Class StandardURIResolver

java.lang.Object
  net.sf.saxon.lib.StandardURIResolver

All Implemented Interfaces:

Serializable, URIResolver, NonDelegatingURIResolver

Direct Known Subclasses:

PTreeURIResolver, XomUriResolver

public class StandardURIResolver
extends Object
implements NonDelegatingURIResolver, Serializable

This class provides the service of converting a URI into an InputSource. It is used to get stylesheet modules referenced by xsl:import and xsl:include, and source documents referenced by the document() function. The standard version handles anything that the java URL class will handle. You can write a subclass to handle other kinds of URI, e.g. references to things in a database.

Constructor Detail

StandardURIResolver

public StandardURIResolver()

Deprecated. since 8.7

Create a StandardURIResolver, with no reference to a Configuration. This constructor is not used internally by Saxon, but it may be used by user-written application code. It is deprecated because the StandardURIResolver works best when the Configuration is known.

StandardURIResolver

public StandardURIResolver(Configuration config)

Create a StandardURIResolver, with a reference to a Configuration

Parameters:

config - The Configuration object. This is used to get a SAX Parser for a source XML document

Method Detail

setRecognizeQueryParameters

public void setRecognizeQueryParameters(boolean recognize)

Indicate that query parameters (such as validation=strict) are to be recognized

Parameters:

recognize - Set to true if query parameters in the URI are to be recognized and acted upon. The default (for compatibility and interoperability reasons) is false.

queryParametersAreRecognized

public boolean queryParametersAreRecognized()

Determine whether query parameters (such as validation=strict) are to be recognized

Returns:

true if query parameters are recognized and interpreted by Saxon.

getPlatform

protected Platform getPlatform()

Get the relevant platform

Returns:

the platform

setConfiguration

public void setConfiguration(Configuration config)

Set the configuration

Parameters:

config - the configuration

getConfiguration

public Configuration getConfiguration()

Get the configuration if available

Returns:

the configuration

resolve

public Source resolve(String href,
                      String base)
               throws XPathException

Resolve a URI

Specified by:

resolve in interface URIResolver

Parameters:

href - The relative or absolute URI. May be an empty string. May contain a fragment identifier starting with "#", which must be the value of an ID attribute in the referenced XML document.

base - The base URI that should be used. May be null if uri is absolute.

Returns:

a Source object representing an XML document

Throws:

XPathException

getPTreeSource

protected Source getPTreeSource(String href,
                                String base)
                         throws XPathException

Handle a PTree source file (Saxon-EE only)

Parameters:

href - the relative URI

base - the base URI

Returns:

the new Source object

Throws:

XPathException

setSAXInputSource

protected void setSAXInputSource(SAXSource source,
                                 String uriString)

Set the InputSource part of the returned SAXSource. This is done in a separate method to allow subclassing. The default implementation simply places the URI in the InputSource, allowing the XML parser to take responsibility for the dereferencing. A subclass may choose to dereference the URI at this point an place an InputStream in the SAXSource.

Parameters:

source - the SAXSource being initialized

uriString - the absolute (resolved) URI to be used
