Constructor Detail

StandardOutputResolver

public StandardOutputResolver()
Method Detail

getInstance

public static StandardOutputResolver getInstance()
Get a singular instance

Returns:
the singleton instance of the class

resolve

public Result resolve(String href,
                      String base)
               throws XPathException
Resolve an output URI

Specified by:
resolve in interface OutputURIResolver
Parameters:
href - The relative URI of the output document. This corresponds to the href attribute of the xsl:result-document instruction.
base - The base URI that should be used. This is the base output URI, normally the URI of the principal output file.
Returns:
a Result object representing the destination for the XML document
Throws:
XPathException

makeOutputFile

public static Result makeOutputFile(URI absoluteURI)
                             throws XPathException
Create an output file (unless it already exists) and return a reference to it as a Result object

Parameters:
absoluteURI - the URI of the output file (which should use the "file" scheme
Returns:
a Result object referencing this output file
Throws:
XPathException

close

public void close(Result result)
           throws XPathException
Signal completion of the result document. This method is called by the system when the result document has been successfully written. It allows the resolver to perform tidy-up actions such as closing output streams, or firing off processes that take this result tree as input. Note that the OutputURIResolver is stateless, so the original href is supplied to identify the document that has been completed.

Specified by:
close in interface OutputURIResolver
Parameters:
result - The result object returned by the previous call of resolve()
Throws:
XPathException
