Method Detail

initialize

public void initialize()
                throws JobException

Description copied from class: NodeWorker

This method may be overridden, in order do perform initialization which is necessary before the actual work is started.
Caveat: this method may be called synchronously by the server master thread. Therefore the work done within this call should be kept to an absolute minimum so as not to stall the job acceptor.

Overrides:

initialize in class NodeWorker<ExternalProcessCallNode>

Throws:

JobException

work

public void work()
          throws Exception

Description copied from class: NodeWorker

Implement this method to let the node perform some useful work.

Implementors are free to throw whatever exception they see fit. If any Throwable is thrown from this method, the failure manager is notified about the fatal failure of the whole pipeline.

Specified by:

work in class NodeWorker<ExternalProcessCallNode>

Throws:

Exception

abortNow

public void abortNow()

Description copied from class: NodeWorker

Indicate that any current work should be aborted ASAP. Calling this method will close all input and output bundles and streams, thereby speeding up the termination.

Overrides:

abortNow in class NodeWorker<ExternalProcessCallNode>

getFilename

protected String getFilename()
