PaddedAtomicLong
public PaddedAtomicLong()Creates a new PaddedAtomicLong with initial value0
. -
PaddedAtomicLong
public PaddedAtomicLong(long initialValue) Creates a new PaddedAtomicLong with the given initial value.- Parameters:
initialValue
- the initial value
-
-
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 valueupdate
- 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 valueupdate
- 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
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
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
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 valuef
- a side-effect-free function of two arguments- Returns:
- the previous value
- See Also:
-
accumulateAndGet
-
toString
Returns the String representation of the current value. -
