Class StandardModuleURIResolver

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.

Method Detail

resolve

public StreamSource[] resolve(String moduleURI, String baseURI, String[] locations)
Resolve a module URI and associated location hints.

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. The method may also return null, in which case the system attempts to resolve the URI using the standard module URI resolver.

Throws: net.sf.saxon.trans.XPathException if the module cannot be located
