        public static SherlockStub withReleasedLocks()
        Make the stub produce released locks by default
        Returns:
        the stub instance

      • withAcquiredLocks

        public static SherlockStub withAcquiredLocks()
        Make the stub produce acquired locks by default
        Returns:
        the stub instance

      • createReentrantLock

        public DistributedLock createReentrantLock​(java.lang.String lockId,
                                           java.time.Duration duration)
        Description copied from interface: Sherlock
        Create a distributed reentrant lock. Reentrant lock maybe acquired multiple times by the same application instance: 
        
 assert reentrantLock.acquire() == true
 assert reentrantLock.acquire() == true
        Specified by:
        createReentrantLock in interface Sherlock
        Parameters:
        lockId - the lock id
        duration - after that time lock expires and is released
        Returns:
        the reentrant lock

      • initialize

        public void initialize()
        Description copied from interface: Sherlock
        Initializes underlying infrastructure. If it's database then indexes and tables are created. If this method is not invoked directly then it is invoked implicitly when acquiring or releasing a lock for the first time.
        Specified by:
        initialize in interface Sherlock

      • createLock

        public DistributedLock createLock​(java.lang.String lockId,
                                  java.time.Duration duration)
        Description copied from interface: Sherlock
        Create a lock. Created lock may be acquired only once by the same application instance: 
        
 assert reentrantLock.acquire() == true
 assert reentrantLock.acquire() == false
        Specified by:
        createLock in interface Sherlock
        Parameters:
        lockId - the lock id
        duration - after that time lock expires and is released
        Returns:
        the lock

      • createOverridingLock

        public DistributedLock createOverridingLock​(java.lang.String lockId,
                                            java.time.Duration duration)
        Description copied from interface: Sherlock
        Create a distributed overriding lock. Returned lock overrides lock state without checking if it was released.
        Specified by:
        createOverridingLock in interface Sherlock
        Parameters:
        lockId - the lock id
        duration - after that time lock expires and is released
        Returns:
        the reentrant lock
