Classes in com.bigdata.concurrent used by com.bigdata.concurrent

Class and Description
AbstractStressTestNonBlockingLockManager Suite of stress tests of the concurrency control mechanisms (without the database implementation) - See NonBlockingLockManager.
AccessSemaphore.Access
DeadlockException An instance of this exception is thrown when the lock requests of two or more transactions form a deadlock.
FutureTaskMon This is a flyweight utility class to be used as a direct replacement for FutureTask in code where we may need to be able to discover the root cancel request causing an interrupt.
LockCallable Bundles the resources identifying the required locks with the task to be executed once it holds those locks.
LockManager Deprecated. This implementation manages locks in terms of threads. A thread is required in order for a task to contend for its locks. This places a strain on the thread scheduler.
NonBlockingLockManager.LockFutureTask FutureTask which executes once it holds its locks.
NonBlockingLockManager.RunState Run states for the NonBlockingLockManager.
NonBlockingLockManagerWithNewDesign This class coordinates a schedule among concurrent operations requiring exclusive access to shared resources.
NonBlockingLockManagerWithNewDesign.LockFutureTask FutureTask which executes once it holds its locks.
NonBlockingLockManagerWithNewDesign.StatisticsTask Class for tracking the average queue size of each ResourceQueue and various other moving averages for the service as a whole.
TxDag Directed Acyclic Graph (DAG) for detecting and preventing deadlocks in a concurrent programming system.
TxDag.Edge A representation of an edge in the DAG used for export of information to the caller.
