Locking

The locking-related methods provided by the JoobContext class are shown in the following table.

Method	Description
Lock	Locks a JADE object and throws an exception if the attempt fails
Unlock	Releases a lock on a JADE object
TryLock	Locks a JADE object and returns False if the attempt fails
GetLockStatus	Gets the type and duration of the lock on a JADE object by the current process

In the following example, an attempt is made to lock an agent object using the Lock method. If the object is already locked with an incompatible lock, a normal lock exception is thrown. The JADE concepts of passback, continue, resume, or abort (for the action that is taken after the exception handling code has been executed) are not supported.

JoobContext context = JoobContext.CurrentContext;
Agent agent = context.FirstInstance<Agent>();
try
{
    context.Lock(agent,                     // object to be locked
                 LockType.Exclusive,        // type of lock
                 LockDuration.Session,      // session/transaction duration
                 TimeSpan.FromSeconds(5));  // time before exception thrown
}
catch (JoobObjectLockedException)
{
                                            // lock object handling code
}
