public interface IMultiVersionOperations

The commit and rollback operations.

Author:

Method Summary

Modifier and Type	Method	Description
IVersion	commit(IEpoch epoch)	Commits the pending transient state at the specified epoch.
void	rollback()	Rolls back the changes that have been written in the transient state.

Method Detail

commit

IVersion commit(IEpoch epoch)

Commits the pending transient state at the specified epoch.

This automatically creates a new transient, writable state.

Thread-safety: unless specific otherwise by the implementing class, it is not thread-safe to call commit(IEpoch) and rollback() concurrently.

Parameters:

epoch - the epoch associated with this commit

Returns:

the version that prevails after this commit (possibly an untouched current version if the commit had absolutely no impact on the state)

rollback

void rollback()

Rolls back the changes that have been written in the transient state.

Thread-safety: unless specific otherwise by the implementing class, it is not thread-safe to call commit(IEpoch) and rollback() concurrently.
