package org.cojen.tupl.util
Low-level utility classes for managing concurrency, caching, and task scheduling.
  • Class
    Description
    Canonicalizer
    Implements a specialized cache for supporting object canonicalization.
    Clutch
    A clutch is a specialized latch which can support highly concurrent shared requests, under the assumption that exclusive requests are infrequent.
    Clutch.Pack
    Sharable object for supporting contended clutches.
    Latch
    Non-reentrant read-write latch, designed for throughput over fairness.
    Latch.Condition
    Manages a queue of waiting threads, associated with a Latch instance.
    LocalPool<B>
    Utility for sharing a small set of poolable objects (like buffers) which have thread affinity.
    LocalPool.Entry<B>
    Entry within a LocalPool.
    Parker
    Alternative to directly using LockSupport for parking and unparking threads, which is much faster when threads are parked briefly.
    Runner
    Implements an unbounded pool of daemon threads which automatically exit when idle.
    WeakPool<B>
    Utility for sharing a small set of poolable objects (like buffers) which are weakly referenced.
    WeakPool.Entry<B>
    An entry which weakly references a pooled object.
    WideLatch
    Non-reentrant latch implementation which supports highly concurrent shared requests, but exclusive requests are more expensive.
    Worker
    Simple task worker which has at most one background thread, and is expected to have only one thread enqueuing tasks.
    Worker.Task
    One-shot worker task instance.
    WorkerGroup
    A group of workers for running tasks.
