modes. Care should then be taken that all individual watching modes are also applied so that no watching remains in the memory until the program is terminated.
Attention
Basically pCallBack must not be destroyed before the monitoring has been cancelled!
See also
Watch and notify.

Reimplemented in glo::Persistent.

Reimplemented in glo::GenericPersistent, and glo::Persistent.

◆ unlock() [1/2]

virtual int glo::BasePersistent::unlock ( const LockSpecification & rLockSpecification)

Parameters
[in]eLockModeThe original lock mode.
[in]eDeepModeThe original lock depth mode.
Returns
A return < 0 indicates an error.
Note
Removes the lock initiated by the corresponding method lock(EnLockMode, EnDeepMode) const if the parameters have the same values.

Locking a persistent object.

Reimplemented in glo::Persistent.

◆ unsetWatch() [1/2]

virtual int glo::BasePersistent::unsetWatch ( const WatchSpecification & rWatchSpec)
virtual

The monitoring of the object in the database is terminated. A monitoring termination must be called with the same parameters as the previous monitoring.

Parameters
[in]rWatchSpecThe original monitoring specification.
Returns
A return < 0 indicates an error.
Note
Clears the monitoring initiated by the corresponding method setWatch(const WatchSpecification&) const if the parameters have the same values.
In principle, it is possible to cancel individual watching modes. Care should then be taken that all individual watching modes are also applied so that no watching remains in the memory until the program is terminated.
Finally, the method Persistent::unsetWatch(TdWatchNotifyMode,EnDeepMode,CallBack*) is called.
See also
Watch and notify.

◆ unsetWatch() [2/2]

virtual int glo::BasePersistent::unsetWatch ( TdWatchNotifyMode ulWatchMode,
EnDeepMode eDeepMode,
CallBack * pCallBack = 0 )
virtual

The monitoring of the object in the database is terminated. A monitoring termination must be called with the same parameters as the previous monitoring.

Parameters
[in]ulWatchModeThe original watch mode.
Allowed watch modes:
[in]eDeepModeThe original monitoring depth mode.
[in]pCallBackThe CallBack object that was notified via its method CallBack::notify(NotifyNote&). If no CallBack is passed, notify(NotifyNote&) is taken from this; in this case the method notify(NotifyNote&) should be overwritten in the respective derived class.
Returns
A return value < 0 indicates an error.
Note
Clears the monitoring initiated by the corresponding method setWatch(TdWatchNotifyMode, EnDeepMode, CallBack*) const if the parameters have the same values.
In principle, it is possible to cancel individual watching modes. Care should then be taken that all individual watching modes are also applied so that no watching remains in the memory until the program is terminated.

Member Data Documentation

◆ m_bSpyaction

bool glo::BasePersistent::m_bSpyaction
protected

If false, the object in the destructor of the subclasses (see also there) is not removed from Objektspy (if necessary it should not exist there).
For example, is set to false by PrivateBase when reinstantiating an embedded object.
Default setting = true.

◆ m_LocalCriticalSection

eut::CriticalSection glo::BasePersistent::m_LocalCriticalSection
protected

To allow multiple threads to access BasePersistent::remember() and BasePersistent::forget(), access is synchronized with this CriticalSection.

◆ m_pRecord

Record* glo::BasePersistent::m_pRecord
protected

The data set of the object is merged from several data sets in these if necessary.

◆ m_uiReferenceCount

unsigned int glo::BasePersistent::m_uiReferenceCount
protected

The reference counter. See also the class description of BasePersistent.
