java.lang.Object
  net.sf.saxon.query.StandardModuleURIResolver

All Implemented Interfaces:

Serializable, ModuleURIResolver

public class StandardModuleURIResolver
extends Object
implements ModuleURIResolver

This class is the standard ModuleURIResolver used to implement the "import module" declaration in a Query Prolog. It is used when no user-defined ModuleURIResolver has been specified, or when the user-defined ModuleURIResolver decides to delegate to the standard ModuleURIResolver.

Get the singular instance of this class

resolve

public StreamSource[] resolve(String moduleURI,
                              String baseURI,
                              String[] locations)
                       throws XPathException

Resolve a module URI and associated location hints.

Specified by:

resolve in interface ModuleURIResolver

Parameters:

moduleURI - The module namespace URI of the module to be imported; or null when loading a non-library module.

baseURI - The base URI of the module containing the "import module" declaration; null if no base URI is known

locations - The set of URIs specified in the "at" clause of "import module", which serve as location hints for the module

Returns:

an array of StreamSource objects each identifying the contents of a module to be imported. Each StreamSource must contain a non-null absolute System ID which will be used as the base URI of the imported module, and either an InputSource or a Reader representing the text of the module.

Throws:

XPathException - (error XQST0059) if the module cannot be located
