Class AsyncCallbackFuture<T>

java.lang.Object

com.vmware.vapi.bindings.client.AsyncCallback<T>

com.vmware.vapi.bindings.client.AsyncCallbackFuture<T>

All Implemented Interfaces:

java.util.concurrent.Future<T>

public class AsyncCallbackFuture<T>
extends AsyncCallback<T>
implements java.util.concurrent.Future<T>

Utility which is both an asynchronous callback and a future. Could be used to work in a synchronous fashion with an asynchronous operation.

Method Detail

cancel

public boolean cancel(boolean mayInterruptIfRunning)

this implementation doesn't support canceling, so it will always return false.

Specified by:

cancel in interface java.util.concurrent.Future<T>

isCancelled

public boolean isCancelled()

Specified by:

isCancelled in interface java.util.concurrent.Future<T>

isDone

public boolean isDone()

Specified by:

isDone in interface java.util.concurrent.Future<T>

get

public T get()
      throws java.lang.InterruptedException,
             java.util.concurrent.ExecutionException

Specified by:

get in interface java.util.concurrent.Future<T>

Throws:

java.lang.InterruptedException

java.util.concurrent.ExecutionException

get

public T get(long timeout,
             java.util.concurrent.TimeUnit unit)
      throws java.lang.InterruptedException,
             java.util.concurrent.ExecutionException,
             java.util.concurrent.TimeoutException

Specified by:

get in interface java.util.concurrent.Future<T>

Throws:

java.lang.InterruptedException

java.util.concurrent.ExecutionException

java.util.concurrent.TimeoutException

onProgress

public void onProgress(Progress progress)

Description copied from class: AsyncCallback

Reports progress for the operation invocation.

Specified by:

onProgress in class AsyncCallback<T>

Parameters:

progress - progress status of the operation invocation

onResult

public void onResult(T result)

Description copied from class: AsyncCallback

Completes the invocation with a result object.

Specified by:

onResult in class AsyncCallback<T>

Parameters:

result - operation result

onError

public void onError(java.lang.RuntimeException error)

Description copied from class: AsyncCallback

Completes the invocation with an error. The error can be a legal/allowed vAPI error (e.g. descendant of Error) coming from the provider; UnresolvedError if the client bindings do not recognize the vAPI error from the provider; ClientException if the client-side runtime reports an error (e.g. network failure) or some other unchecked exception like IllegalArgumentException if an internal problem occurs in the client-side runtime.

Specified by:

onError in class AsyncCallback<T>

Parameters:

error - operation error
