ExhaustiveSourcePlannerImpl
public class ServiceClauseBasedSourcePlannerImpl extends SourcePlannerBase
This implementation of SourcePlanner does not actually perform query decomposition and source selection but simply assumes queries with SERVICE clauses where, for the moment, all of these SERVICE clauses are of the form "SERVICE uri {...}" (i.e., not "SERVICE var {...}"). Therefore, all that this implementation does is to convert the given query pattern into a logical plan.
