Member Function Documentation

checkAndApplyRestore()

virtual bool Arcane::IBackwardMng::checkAndApplyRestore ( )

pure virtual

Checks and applies restoration if necessary.

Return values

true	if a restoration is performed.

checkAndApplySave()

virtual bool Arcane::IBackwardMng::checkAndApplySave ( bool is_forced )

pure virtual

Checks and applies variable saving if necessary. If is_forced is true, forces the save.

Return values

true	if a save is performed.

clear()

virtual void Arcane::IBackwardMng::clear ( )

pure virtual

Deletes resources associated with the backward rollback.

This method is called to deallocate resources such as variable saves. This method is called among other things before a load balancing because it will not be possible to perform a backward rollback before this balancing.

goBackward()

virtual void Arcane::IBackwardMng::goBackward ( )

pure virtual

Signals that a backward rollback is desired.

The backward rollback will occur when checkAndApplyRestore() is called.

Generally, this method should not be called directly but rather ITimeLoopMng::goBackward().

From the call to this method until the effective action of the backward rollback when calling checkAndApplyRestore(), isBackwardEnabled() returns true.

isBackwardEnabled()

virtual bool Arcane::IBackwardMng::isBackwardEnabled ( ) const

pure virtual

Indicates if a backward rollback is scheduled.

See also

goBackward().

isLocked()

virtual bool Arcane::IBackwardMng::isLocked ( ) const

pure virtual

Indicates if the backward rollback saves are locked.

isLocked() is true if it is not possible to perform a save. This is the case, for example, when a backward rollback has been performed at iteration M to iteration N and we have not yet returned to iteration M.
