java.lang.Objectjava.util.concurrent.atomic.AtomicReference<V>
V - The type of object referred to by this referencepublic class AtomicReference<V>
An object reference that may be updated atomically. See the java.util.concurrent.atomic package specification for description
of the properties of atomic variables.
| Constructor Summary | |
|---|---|
AtomicReference()
Creates a new AtomicReference with null initial value. |
|
AtomicReference(V initialValue)
Creates a new AtomicReference with the given initial value. |
|
| Method Summary | |
|---|---|
boolean |
compareAndSet(V expect,
V update)
Atomically sets the value to the given updated value if the current value == the expected value. |
V |
get()
Gets the current value. |
V |
getAndSet(V newValue)
Atomically sets to the given value and returns the old value. |
void |
lazySet(V newValue)
Eventually sets to the given value. |
void |
set(V newValue)
Sets to the given value. |
String |
toString()
Returns the String representation of the current value. |
boolean |
weakCompareAndSet(V expect,
V 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.

public final V getAndSet(V newValue)
newValue - the new value
public String toString()
toString in class Object
