java.lang.Object

com.hazelcast.client.util.ClientDelegatingFuture<V>

Type Parameters:

V - Value type that user expecting

All Implemented Interfaces:

ICompletableFuture<V>, InternalCompletableFuture<V>, Future<V>

Direct Known Subclasses:

IExecutorDelegatingFuture

public class ClientDelegatingFuture<V>
extends Object
implements InternalCompletableFuture<V>

Client Delegating Future is used to delegate ClientInvocationFuture to user to be used with andThen or get. It converts ClientMessage coming from ClientInvocationFuture to user object

Method Detail

andThenInternal

public <T> void andThenInternal(ExecutionCallback<T> callback,
                                boolean shouldDeserializeData)

Uses internal executor to execute callbacks instead of userExecutor. This method is intended to use by hazelcast internals.

Type Parameters:

T - type of the execution result which is passed to ExecutionCallback.onResponse(V)

Parameters:

callback - callback to execute

shouldDeserializeData - when true execution result is converted to object format before passing to ExecutionCallback.onResponse(V), otherwise execution result will be in Data format

andThen

public void andThen(ExecutionCallback<V> callback)

Description copied from interface: ICompletableFuture

Registers a callback that will run after the future is completed. Please note that there is no ordering guarantee for running multiple callbacks. It is also not guaranteed that the callback will run within the same thread that completes the future.

Specified by:

andThen in interface ICompletableFuture<V>

Parameters:

callback - the callback to execute

andThen

public void andThen(ExecutionCallback<V> callback,
                    Executor executor)

Description copied from interface: ICompletableFuture

Registers a callback that will run with the provided executor after the future is completed. Please note that there is no ordering guarantee for executing multiple callbacks.

Specified by:

andThen in interface ICompletableFuture<V>

Parameters:

callback - the callback to execute

executor - the executor in which the callback will be run

complete

public boolean complete(Object value)

Description copied from interface: InternalCompletableFuture

Completes this future.

Specified by:

complete in interface InternalCompletableFuture<V>

Parameters:

value - the value to complete this future with.

Returns:

true if this invocation caused this InternalCompletableFuture to complete, else false

cancel

public boolean cancel(boolean mayInterruptIfRunning)

Specified by:

cancel in interface Future<V>

isCancelled

public boolean isCancelled()

Specified by:

isCancelled in interface Future<V>

isDone

public final boolean isDone()

Specified by:

isDone in interface Future<V>

get

public V get()
      throws InterruptedException,
             ExecutionException

Specified by:

get in interface Future<V>

Throws:

InterruptedException

ExecutionException

get

public V get(long timeout,
             TimeUnit unit)
      throws InterruptedException,
             ExecutionException,
             TimeoutException

Specified by:

get in interface Future<V>

Throws:

InterruptedException

ExecutionException

TimeoutException

join

public V join()

Description copied from interface: InternalCompletableFuture

Waits for this future to complete.

Specified by:

join in interface InternalCompletableFuture<V>

Returns:

the result.
