Re: [OWLAPI-developer] Get values from a OWLDataRange

[Dario R. <d4...@gm...>]

Dear Ignazio,

thanks for your reply,

I have to build a parser but I would like to use the library as much as
possible.

For example, I have a datarange with getDataRangeType() that returns:

DataUnionOf(DataOneOf("NULL" ) DataRangeRestriction(xsd:integer
facetRestriction(minInclusive "0"^^xsd:integer)
facetRestriction(maxInclusive "1"^^xsd:integer)) )

If I get the DataRangeType it returns me "DATA_UNION_OF" and it's ok.
Now I expect to have a way to get a Set<OWLDataRange> of 2 elements with
"DataOneOf" and "DataRangeRetriction" but I can't find how to do that. 
The only function that appears to be useful is
"OWLDataRange::getOperands()" but it returns me only an element with the
same value of getDataRangeType().
Have I to get a look to "accept()" and "visit()" functions? It seems
they are not documented in the javadoc.

Thanks.

Dario.
