extends java.lang.Object
implements OWLReasoner

Author: Matthew Horridge

Acts as mediator with an OWLReasoner. The mediator provides several useful layers of client implementation functionality and insulation on top of basic reasoner functionality. For example, autoloading and unloading of imports, silent undefined entity handling etc.

Method Detail

getKernel

public OWLReasoner getKernel()

Gets the real reasoner that this mediator wraps

isSilentUndefinedEntityHandlingEnabled

public boolean isSilentUndefinedEntityHandlingEnabled()

Determines if undefined entities are handled silently. An undefined entity is a class, property or individual which the reasoner does not know about. If asks are performed on undefined entities then there are two possibilities: 1) An UndefinedEntityException is thrown, or 2) The undefined entity is handled silently and a "null" response is returned.

Generally speaking, if silent undefined entity handling is enabled then all asks operations which return Sets and Maps will return empty Sets and empty Maps if the asks request references an undefined entity. For example, if getSubClasses asks for the subclasses of an undefined entity then an empty Set will be returned. Most methods which have boolean return values will return false, for example isType will return false if the individual is undefined, or the class description which is the type references an undefined entity. The exception to this is the isSatisfiable asks request which will return the value set by setUndefinedClassesSatisfiable.

Returns:

true if silent undefined entity handling is enabled, otherwise false. If undefined entity handling is not enabled then asks requests that reference undefined entities will most likely throw UndefinedEntityExceptions.

setSilentUndefinedEntityHandling

public void setSilentUndefinedEntityHandling(boolean silentUndefinedEntityHandling)

Sets the undefined entity handling behaviour.

Parameters:

silentUndefinedEntityHandling - true if undefined entities should be handled silently, otherwise false.

isUndefinedClassesSatisfiable

public boolean isUndefinedClassesSatisfiable()

If an isSatisfiable ask is performed on an undefined class then the return value of this method will be equal to the return value of the asks request.

Returns:

true if undefined classes should be regarded as being satisfiable, false if undefined classes should be regarded as being unsatisfiable.
