Direct Known Subclasses:

OntologyReplicator

public abstract class OntologyProcessor

extends Object

A utility class for processing OWLOntologies in chunks. The progress of the processing can be monitored by attaching a ProgressListener.

Nested Class Summary

protected static class	OntologyProcessor.NullProgressListener Empty progress listener.
protected static interface	OntologyProcessor.ObjectProcessor Processor for loaded objects.
static interface	OntologyProcessor.ProgressListener The interface receiving notification about the progress of the processor.

Field Summary

protected static int	CHUNK_SIZE The size of the chunks for processing.
protected OntologyProcessor.ProgressListener	m_progressListener The progress listener of the processor.

Constructor Summary

OntologyProcessor()
Creates an instance of this class.

Method Summary

protected void	checkInterrupted() Checks whether the thread has been interrupted and throws an exception.
protected void	processElements(Set set, OWLOntology ontology, int loadFlag, OntologyProcessor.ObjectProcessor objectProcessor, int progressPhase) Loads and processes elements from the given set in chunks.
void	setProgressListener(OntologyProcessor.ProgressListener progressListener) Registers a progress listener.

Method Detail

setProgressListener

public void setProgressListener(OntologyProcessor.ProgressListener progressListener)

Registers a progress listener.

Parameters:

progressListener - the listener for processor progress

processElements

protected void processElements(Set set,
                               OWLOntology ontology,
                               int loadFlag,
                               OntologyProcessor.ObjectProcessor objectProcessor,
                               int progressPhase)
                        throws OWLException,
                               InterruptedException

Loads and processes elements from the given set in chunks.

Parameters:

set - the original set of objects

ontology - the OWLOntology that loads elements (may be null - loading is then not done)

loadFlag - the flag specifying which information should be loaded

objectProcessor - receives objects to be processed

progressPhase - the phase of the replication

Throws:

OWLException - thrown if there is an error

InterruptedException - thrown if the replicator has been interrupted

checkInterrupted

protected void checkInterrupted()
                         throws InterruptedException

Checks whether the thread has been interrupted and throws an exception.

Throws:

InterruptedException - thrown if the replicator has been interrupted
