Interface OInstance

All Superinterfaces:

OResource

public interface OInstance
extends OResource

OInstance (Ontology Instance) represents an instance in the ontology/knowledge base. The interface provides various methods, including and not limited to, obtain a list of classes the instance belongs to, and various methods to add various property values on it.

Method Detail

getOClasses

@Deprecated
Set<OClass> getOClasses(byte closure)

Deprecated.

Gets the set of classes this instance belongs to.

Parameters:

closure - either OntologyConstants.DIRECT_CLOSURE or OntologyConstants.TRANSITIVE_CLOSURE.

Returns:

a set of OClass objects.

getOClasses

Set<OClass> getOClasses(OConstants.Closure closure)

addOClass

void addOClass(OClass theClass)

Make this individual an instance of another class. This does nothing if the individual is already an instance of the given class. Note that this cann lead to inconsistencies, e.g. if this class is disjunct with a class of which the individual is already an instance.

Parameters:

theClass - - the OClass object for the class of which the individual should be an instance.

isInstanceOf

@Deprecated
boolean isInstanceOf(OClass aClass,
                                 byte closure)

Deprecated.

Checks whether the instance is an instance of the provided class.

Parameters:

aClass -

closure - either OntologyConstants.DIRECT_CLOSURE or OntologyConstants.TRANSITIVE_CLOSURE.

Returns:

true, if the instance is indded an instance of the provided class, otherwise - false.

isInstanceOf

boolean isInstanceOf(OClass aClass,
                     OConstants.Closure closure)

setDifferentFrom

void setDifferentFrom(OInstance theInstance)

Sets the instance being different from the provided instance.

getDifferentInstances

Set<OInstance> getDifferentInstances()

Returns a set of OInstance objects which are explicitly specified as being different from the current instance.

Returns:

a Set of OInstances

isDifferentFrom

boolean isDifferentFrom(OInstance theInstance)

Checks whether the instance is different from the given instance

Parameters:

theInstance -

setSameInstanceAs

void setSameInstanceAs(OInstance theIndividual)

Sets the instance being same as the provided instance.

Parameters:

theIndividual -

getSameInstance

Set<OInstance> getSameInstance()

Returns a set of OInstance objects which are explicitly specified as being same as the current instance.

isSameInstanceAs

boolean isSameInstanceAs(OInstance theInstance)

Checks whether the instance is same as the given instance

removeRDFPropertyValue

@Deprecated
void removeRDFPropertyValue(RDFProperty aProperty,
                                        OResource value)

Deprecated.

Remove the provided value for the given property.
