Class StandardURIResolver

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

All Implemented Interfaces:

URIResolver

public class StandardURIResolver
extends Object
implements URIResolver

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.
