Field Details

singlePathMode

protected boolean singlePathMode

SinglePathMode ensures that only at most a single path is returned. (1) resolution on the template level takes precedence over the data level - no unions of both (2) resolution on the template level to multiple targets raises an exception

reachingRelation

protected Fragment2 reachingRelation

reachingRelationContrib

protected Fragment2 reachingRelationContrib

query

protected org.apache.jena.query.Query query

start

protected org.apache.jena.rdf.model.RDFNode start

parent

protected ResolverTemplate parent
