                helpURL="http://gate.ac.uk/userguide/sec:developer:cond")
public class ConditionalSerialController
extends SerialController
implements ConditionalController

Execute a list of PRs serially. For each PR a running strategy is stored which decides whether the PR will be run always, never or upon a condition being satisfied. This controller uses AnalyserRunningStrategy objects as running strategies and they only work with LanguageAnalysers so the PRs that are not analysers will get a default "run always" strategy.

ConditionalSerialController

public ConditionalSerialController()

Method Detail

getRunningStrategies

public List<RunningStrategy> getRunningStrategies()

Description copied from interface: ConditionalController

Gets the collection of running strategies for the contained PRs. The iterator of this collection should return the running strategies in sync with the iterator for the getPRs() method of Controller.

Specified by:

getRunningStrategies in interface ConditionalController

Returns:

a Collection object.

add

public void add(int index,
       ProcessingResource pr)

Set a PR at a specified location. The running strategy defaults to run always.

Overrides:

add in class SerialController

Parameters:

index - the position for the PR

pr - the PR to be set.

add

public void add(ProcessingResource pr)

Add a PR to the end of the execution list.

Overrides:

add in class SerialController

Parameters:

pr - the PR to be added.

remove

public ProcessingResource remove(int index)

Overrides:

remove in class SerialController

remove

public boolean remove(ProcessingResource pr)

Overrides:

remove in class SerialController

setRunningStrategy

public void setRunningStrategy(int index,
                      AnalyserRunningStrategy strategy)

setRunningStrategies

public void setRunningStrategies(Collection<RunningStrategy> strategies)

Populates this controller with the appropiate running strategies from a collection of running strategies (optional operation). Controllers that are serializable must implement this method needed by GATE to restore their contents.

Specified by:

setRunningStrategies in interface ConditionalController

Throws:

UnsupportedOperationException - if the setPRs method is not supported by this controller.

runComponent

protected void runComponent(int componentIndex)
                     throws ExecutionException

Executes a ProcessingResource.

Overrides:

runComponent in class SerialController

Throws:

ExecutionException

cleanup

public void cleanup()

Cleans the internal data and prepares this object to be collected

Specified by:

cleanup in interface Resource

Overrides:

cleanup in class SerialController

duplicate

public Resource duplicate(Factory.DuplicationContext ctx)
                   throws ResourceInstantiationException

Custom duplication method for conditional controllers to handle duplicating the running strategies.

Specified by:

duplicate in interface CustomDuplication

Overrides:

duplicate in class SerialController

Parameters:

ctx - the current duplication context. If an implementation of this method needs to duplicate any other resources as part of the custom duplication process it should pass this context back to the two-argument form of Factory.duplicate rather than using the single-argument form.

Returns:

an independent copy of this resource.

Throws:

ResourceInstantiationException
