Interface LockStore

All Known Implementing Classes:

AbstractLockStore, LockStoreImpl

public interface LockStore

Defines the in-memory lock storage interface.

Individual operations MUST be thread-safe, however clients are expected to synchronise compound operations using LockStore.acquireConcurrencyLock(NodeRef) and LockStore.releaseConcurrencyLock(NodeRef), for example:

    acquireConcurrencyLock(nodeRef);
    try
    {
       if (lockStore.contains(nodeRef))
       {
          if (someOtherCondition())
          {
             lockStore.setUnlocked(nodeRef);
          }
       }
    }
    finally
    {
       releaseConcurrencyLock(nodeRef);
    }
