public class SPARQLHTMLWriter
extends java.lang.Object
implements org.openrdf.query.resultio.TupleQueryResultWriter

Very quick-n-dirty HTML query result output. This is a crime against good HTML but it was hard to justify spending even minimal time on it. XXX FIXME maybe clean this up later. probably not. XXX todo add class tags, odd/even rows and columns, to facilitate better CSS.

Throws:

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

endQueryResult

Specified by:

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.
