Class Q_Query

java.lang.Object
  com.hp.hpl.jena.sparql.lang.rdql.SimpleNode
      com.hp.hpl.jena.sparql.lang.rdql.Q_Query

All Implemented Interfaces:

RDQL_Node

public class Q_Query
extends SimpleNode

Concrete result of parsing a query. This is the top node in the abstract syntax tree generated by the jjtree/javacc grammar. After being created this class builds a Query suitable for execution. After that, this is not used, although many of the syntax tree nodes are used as they implement the interfaces needed by the abstarct query model.

Constructor Summary

Q_Query(int id)

Q_Query(RDQLParser p, int id)

Method Summary

void	rdqlPhase2(Query q)

toString

public java.lang.String toString()

Formats the query from phase 2 in a style that is acceptable to the parser. Note this is NOT guaranteed to be the same as the original string because we may have done optimizations or other rearranging. It should give the same answers on the same dataset.
