public @interface DistributedStaticMutexLocks

Annotation to declare a container for static locks to which same default values should get applied. Also allows to declare multiple DistributedMutexLock annotations at a method.

Required Element Summary

DistributedStaticMutexLock[]

locks

Optional Element Summary

int	lockOrderNumber If multiple locks should be done, than the lock order number (=lock priority) defines in which order the locks should be done.
long	maxLockWaitTime The maximum amount of milliseconds to wait for get the mutex locked.

Element Detail

locks

public abstract DistributedStaticMutexLock[] locks

Since:

0.0.1 (sasl-aop-distributed-lock)

maxLockWaitTime

public abstract long maxLockWaitTime

The maximum amount of milliseconds to wait for get the mutex locked. Values lesser or equal to zero mean eternal wait time. The default value is zero. The setting will only override the default setting (max lock wait time was not set) of values in the locks() array.

Since:

0.0.1 (sasl-aop-distributed-lock)

Default:

0L

lockOrderNumber

public abstract int lockOrderNumber

If multiple locks should be done, than the lock order number (=lock priority) defines in which order the locks should be done. Lower values mean lock first. If there are multiple annotations with the same order number, than the lock order for these is arbitrary. A lock order should be always declared, as it reduces deadlock problems. The setting will only override the default setting (lock order number was not set) of values in the locks() array.

Since:

0.0.1 (sasl-aop-distributed-lock)
