Interface IOperationQueueDelegate

public interface IOperationQueueDelegate

An IOperationQueueDelegate is used as a delegate for BasicOperationQueue's. The user is allowed to provide any number of IOperationQueueDelegate's for a specific BasicOperationQueue. To register the delegate, use the BasicOperationQueue.addDelegate(IOperationQueueDelegate).

 final IOperationQueue queue = ...;
 final IOperationDelegate delegate = ...;
 queue.addDelegate(delegate);
 

Use the BasicOperationQueue.removeDelegate(IOperationQueueDelegate) method to remove delegates from a desired IOperationQueue. The delegate's onQueueFailed(IOperation) and onQueueFinished(IOperation) methods are executed in a worker thread and therefore cannot update the UI. If the delegate needs to update the UI, this needs to be done in using the nUIController#runOnMDThread(Runnable) method:

 public void onQueueFinished(final IOperation lastOperation) {
        nUIController.runOnMDThread(new Runnable() {
                public void run() {
                        getAppController().closeProgressWindow();
                }
        });
 }

Method Detail

onQueueFailed

void onQueueFailed(IOperation operation)

Notifies this listener that the one IOperation in the queue failed. This only indicates an exception during the execution and is independent from the operation's result code. Furthermore the execution of other IOperations continues according to the queues content.

Parameters:

operation - The failed IOperation.

onQueueFinished

void onQueueFinished(IOperation lastOperation)

Notifies this listener that the queue finished, i.e. there are no more operations to be executed.

Parameters:
