Constructor Detail

SPARQLHTMLWriter

public SPARQLHTMLWriter(java.io.OutputStream out)

Constructor for SPARQLHTMLWriter.

Parameters:

out - a OutputStream object.

Method Detail

getTupleQueryResultFormat

public org.openrdf.query.resultio.TupleQueryResultFormat getTupleQueryResultFormat()

getTupleQueryResultFormat

Specified by:

getTupleQueryResultFormat in interface org.openrdf.query.resultio.TupleQueryResultWriter

Returns:

a TupleQueryResultFormat object.

startQueryResult

public void startQueryResult(java.util.List<java.lang.String> bindingNames)
                      throws org.openrdf.query.TupleQueryResultHandlerException

Specified by:

startQueryResult in interface org.openrdf.query.TupleQueryResultHandler

Throws:

org.openrdf.query.TupleQueryResultHandlerException

endQueryResult

public void endQueryResult()
                    throws org.openrdf.query.TupleQueryResultHandlerException

endQueryResult

Specified by:

endQueryResult in interface org.openrdf.query.TupleQueryResultHandler

Throws:

org.openrdf.query.TupleQueryResultHandlerException - if any.

handleSolution

public void handleSolution(org.openrdf.query.BindingSet bs)
                    throws org.openrdf.query.TupleQueryResultHandlerException

Specified by:

handleSolution in interface org.openrdf.query.TupleQueryResultHandler

Throws:

org.openrdf.query.TupleQueryResultHandlerException

printValue

public static void printValue(java.lang.Appendable out,
                              org.openrdf.model.Value v)
                       throws java.io.IOException

Render Value as an HTML fragment including markup for the switchable "detail" view that hides literal type URIs for less clutter. See the Prologue for how this works. Also escape newlines to show line breaks accurately. Note that all other markup, e.g. table cell, font, must be wrapped around the call to this method.

Parameters:

out - the PrintStream or Writer (as Appendable) to which to output

v - sesame Value object to display

Throws:

java.io.IOException - if i/o fails

renderLinkedURI

protected static java.lang.String renderLinkedURI(org.openrdf.model.URI uri)

Produce HTML rendering of a URI that is possibly linked data. This initial version just makes links for resources that this repository is obviously capable of resolving (if correctly configured). Eventually it ought to be extended to include resolution URLs for other links that we expect to be resolvable, e.g. ontology URLs, internal repository objects, etc..

Parameters:

uri - a URI object.

Returns:

a String object.
