                comment="A serial controller for conditionally run PR pipelines over corpora.",

public class ConditionalSerialAnalyserController
extends ConditionalSerialController
implements CorpusController, LanguageAnalyser, ControllerAwarePR

This class implements a SerialController that only contains LanguageAnalysers. It has a Corpus and its execute method runs all the analysers in turn over each of the documents in the corpus. This is a copy of the SerialAnalyserController, the only difference being that it inherits from ConditionalSerialController rather than from SerialController which makes it a conditional serial analyser controller.

NOTE: if at the time when execute() is invoked, the document is not null, it is assumed that this controller is invoked from another controller and only this document is processed while the corpus (which must still be non-null) is ignored. Also, if the document is not null, the CorpusAwarePRs are not notified at the beginning, end, or abnormal termination of the pipeline.

If the document is null, all documents in the corpus are processed in sequence and CorpusAwarePRs are notified before the processing of the documents and after all documents have been processed or an abnormal termination occurred.

corpus

protected Corpus corpus

document

protected Document document

The document being processed. This is part of the LanguageAnalyser interface, so this value is only used when the controller is used as a member of another controller.

public ConditionalSerialAnalyserController()

Method Detail

getDocument

public Document getDocument()

Description copied from interface: LanguageAnalyser

Get the document property for this analyser.

Specified by:

getDocument in interface LanguageAnalyser

Returns:

the document

setDocument

@Optional
 @RunTime
 @CreoleParameter
public void setDocument(Document document)

Description copied from interface: LanguageAnalyser

Set the document property for this analyser.

Specified by:

setDocument in interface LanguageAnalyser

Parameters:

document - the document to set

getCorpus

public Corpus getCorpus()

Description copied from interface: CorpusController

Returns the Corpus used by this controller.

Specified by:

getCorpus in interface CorpusController

Specified by:

getCorpus in interface LanguageAnalyser

setCorpus

public void setCorpus(Corpus corpus)

Description copied from interface: CorpusController

Sets the Corpus which contains the data on which the controller is going to run.

Specified by:

setCorpus in interface CorpusController

Specified by:

setCorpus in interface LanguageAnalyser

execute

public void execute()
             throws ExecutionException

Description copied from class: AbstractController

Execute this controller. This implementation takes care of informing any ControllerAwarePRs of the start and end of execution, and delegates to the AbstractController.executeImpl() method to do the real work. Subclasses should override AbstractController.executeImpl() rather than this method.

Specified by:

execute in interface Controller

Specified by:

execute in interface Executable

Overrides:

execute in class AbstractController

Throws:

ExecutionException

executeImpl

protected void executeImpl()
                    throws ExecutionException

Run the Processing Resources in sequence.

Overrides:

executeImpl in class SerialController

Throws:

ExecutionException

add

public void add(ProcessingResource pr)

Overidden from SerialController to only allow LanguageAnalysers as components.

Overrides:

add in class ConditionalSerialController

Parameters:

pr - the PR to be added.

add

public void add(int index,
                ProcessingResource pr)

Overidden from SerialController to only allow LanguageAnalysers as components.

Overrides:

add in class ConditionalSerialController

Parameters:

index - the position for the PR

pr - the PR to be set.

checkLanguageAnalyser

protected void checkLanguageAnalyser(ProcessingResource pr)

Throw an exception if the given processing resource is not a LanguageAnalyser.

setDocToPrs

protected void setDocToPrs(Document doc)

Sets the current document to the memeber PRs

getOffendingPocessingResources

public List<ProcessingResource> getOffendingPocessingResources()
                                                        throws ResourceInstantiationException

Checks whether all the contained PRs have all the required runtime parameters set. Ignores the corpus and document parameters as these will be set at run time.

Overrides:

getOffendingPocessingResources in class AbstractController

Returns:

a List of ProcessingResources that have required parameters with null values if they exist null otherwise.

Throws:

ResourceInstantiationException - if problems occur while inspecting the parameters for one of the resources. These will normally be introspection problems and are usually caused by the lack of a parameter or of the read accessor for a parameter.

resourceUnloaded

public void resourceUnloaded(CreoleEvent e)

Overridden to also clean up the corpus value.

Specified by:

resourceUnloaded in interface CreoleListener

Overrides:

resourceUnloaded in class SerialController

controllerExecutionStarted

public void controllerExecutionStarted(Controller c)
                                throws ExecutionException

Description copied from interface: ControllerAwarePR

Called by a controller containing this PR when the controller begins executing. When this method is called, it is guaranteed that none of the PRs in this controller have yet been executed on this run.

Specified by:

controllerExecutionStarted in interface ControllerAwarePR

Parameters:

c - the Controller that is executing.

Throws:

ExecutionException - if an error occurs that requires the controller to abort its execution.

controllerExecutionFinished

public void controllerExecutionFinished(Controller c)
                                 throws ExecutionException

Description copied from interface: ControllerAwarePR

Called by a controller containing this PR when the controller's execution has completed successfully. When this method is called, it is guaranteed that there will be no more calls to the execute method of any of this controller's PRs in this run.

Specified by:

controllerExecutionFinished in interface ControllerAwarePR

Parameters:

c - the Controller that is executing.

Throws:

ExecutionException - if an error occurs that requires the controller to abort its execution.

controllerExecutionAborted

public void controllerExecutionAborted(Controller c,
                                       Throwable t)
                                throws ExecutionException

Description copied from interface: ControllerAwarePR

Called by a controller containing this PR when the controller's execution has been aborted by an exception thrown by one of the contained PR's execute methods, or by the controller itself. When this method is called, it is guaranteed that there will be no more calls to the execute method of any of this controller's PRs in this run.

Specified by:

controllerExecutionAborted in interface ControllerAwarePR

Parameters:

c - the Controller that is executing.

t - the Throwable that caused the controller to abort. This will be either an ExecutionException, a RuntimeException or an Error.

Throws:

ExecutionException - if an error occurs in this method that requires the controller to abort its execution. This method should not rethrow t, as the controller will do this after informing any other ControllerAware PRs it contains.
