public class CoServerBindTask<S extends ServerContext>
extends AbstractRemoteTask<S>

This is a special task that actually consists of two coupled tasks. Its purpose is to forward the start of the desired remote task to the target co-server and to route back the RemoteTaskEvents to the originating client.

• The first task (CoServerBindTask) runs as a main-task in the context of the server.
• The second task (BindTask) runs in the CoClientContext as a child-task of the previously mentioned main-task.

The latter BindTask uses a RemoteTaskStartAgent to start the actual desired remote task on the co-server. After having started it, it receives the incoming RemoteTaskEvents and forwards them to its parent main-task. The main-task forwards them further to the waiting client. Note that there is another task running on the client (ClientEDT) which awaits the back coming RemoteTaskEvents. If this client-task is cancelled then the cancel-request is actually forwarded via the server to the remote task running on the co-server.

Method Detail

executeAsync

public final void executeAsync()
                        throws java.lang.Exception

Description copied from class: AbstractAsyncTask

Must be overridden to perform the async part. From within this method you may directly call AbstractAsyncTask.notifyProceeded(Object, int, int, String) in order to notify about task progress. Note: the running task should periodically call AbstractAsyncExecutable.checkCancelled() in order to detect cancellation.

Specified by:

executeAsync in interface AsyncExecutable<S extends ServerContext>

Specified by:

executeAsync in class AbstractAsyncTask<S extends ServerContext>

Throws:

java.lang.Exception
