Constructor Summary

DAMLInstanceImpl(java.lang.String uri, DAMLModel store, DAMLVocabulary vocabulary)
Constructor, takes the URI for this instance, and the underlying model it will be attached to.

DAMLInstanceImpl(java.lang.String namespace, java.lang.String name, DAMLModel store, DAMLVocabulary vocabulary)
Constructor, takes the name and namespace for this instance, and the underlying model it will be attached to.

Method Summary

PropertyAccessor	accessProperty(Property property) Answer a property accessor for a user defined property.
java.util.Iterator	getEquivalentValues() Answer an iterator over all of the DAML objects that are equivalent to this instance, which will be the union of daml:equivalentTo and daml:sameIndividualAs.
java.util.Iterator	getSameInstances() Return an iterator over all of the instances that are the same as this one, by generating the transitive closure over the daml:samePropertyAs property.
PropertyAccessor	prop_sameIndividualAs() Property accessor for daml:sameIndividualAs property on a DAML instance.

Constructor Detail

DAMLInstanceImpl

public DAMLInstanceImpl(java.lang.String namespace,
                        java.lang.String name,
                        DAMLModel store,
                        DAMLVocabulary vocabulary)

Constructor, takes the name and namespace for this instance, and the underlying model it will be attached to. Note that it is assumed that the RDF store will contain a statement of the class to which this instance belongs.

Parameters:

namespace - The namespace the instance inhabits, or null

name - The name of the instance

store - The RDF store that contains the RDF statements defining the properties of the instance

vocabulary - Reference to the DAML vocabulary used by this instance.

DAMLInstanceImpl

public DAMLInstanceImpl(java.lang.String uri,
                        DAMLModel store,
                        DAMLVocabulary vocabulary)

Constructor, takes the URI for this instance, and the underlying model it will be attached to. Note that it is assumed that the RDF store will contain a statement of the class to which this instance belongs.

Parameters:

uri - The URI of the instance

store - The RDF store that contains the RDF statements defining the properties of the instance

vocabulary - Reference to the DAML vocabulary used by this instance.

Method Detail

prop_sameIndividualAs

public PropertyAccessor prop_sameIndividualAs()

Property accessor for daml:sameIndividualAs property on a DAML instance.

Specified by:

prop_sameIndividualAs in interface DAMLInstance

Returns:

a property accessor

getSameInstances

public java.util.Iterator getSameInstances()

Return an iterator over all of the instances that are the same as this one, by generating the transitive closure over the daml:samePropertyAs property.

Specified by:

getSameInstances in interface DAMLInstance

Returns:

an iterator whose values will all be DAMLInstance objects

getEquivalentValues

public java.util.Iterator getEquivalentValues()

Answer an iterator over all of the DAML objects that are equivalent to this instance, which will be the union of daml:equivalentTo and daml:sameIndividualAs.

Specified by:

getEquivalentValues in interface DAMLInstance

Overrides:

getEquivalentValues in class DAMLCommonImpl

Returns:

an iterator ranging over every equivalent DAML instance - each value of the iteration should be a DAMLInstance object.

accessProperty

public PropertyAccessor accessProperty(Property property)

Answer a property accessor for a user defined property. TODO: think of a better name for this method!

Specified by:

accessProperty in interface DAMLInstance

Parameters:

property - An RDF or DAML property

Returns:

a property accessor, that simplifies some of the basic operations of a given property on a given object
