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 instances 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.

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

getEquivalentValues

public java.util.Iterator getEquivalentValues()

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

Specified by:

getEquivalentValues in interface DAMLCommon

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!

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
