com.thinkaurelius.titan.diskstorage.locking.LockerState<S>

Type Parameters:

S - The LockStatus type.

public class LockerState<S>

A store for LockStatus objects. Thread-safe so long as the method calls with any given StoreTransaction are serial. Put another way, thread-safety is only broken by concurrently calling this class's methods with the same StoreTransaction instance in the arguments to each concurrent call.
