But typically the abstract class AbstractRecoveryExecutor can be used as super class.

 

After implementing a new recovery executor, it must be declared as an OSGi declarative service that provides an implementation of IRecoveryExecutor.

 

If you want to use the checkpointing component to get a notification when a checkpoint is reached, you have to register like in the following example:

Code Block
languagejava
titleUsage of Checkpointing
RollbackRecoveryExecutor instance = new RollbackRecoveryExecutor();
List<IRecoveryComponent> components = new ArrayList<>();
components.add(new CheckpointingRecoveryComponent());
components.add(new ProcessingImageRecoveryComponent());
components.add(new BaDaStRecoveryComponent());
components.add(new DuplicatesDetectorRecoveryComponent());
instance.init(config, components);
((CheckpointingRecoveryComponent) instance.components.get(0))
		.addCheckpointManagerListener((ProcessingImageRecoveryComponent) instance.components.get(1));
return instance;
