Class GraphNodeWriter

java.lang.Object

org.apache.clerezza.jaxrs.rdf.providers.GraphNodeWriter

All Implemented Interfaces:

javax.ws.rs.ext.MessageBodyWriter<org.apache.clerezza.rdf.utils.GraphNode>

@Service(value=java.lang.Object.class)
 @Property(name="javax.ws.rs",
          boolValue=true)
 @Provider
public class GraphNodeWriter
extends Object
implements javax.ws.rs.ext.MessageBodyWriter<org.apache.clerezza.rdf.utils.GraphNode>

By default this returns a serialization of the context of the GraphNode. The expansion can be widened by using the query parameters xPropObj and xProSubj. These parameters specify property uris (both parameters might be repeated). For the specified properties their objects respectively subjects are expanded as if they were bnodes.
