All Implemented Interfaces:

GraphInterface, SimpleQueryInterface

Direct Known Subclasses:

SquishParser

public class ComplexQuery

extends Graph

implements GraphInterface

An object to encompass a squish query - basically a Graph with some
useful extra bits.

You should not have to deal with it directly: for squish queries use

Graph gr = new Graph(null, uri, Util.RDFXML);
gr.load();
UnionGraph ug=new UnionGraph();
ug.add(gr);

java.sql.ResultSet r=ug.askSquish(query);

or for squish queries with 'from' clauses specifying the urls to query, use

Graph gr = new Graph();
java.sql.ResultSet r=gr.askSquish(query);


and for SQLGraph queries use this:

SQLGraph sq = new SQLGraph();
sq.setdb("jdbc:mysql://127.0.0.1:3306/codepict3?user=mysql&useUnicode=true");
sq.setDriver("com.mysql.jdbc.Driver");
Graph gr = new Graph(null, uri, Util.RDFXML);
gr.load();
sq.add(gr);

java.sql.ResultSet r=sq.askSquish(query);

although you can use ComplexQuery directly:

ComplexQuery cq=(ComplexQuery)SquishParser.parse(query);
cq.getGraphs().addElement(ug);
QE qe=new QE();

java.sql.ResultSet r=qe.executeQuery(cq);
