Method Detail

addListener

public void addListener(OWLReasonerManagerListener listener)

Description copied from interface: OWLReasonerManager

Adds a listener to this reasoner manager.

Specified by:

addListener in interface OWLReasonerManager

Parameters:

listener - The listener to be added.

removeListener

public void removeListener(OWLReasonerManagerListener listener)

Description copied from interface: OWLReasonerManager

Removes a previously added listener to this manager.

Specified by:

removeListener in interface OWLReasonerManager

Parameters:

listener - The listener to be removed.

getRegisteredReasonerFactories

public java.util.List<OWLReasonerFactory> getRegisteredReasonerFactories()

Description copied from interface: OWLReasonerManager

Gets a list of currently registered reasoner factories.

Specified by:

getRegisteredReasonerFactories in interface OWLReasonerManager

Returns:

A list of reasoner factories.

registerReasonerFactory

public void registerReasonerFactory(OWLReasonerFactory factory)

Description copied from interface: OWLReasonerManager

Registers (adds) a new reasoner factory. An event will be fired to indicate that a reasoner factory has be registered.

Specified by:

registerReasonerFactory in interface OWLReasonerManager

Parameters:

factory - The factory to be registered.

unregisterReasonerFactory

public void unregisterReasonerFactory(OWLReasonerFactory factory)

Description copied from interface: OWLReasonerManager

Unregisters (removes) a previously registerd reasoner factory. An event will be fired to indicated that a reasoner factory has been unregistered.

Specified by:

unregisterReasonerFactory in interface OWLReasonerManager

Parameters:

factory - The factory to be unregisterd.

setReasonerFactory

public void setReasonerFactory(OWLReasonerFactory factory)
                        throws OWLReasonerException

Description copied from interface: OWLReasonerManager

Sets the current reasoner factory. This will result in an event being fired to indicate the reasoner factory has changed. The currently cached reasoner will be disposed of an a new reasoner that is instantiated by the specified reasoner factory will be cached as the current reasoner.

Specified by:

setReasonerFactory in interface OWLReasonerManager

Parameters:

factory - The reasoner factory that should be set as the current factory. Note that a runtime exception will be thrown if the specified reasoner factory is not a registered reasoner factory.

Throws:

OWLReasonerException - if there was a problem in disposing of the currently cached reasoner.

getReasonerFactory

public OWLReasonerFactory getReasonerFactory()

Description copied from interface: OWLReasonerManager

Gets the current reasoner factory.

Specified by:

getReasonerFactory in interface OWLReasonerManager

Returns:

The current reasoner factory which will not be null

getReasoner

public OWLReasoner getReasoner()

Description copied from interface: OWLReasonerManager

Gets the currently cached reasoner. If the reasoner factory has changed since this method call then a new instance of a reasoner will be created and returned.

Specified by:

getReasoner in interface OWLReasonerManager

Returns:

The currently cached reasoner that was created (first) from the current reasoner factory. This will not be null.

createReasoner

public OWLReasoner createReasoner()

Description copied from interface: OWLReasonerManager

Creates a new instance of a reasoner using the current reasoner factory.

Specified by:

createReasoner in interface OWLReasonerManager

Returns:

A new instance of a reasoner created with the current reasoner factory.

fireReasonerFactoryAdded

protected void fireReasonerFactoryAdded()

fireReasonerFactoryRemoved

protected void fireReasonerFactoryRemoved()

fireReasonerFactoryChanged

protected void fireReasonerFactoryChanged()
