All Implemented Interfaces:
graphql.language.NodeVisitor
public class TransformExpandShorthands extends NodeVisitorPrefixesBase
Expands:
  • @prefix
  • @graph
  • @service
  • @vocab
  • @reverse
  • @iri
  • @source
  • @class
  • @emitRdfKey
Order of resolution:
  1. if vocab is given then build tentative field iri/li>
  2. if iri is given then override the field iri
  3. if class is given then use the field iri to build a @source directive
interplay of source and pattern: source would filter the sources of a given pattern. Expands 
@rdf(iri: "rdfs:label") @reverse
into 
@pattern(of: "?s rdfs:label ?o", src: 'o', tgt 's'} @emitRdfKey(iri: "rdfs:label", reverse: true)
