AtomicLongArray JDK 1.6)

public long addAndGet (int i, long delta)

Atomically adds the given value to the element at index i.

Atomically adds the given value to the element at index i.
Returns: the updated value
Parameters:
- i - the index
- delta - the value to add

publicfinal boolean compareAndSet (int i, long expect, long update)

Atomically sets the value to the given updated value if the current value == the expected value.

Atomically sets the value to the given updated value
if the current value == the expected value.
Returns: true if successful. False return indicates that the actual value was not equal to the expected value.
Parameters:
- i - the index
- expect - the expected value
- update - the new value

publicfinal long decrementAndGet (int i)

Atomically decrements by one the element at index i.

Atomically decrements by one the element at index i.
Returns: the updated value
Parameters:
- i - the index

publicfinal long get (int i)

Gets the current value at position i.

Gets the current value at position i.
Returns: the current value
Parameters:
- i - the index

publicfinal long getAndAdd (int i, long delta)

Atomically adds the given value to the element at index i.

Atomically adds the given value to the element at index i.
Returns: the previous value
Parameters:
- i - the index
- delta - the value to add

publicfinal long getAndDecrement (int i)

Atomically decrements by one the element at index i.

Atomically decrements by one the element at index i.
Returns: the previous value
Parameters:
- i - the index

publicfinal long getAndIncrement (int i)

Atomically increments by one the element at index i.

Atomically increments by one the element at index i.
Returns: the previous value
Parameters:
- i - the index

publicfinal long getAndSet (int i, long newValue)

Atomically sets the element at position i to the given value and returns the old value.

Atomically sets the element at position i to the given value
and returns the old value.
Returns: the previous value
Parameters:
- i - the index
- newValue - the new value

publicfinal long incrementAndGet (int i)

Atomically increments by one the element at index i.

Atomically increments by one the element at index i.
Returns: the updated value
Parameters:
- i - the index

publicfinal void lazySet (int i, long newValue)

Eventually sets the element at position i to the given value.

Eventually sets the element at position i to the given value.
Parameters:
- i - the index
- newValue - the new value
Since: 1.6

publicfinal int length ()

Returns the length of the array.

publicfinal void set (int i, long newValue)

Sets the element at position i to the given value.

Sets the element at position i to the given value.
Parameters:
- i - the index
- newValue - the new value

public String toString ()

Returns the String representation of the current values of array.

publicfinal boolean weakCompareAndSet (int i, 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.
Returns: true if successful.
Parameters:
- i - the index
- expect - the expected value
- update - the new value
