Constructor Detail

AbstractProcessingResource

public AbstractProcessingResource()

Method Detail

init

public Resource init()
              throws ResourceInstantiationException

Initialise this resource, and return it.

Specified by:

init in interface Resource

Overrides:

init in class AbstractResource

Throws:

ResourceInstantiationException

execute

public void execute()
             throws ExecutionException

Run the resource. It doesn't make sense not to override this in subclasses so the default implementation signals an exception.

Specified by:

execute in interface Executable

Throws:

ExecutionException

reInit

public void reInit()
            throws ResourceInstantiationException

Reinitialises the processing resource. After calling this method the resource should be in the state it is after calling init. If the resource depends on external resources (such as rules files) then the resource will re-read those resources. If the data used to create the resource has changed since the resource has been created then the resource will change too after calling reInit(). The implementation in this class simply calls init(). This functionality must be overriden by derived classes as necessary.

Specified by:

reInit in interface ProcessingResource

Throws:

ResourceInstantiationException

cleanup

public void cleanup()

should clear all internal data of the resource. Does nothing now

Specified by:

cleanup in interface Resource

Overrides:

cleanup in class AbstractResource

isInterrupted

public boolean isInterrupted()

Checks whether this PR has been interrupted since the last time its execute() method was called.

Specified by:

isInterrupted in interface Executable

interrupt

public void interrupt()

Notifies this PR that it should stop its execution as soon as possible.

Specified by:

interrupt in interface Executable

removeStatusListener

public void removeStatusListener(StatusListener l)

Removes a StatusListener from the list of listeners for this processing resource

addStatusListener

public void addStatusListener(StatusListener l)

Adds a StatusListener to the list of listeners for this processing resource

fireStatusChanged

protected void fireStatusChanged(String e)

Notifies all the StatusListeners of a change of status.

Parameters:

e - the message describing the status change

addProgressListener

public void addProgressListener(ProgressListener l)

Adds a ProgressListener to the list of listeners for this processing resource.

removeProgressListener

public void removeProgressListener(ProgressListener l)

Removes a ProgressListener from the list of listeners for this processing resource.

fireProgressChanged

protected void fireProgressChanged(int e)

Notifies all the ProgressListeners of a progress change event.

Parameters:

e - the new value of execution completion

fireProcessFinished

protected void fireProcessFinished()

Notifies all the ProgressListeners of a progress finished.
