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

Method Detail

prop_sameIndividualAs

public PropertyAccessor prop_sameIndividualAs()

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

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.

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.

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.

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
