    1.40 + * Interfaces and classes providing a framework for locking and waiting
    1.41 + * for conditions that is distinct from built-in synchronization and
    1.42 + * monitors.  The framework permits much greater flexibility in the use of
    1.43 + * locks and conditions, at the expense of more awkward syntax.
    1.44 + *
    1.45 + * <p>The {@link java.util.concurrent.locks.Lock} interface supports
    1.46 + * locking disciplines that differ in semantics (reentrant, fair, etc),
    1.47 + * and that can be used in non-block-structured contexts including
    1.48 + * hand-over-hand and lock reordering algorithms.  The main implementation
    1.49 + * is {@link java.util.concurrent.locks.ReentrantLock}.
    1.50 + *
    1.51 + * <p>The {@link java.util.concurrent.locks.ReadWriteLock} interface
    1.52 + * similarly defines locks that may be shared among readers but are
    1.53 + * exclusive to writers.  Only a single implementation, {@link
    1.54 + * java.util.concurrent.locks.ReentrantReadWriteLock}, is provided, since
    1.55 + * it covers most standard usage contexts.  But programmers may create
    1.56 + * their own implementations to cover nonstandard requirements.
    1.57 + *
    1.58 + * <p>The {@link java.util.concurrent.locks.Condition} interface
    1.59 + * describes condition variables that may be associated with Locks.
    1.60 + * These are similar in usage to the implicit monitors accessed using
    1.61 + * {@code Object.wait}, but offer extended capabilities.
    1.62 + * In particular, multiple {@code Condition} objects may be associated
    1.63 + * with a single {@code Lock}.  To avoid compatibility issues, the
    1.64 + * names of {@code Condition} methods are different from the
    1.65 + * corresponding {@code Object} versions.
    1.66 + *
    1.67 + * <p>The {@link java.util.concurrent.locks.AbstractQueuedSynchronizer}
    1.68 + * class serves as a useful superclass for defining locks and other
    1.69 + * synchronizers that rely on queuing blocked threads.  The {@link
    1.70 + * java.util.concurrent.locks.AbstractQueuedLongSynchronizer} class
    1.71 + * provides the same functionality but extends support to 64 bits of
    1.72 + * synchronization state.  Both extend class {@link
    1.73 + * java.util.concurrent.locks.AbstractOwnableSynchronizer}, a simple
    1.74 + * class that helps record the thread currently holding exclusive
    1.75 + * synchronization.  The {@link java.util.concurrent.locks.LockSupport}
    1.76 + * class provides lower-level blocking and unblocking support that is
    1.77 + * useful for those developers implementing their own customized lock
    1.78 + * classes.
    1.79 + *
