  • Method Details

    • get

      public long get()
      Gets the current value.
      Returns:
      the current value
      See Also:

    • set

      public void set(long newValue)
      Sets to the given value.
      Parameters:
      newValue - the new value
      See Also:

    • lazySet

      public void lazySet(long newValue)
      Eventually sets to the given value.
      Parameters:
      newValue - the new value
      See Also:

    • getAndSet

      public long getAndSet(long newValue)
      Atomically sets to the given value and returns the old value.
      Parameters:
      newValue - the new value
      Returns:
      the previous value
      See Also:

    • compareAndSet

      public boolean compareAndSet(long expect, long update)
      Atomically sets the value to the given updated value if the current value == the expected value.
      Parameters:
      expect - the expected value
      update - the new value
      Returns:
      true if successful. False return indicates that the actual value was not equal to the expected value.
      See Also:

    • weakCompareAndSet

      public boolean weakCompareAndSet(long expect, long update)
      Atomically sets the value to the given updated value if the current value == the expected value.

      May fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to compareAndSet.

      Parameters:
      expect - the expected value
      update - the new value
      Returns:
      true if successful
      See Also:

    • getAndIncrement

      public long getAndIncrement()
      Atomically increments the current value by 1.
      Returns:
      the previous value
      See Also:

    • getAndDecrement

      public long getAndDecrement()
      Atomically decrements the current value by 1.
      Returns:
      the previous value
      See Also:

    • getAndAdd

      public long getAndAdd(long delta)
      Atomically adds to the current value the given value.
      Parameters:
      delta - the value to add
      Returns:
      the previous value
      See Also:

    • incrementAndGet

      public long incrementAndGet()
      Atomically increments the current value by one.
      Returns:
      the updated value
      See Also:

    • decrementAndGet

      public long decrementAndGet()
      Atomically decrements the current value by one.
      Returns:
      the updated value
      See Also:

    • addAndGet

      public long addAndGet(long delta)
      Atomically adds to current value te given value.
      Parameters:
      delta - the value to add
      Returns:
      the updated value
      See Also:

    • getAndUpdate

      public long getAndUpdate(LongUnaryOperator updateFunction)
      Atomically updates the current value with the results of applying the given function, returning the previous value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads.
      Parameters:
      updateFunction - a side-effect-free function
      Returns:
      the previous value
      See Also:

    • updateAndGet

      public long updateAndGet(LongUnaryOperator updateFunction)
      Atomically updates the current value with the results of applying the given function, returning the updated value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads.
      Parameters:
      updateFunction - a side-effect-free function
      Returns:
      the updated value
      See Also:

    • getAndAccumulate

      public long getAndAccumulate(long v, LongBinaryOperator f)
      Atomically updates the current value with the results of applying the given function to the current and given values, returning the previous value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. The function is applied with the current value as its first argument, and the given update as the second argument.
      Parameters:
      v - the update value
      f - a side-effect-free function of two arguments
      Returns:
      the previous value
      See Also:
