Member Function Documentation

◆ appendOndemand()

virtual int glo::OndemandLot::appendOndemand ( const Reference & rNewOndemand )

virtual

Appends a reference to a persistent object to the end of the container.

If the container is locked, the referenced object of the reference to be inserted is locked with the container lock mode.

If the container is monitored, the referenced object of the reference to be inserted is also monitored with the monitoring mode of the container.

Parameters

[in] rNewOndemand The reference to a persistent object to be inserted.

Returns: A return value < 0 indicates an error.

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

Reimplemented in glo::OndemandSet, and glo::OndemandList.

◆ appendPers()

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

virtual

Appends a persistent object to the end of the container.

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

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

Parameters

[in] pNewObj The persistent object to be inserted.

Returns: A return value < 0 indicates an error.

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

Reimplemented from glo::BaseLot.
