Method Detail

getTupleQueryResultFormat

public final TupleQueryResultFormat getTupleQueryResultFormat()

Description copied from interface: TupleQueryResultWriter

Gets the query result format that this writer uses.

Specified by:

getTupleQueryResultFormat in interface TupleQueryResultWriter

setPrettyPrint

public void setPrettyPrint(boolean prettyPrint)

Enables/disables addition of indentation characters and newlines in the XML document. By default, pretty-printing is set to true. If set to false, no indentation and newlines are added to the XML document. This method has to be used before writing starts (that is, before #startTupleSet is called).

startQueryResult

public void startQueryResult(List<String> bindingNames)
                      throws TupleQueryResultHandlerException

Description copied from interface: TupleQueryResultHandler

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.

Specified by:

startQueryResult in interface TupleQueryResultHandler

Parameters:

bindingNames - An ordered set of binding names.

Throws:

TupleQueryResultHandlerException

endQueryResult

public void endQueryResult()
                    throws TupleQueryResultHandlerException

Description copied from interface: TupleQueryResultHandler

Indicates the end of a sequence of solutions.

Specified by:

endQueryResult in interface TupleQueryResultHandler

Throws:

TupleQueryResultHandlerException

handleSolution

public void handleSolution(BindingSet bindingSet)
                    throws TupleQueryResultHandlerException

Description copied from interface: TupleQueryResultHandler

Handles a solution.

Specified by:

handleSolution in interface TupleQueryResultHandler

Throws:

TupleQueryResultHandlerException
