Class TimeSlotLockService

java.lang.Object

overit.geocallapp.wfm.scheduling.bl.lock.service.TimeSlotLockService

All Implemented Interfaces:

LockService

public class TimeSlotLockService
extends Object
implements LockService

TimeSlotLockService is an implementation of the LockService interface that manages locks using a database-based approach. This service ensures that resources, activities, and operation centers are locked within specified time slots to prevent concurrent access during scheduling operations. The locks are stored and managed in a database, providing a persistent and reliable mechanism for coordinating access to shared resources. The lock is associated with a unique identifier (UUID) for each transaction, allowing for efficient management and release of locks at the end of the transaction.

Since:

18.0

Method Details

acquireLock

public boolean acquireLock(String uuid,
 String key,
 int timeout)
                    throws DAValidateException,
DAException

This method acquires a new lock

Specified by:

acquireLock in interface LockService

Parameters:

uuid - the uuid

key - the lock key

timeout - the timeout after which the lock expires

Throws:

DAException

DAValidateException

releaseLock

public void releaseLock(String uuid)
                 throws DAException,
DAValidateException

This method releases a lock by uuid

Specified by:

releaseLock in interface LockService

Parameters:

uuid - the uuid

Throws:

DAException

DAValidateException

releaseAllLocks

public void releaseAllLocks()
                     throws DAException,
DAValidateException

Specified by:

releaseAllLocks in interface LockService

Throws:

DAException

DAValidateException

extendLock

public void extendLock(String uuid,
 int timeout)
                throws DAValidateException,
DAException

This method extends a lock by uuid

Specified by:

extendLock in interface LockService

Parameters:

uuid - the uuid

timeout - the timeout

Throws:

DAException

DAValidateException

isLocked

public boolean isLocked(String baseLockKey,
 boolean checkTotalCOScope)
                 throws DAValidateException,
DAException

This method checks if the entity is locked. If checkTotalScope is true, it verifies whether the entire operation center is locked. Otherwise, it checks for a partial or total lock on that operation center.

Specified by:

isLocked in interface LockService

Parameters:

baseLockKey - the base lock key composed by operation center and eventually scheduling model

checkTotalCOScope - if true verifies whether the entire operation center is locked

Throws:

DAException

DAValidateException
