java.lang.Objectjava.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)
Get the current value at position i. |
int |
getAndAdd(int i,
int delta)
Atomically add the given value to element at index 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)
Atomically increment by one the element at index i. |
int |
length()
Returns the length of the array. |
void |
set(int i,
int newValue)
Set the element at position i to the given value. |
String |
toString()
Returns the String representation of the current values of array. |
boolean |
weakCompareAndSet(int i,
int expect,
int update)
Atomically set the value to the given updated value if the current value == the expected value. |
