public interface Compensation

extends Loggable

A Compensation operation can compensate for the action of a log operation. A Compensation operation itself is not undo-able, i.e., it is loggable but not undoable. A Compensation operation is generated by the logging system when it calls undoable.generateUndo(). GenerateUndo should be the only way a compensation operation can be made.
