Constructor Detail

SimpleConfiguration

public SimpleConfiguration()

SimpleConfiguration

public SimpleConfiguration(ReasonerProgressMonitor progressMonitor)

Parameters:

progressMonitor - the progress monitor to use

SimpleConfiguration

public SimpleConfiguration(ReasonerProgressMonitor progressMonitor,
                   long timeOut)

Parameters:

progressMonitor - the progress monitor to use

timeOut - the timeout in milliseconds

SimpleConfiguration

public SimpleConfiguration(ReasonerProgressMonitor progressMonitor,
                   FreshEntityPolicy freshEntityPolicy,
                   long timeOut,
                   IndividualNodeSetPolicy individualNodeSetPolicy)

Parameters:

progressMonitor - the progress monitor to use

freshEntityPolicy - the policy for fresh entities

timeOut - the timeout in milliseconds

individualNodeSetPolicy - the policy for individual nodes

SimpleConfiguration

public SimpleConfiguration(FreshEntityPolicy freshEntityPolicy,
                   long timeOut)

Parameters:

freshEntityPolicy - the policy for fresh entities

timeOut - the timeout in milliseconds

SimpleConfiguration

public SimpleConfiguration(long timeOut)

Parameters:

timeOut - the timeout in milliseconds

Method Detail

getProgressMonitor

public ReasonerProgressMonitor getProgressMonitor()

Description copied from interface: OWLReasonerConfiguration

Gets a progress monitor that the reasoner may update with information about the progress of its reasoning process.

Specified by:

getProgressMonitor in interface OWLReasonerConfiguration

Returns:

A progress monitor. By default this returns NullReasonerProgressMonitor

getTimeOut

public long getTimeOut()

Description copied from interface: OWLReasonerConfiguration

Gets the timeout in milliseconds for basic single reasoner operations (satisfiability check time out). If the value is equal to Long.MAX_VALUE then this means that the reasoner should never time out.

The reasoner will monitor the elapsed time during a satisfiability check (attempt to build a model for example) and if the elapsed time exceeds the timeout then it will abort the test as soon as possible and terminate all reasoning. A TimeOutException will be thrown in the thread that invoked the last reasoner operation.

Note that this is not a timeout for method calls such as "getSubClasses", which may involve many satisfiability (or other basic reasoning task) checks, the sum of which may well exceed the timeout.

Specified by:

getTimeOut in interface OWLReasonerConfiguration

Returns:

The time out in milliseconds. By default this is set to the value of Long.MAX_VALUE, which means the reasoner SHOULD NOT timeout.

getFreshEntityPolicy

public FreshEntityPolicy getFreshEntityPolicy()

Description copied from interface: OWLReasonerConfiguration

Gets the fresh entity policy that should be used. By default this is set to FreshEntityPolicy.ALLOW.

Specified by:

getFreshEntityPolicy in interface OWLReasonerConfiguration

Returns:

The fresh entity policy.

getIndividualNodeSetPolicy

public IndividualNodeSetPolicy getIndividualNodeSetPolicy()

Description copied from interface: OWLReasonerConfiguration

Gets the IndividualNodeSetPolicy which determines how NodeSets of named individuals are returned from the reasoner.

Specified by:

getIndividualNodeSetPolicy in interface OWLReasonerConfiguration

Returns:

The IndividualNodeSetPolicy that should be used. By default the policy is IndividualNodeSetPolicy.BY_NAME i.e. by default individuals that are the same as each other are not grouped into the same node within a node set.
