Interface DelegatedTransactionRecoveryFence

public interface DelegatedTransactionRecoveryFence

Interface to implement by delegated transaction recovery lock

Method Summary

Modifier and Type	Method and Description
String	getInstanceRecoveredFor(String path, long timestamp) Returns instance for which delegated recovery was done before the timestamp specified on the specified path or null if such instance does not exist
boolean	isFenceRaised(String path, String instanceName, long timestamp) Returns true if the specified instance on the specified path is being recovered after the specified timestamp
void	lowerFence(String path, String instanceName) Lower the fence for the specified instance on the specified path
void	raiseFence(String path, String instanceName) Raise the fence for the specified instance on the specified path so that no other instance can start delegated recovery at the same time.
void	transferRecoveryTo(String path, String instanceName) If an instance was doing delegated recovery on the specified path, assign specified instance instead.
