Class LockResult

java.lang.Object

com.sleepycat.je.txn.LockResult

public class LockResult
extends Object

LockResult is the return type of Locker.lock(). It encapsulates a LockGrantType (the return type of LockManager.lock()) and a WriteLockInfo. The WriteLockInfo field is non-null if (a) the locker is transactional, and (b) the request was for a WRITE or WRITE_RANGE lock, and (c) the request was not a non-blocking request that got denied. If so, the WriteLockInfo is either a newly created one or a pre-existing one if the same locker had write-locked the same LSN before.
