OfflineOData UndoPendingChanges

While you can make changes to existing entities and new entities locally, you can also undo the pending changes without uploading them by calling the UndoPendingChanges Action for an entity object . An existing entity will be restored to the original status as if no any changes had been made. A new entity will be removed as if the entity had never been created, and a deleted entity will be restored to the offline store.

The properties defined in Action are also applicable to this action.
