public interface TupleQueryResultHandler

An interface defining methods related to handling sequences of Solutions.

Method Summary

void	endQueryResult() Indicates the end of a sequence of solutions.
void	handleSolution(BindingSet bindingSet) Handles a solution.
void	startQueryResult(List<String> bindingNames) Indicates the start of a sequence of Solutions.

Method Detail

startQueryResult

void startQueryResult(List<String> bindingNames)
                      throws TupleQueryResultHandlerException

Indicates the start of a sequence of Solutions. The supplied bindingNames are an indication of the values that are in the Solutions. For example, a SeRQL query like select X, Y from {X} P {Y} will have binding names X and Y.

Parameters:

bindingNames - An ordered set of binding names.

Throws:

TupleQueryResultHandlerException

endQueryResult

void endQueryResult()
                    throws TupleQueryResultHandlerException

Indicates the end of a sequence of solutions.

Throws:

TupleQueryResultHandlerException

handleSolution

void handleSolution(BindingSet bindingSet)
                    throws TupleQueryResultHandlerException

Handles a solution.
