Interface AsyncAtomicReference<E>

Type Parameters:

E - the type of object referred to by this reference

All Superinterfaces:

DistributedObject, IAtomicReference<E>

All Known Implementing Classes:

AtomicReferenceProxy

Deprecated.

@Beta
 @Deprecated
public interface AsyncAtomicReference<E>
extends IAtomicReference<E>

A IAtomicReference that exposes its operations using a ICompletableFuture so it can be used in the reactive programming model approach.

Instead of this interface, use the equivalent async methods in the public IAtomicReference interface. This interface has been deprecated and will be removed in a future version.

Since:

3.2

Method Summary

Modifier and Type	Method and Description
ICompletableFuture<Void>	asyncAlter(IFunction<E,E> function) Deprecated. Alters the currently stored reference by applying a function on it.
ICompletableFuture<E>	asyncAlterAndGet(IFunction<E,E> function) Deprecated. Alters the currently stored reference by applying a function on it and gets the result.
<R> ICompletableFuture<R>	asyncApply(IFunction<E,R> function) Deprecated. Applies a function on the value, the actual stored value will not change.
ICompletableFuture<Void>	asyncClear() Deprecated. Clears the current stored reference.
ICompletableFuture<Boolean>	asyncCompareAndSet(E expect, E update) Deprecated. Atomically sets the value to the given updated value only if the current value == the expected value.
ICompletableFuture<Boolean>	asyncContains(E value) Deprecated. Checks if the reference contains the value.
ICompletableFuture<E>	asyncGet() Deprecated. Gets the current value.
ICompletableFuture<E>	asyncGetAndAlter(IFunction<E,E> function) Deprecated. Alters the currently stored reference by applying a function on it on and gets the old value.
ICompletableFuture<E>	asyncGetAndSet(E newValue) Deprecated. Gets the value and sets the new value.
ICompletableFuture<Boolean>	asyncIsNull() Deprecated. Checks if the stored reference is null.
ICompletableFuture<Void>	asyncSet(E newValue) Deprecated. Atomically sets the given value.
ICompletableFuture<E>	asyncSetAndGet(E update) Deprecated. will be removed from Hazelcast 3.4 since it doesn't really serve a purpose.

Method Detail

asyncCompareAndSet

ICompletableFuture<Boolean> asyncCompareAndSet(E expect,
                                               E update)

Deprecated.

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

Parameters:

expect - the expected value

update - the new value

Returns:

true if successful; or false if the actual value was not equal to the expected value.

asyncGet

ICompletableFuture<E> asyncGet()

Deprecated.

Gets the current value.

Returns:

the current value

asyncSet

ICompletableFuture<Void> asyncSet(E newValue)

Deprecated.

Atomically sets the given value.

Parameters:

newValue - the new value

asyncGetAndSet

ICompletableFuture<E> asyncGetAndSet(E newValue)

Deprecated.

Gets the value and sets the new value.

Parameters:

newValue - the new value.

Returns:

the old value.

asyncSetAndGet

ICompletableFuture<E> asyncSetAndGet(E update)

Deprecated. will be removed from Hazelcast 3.4 since it doesn't really serve a purpose.

Sets and gets the value.

Parameters:

update - the new value

Returns:

the new value

asyncIsNull

asyncContains

ICompletableFuture<Boolean> asyncContains(E value)

Deprecated.

Checks if the reference contains the value.

Parameters:

value - the value to check (is allowed to be null).

Returns:

true if the value is found, false otherwise.

asyncAlter

ICompletableFuture<Void> asyncAlter(IFunction<E,E> function)

Deprecated.

the old value

Throws:

IllegalArgumentException - if function is null.

asyncApply

<R> ICompletableFuture<R> asyncApply(IFunction<E,R> function)

Deprecated.

Applies a function on the value, the actual stored value will not change.

Parameters:

function - the function
