Examples of LockingPolicy

• org.apache.derby.iapi.store.raw.LockingPolicy
  Any object that implements this interface can be used as a locking policy for accessing a container.

  The locking policy must use the defined lock qualifiers (ContainerLock.CIS, RowLock.RS, etc.) and the standard lock manager. (A locking policy that just performs no locking wouldn't need to use these :-)

  A locking policy must use the object that is an instance of Transaction (originally obtained via startTransaction() in RawStoreFactory) as the compatibilitySpace for the LockFactory calls.
  A locking policy must use the passed in transaction as the compatability space and the lock group. This chain (group) of locks has the following defined behaviour

  • Locks are released at transaction.commit()
  • Locks are released at transaction.abort()
