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<DocumentPrintNode>

Throws:

JobException - in case of initialization failure

preWork

protected void preWork()
                throws Throwable

Description copied from class: NodeWorker

This method is called immediately before NodeWorker.work() will be called.

Use this method e.g. to initialize objects on the same Thread on which NodeWorker.work() is executed in contrast to NodeWorker.initialize() which is called on a different Thread.

Overrides:

preWork in class NodeWorker<DocumentPrintNode>

Throws:

Throwable - in case of preparation errors

See Also:

NodeWorker.initialize(), NodeWorker.work(), NodeWorker.postWork()

work

protected void work(Stream stream)
             throws Throwable

Description copied from class: StreamWorker

Implement this method in order to work on a single stream.

Specified by:

work in class StreamWorker<DocumentPrintNode>

Parameters:

stream - the Stream to work on

Throws:

Throwable - in case of processing failure

postWork

protected void postWork()
                 throws Throwable

Description copied from class: NodeWorker

This method is called immediately after NodeWorker.work() has returned. It will be called even when a failure in NodeWorker.work() has occured.

Use this method e.g. to finalize objects on the same Thread on which NodeWorker.work() is executed.

Overrides:

postWork in class NodeWorker<DocumentPrintNode>

Throws:

Throwable - in case of post processing errors

NodeWorker.work(), NodeWorker.preWork()
