An asynchron analyser allows analysing of the data only via a user-induced action event it therefore returns null as the component it wants to present, but a non-null analyser action, which, when activated spawns an own update process.

Asynchron analysers will only react to data change events and will include also non-visible data. The data it acts on build up during the data-change event chain. If the data canvas get visible, the data is queried from it.

Nested Class Summary

private class

JAsynchronAnalyser.AnalyserThread Creates a new thread that takes the components analyser, prepares the data cards to be used in the analyser and processes it on start.

Constructor Detail

JAsynchronAnalyser

protected JAsynchronAnalyser(Map<String,String> prop)

Creates a new period analyser.

Method Detail

init

public void init()

Defaults the anaylser name.

Specified by:

init in interface Initializable

Overrides:

init in class JAbstractAnalyser

getAnalyserAction

public Action getAnalyserAction()

The action starts an analyser thread thast asynchronosly notifies us.

Specified by:

getAnalyserAction in interface DataAnalysing

getAnalyserComponent

protected Component getAnalyserComponent(ActionEvent ae)

Decides, on which component we should display the progress monitor. Per default, the source of the action event is converted as a component and returned. Subclasses, that support multiple analysiztion into the same component may return this component here.

ready

protected abstract void ready(VectorG[] pre,
                              VectorG[] processed)

This method is called, when the data has been processed in the analyser thread. If we do not use these data, but proceed to visualize or metadata, this can be done in this method, as we are not in the event queue. Prior to this method, registered listeners are notified that the DataAnalysing.ANALYSERPROCESS property has changed, if the output was not null.

metaAction

protected abstract boolean metaAction(ActionEvent ae)

This method is called when the action was activated with the meta modifier on. If this method is the only action, we return true here (similar to consume the event). If the analyser should proceed with its task after the meta-action processing, we return false.

Returns:

True, if action was consumed.

getRepresentation

public Component getRepresentation()

Returns null, we have no special representation, only actions.

Specified by:

getRepresentation in interface Displayable
