java.lang.Object java.util.concurrent.atomic.AtomicIntegerArray
public class AtomicIntegerArray
An int array in which elements may be updated atomically.
See the java.util.concurrent.atomic
package
specification for description of the properties of atomic
variables.
Constructor Summary | |
---|---|
AtomicIntegerArray(int length)
Create a new AtomicIntegerArray of given length. |
|
AtomicIntegerArray(int[] array)
Create a new AtomicIntegerArray with the same length as, and all elements copied from, the given array. |
Method Summary | |
---|---|
int |
addAndGet(int i,
int delta)
Atomically add the given value to element at index i. |
boolean |
compareAndSet(int i,
int expect,
int update)
Atomically set the value to the given updated value if the current value == the expected value. |
int |
decrementAndGet(int i)
Atomically decrement by one the element at index i. |
int |
get(int i)

int |
getAndDecrement(int i)
Atomically decrement by one the element at index i. |
int |
getAndIncrement(int i)
Atomically increment by one the element at index i. |
int |
getAndSet(int i,
int newValue)
Set the element at position i to the given value and return the old value. |
int |
incrementAndGet(int i)
