public class DAMLDataInstanceImpl

extends DAMLCommonImpl

implements DAMLDataInstance

A DAML data instance is an instance of a DAML Dataype (compared to an DAML instance which is an instance of a DAML Class; Class and Datatype are disjoint).

Constructor Summary

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

DAMLDataInstanceImpl(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

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.
DatatypeTranslator	getTranslator() Answer the Datatype translator for values encoded by the datatype of this instance.
java.lang.Object	getValue() Answer the value of this instance as a Java object, translated from the serialised RDF representation by the Dataype's translator.
PropertyAccessor	prop_sameIndividualAs() Property accessor for daml:sameIndividualAs property on a DAML instance.
void	setValue(java.lang.Object value) Set the value of this instance to the given Java value, which will be serialised into the RDF graph by the datatype's translator.

Constructor Detail

DAMLDataInstanceImpl

public DAMLDataInstanceImpl(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.

DAMLDataInstanceImpl

public DAMLDataInstanceImpl(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 DAMLDataInstance

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 DAMLDataInstance

Returns:

an iterator whose values will all be DAMLInstance objects

getTranslator

public DatatypeTranslator getTranslator()

Answer the Datatype translator for values encoded by the datatype of this instance.

Specified by:

getTranslator in interface DAMLDataInstance

Returns:

the datatype translator defined by the DAMLDatatype that is the rdf:type of this instance, or null if it is not defined.

getValue

public java.lang.Object getValue()

Answer the value of this instance as a Java object, translated from the serialised RDF representation by the Dataype's translator.

Specified by:

getValue in interface DAMLDataInstance

Returns:

the value of this instance, or null if either the translator or the serialised value is defined

setValue

public void setValue(java.lang.Object value)

Set the value of this instance to the given Java value, which will be serialised into the RDF graph by the datatype's translator.

Specified by:

setValue in interface DAMLDataInstance

Parameters:

value - A Java value whose serialisation will be made the value of this data instance by setting the rdf:value relation.
