Class XMLSchemaLoader

  • All Implemented Interfaces:
    XSElementDeclHelper, XMLGrammarLoader, XMLComponent, XSLoader, DOMConfiguration
    public class XMLSchemaLoader
extends Object
implements XMLGrammarLoader, XMLComponent, XSElementDeclHelper, XSLoader, DOMConfiguration
    This class implements xni.grammars.XMLGrammarLoader. It also serves as implementation of xs.XSLoader interface and DOMConfiguration interface. This class is designed to interact either with a proxy for a user application which wants to preparse schemas, or with our own Schema validator. It is hoped that none of these "external" classes will therefore need to communicate directly with XSDHandler in future.

    This class only knows how to make XSDHandler do its thing. The caller must ensure that all its properties (schemaLocation, JAXPSchemaSource etc.) have been properly set.

      • resolveDocument

        public static XMLInputSource resolveDocument​(XSDDescription desc,
                                             Hashtable locationPairs,
                                             XMLEntityResolver entityResolver)
                                      throws IOException
        This method tries to resolve location of the given schema. The loader stores the namespace/location pairs in a hashtable (use "" as the namespace of absent namespace). When resolving an entity, loader first tries to find in the hashtable whether there is a value for that namespace, if so, pass that location value to the user-defined entity resolver.
        Parameters:
        desc -
        locationPairs -
        entityResolver -
        Returns:
        the XMLInputSource
        Throws:
        IOException

        Specified by:
        getFeatureDefault in interface XMLComponent
        Parameters:
        featureId - The feature identifier.

      • getConfig

        public DOMConfiguration getConfig()
        Description copied from interface: XSLoader
        The configuration of a document. It maintains a table of recognized parameters. Using the configuration, it is possible to change the behavior of the load methods. The configuration may support the setting of and the retrieval of the following non-boolean parameters defined on the DOMConfiguration interface: error-handler (DOMErrorHandler) and resource-resolver (LSResourceResolver).
        The following list of boolean parameters is defined:
        "validate"
        true
        [required] (default) Validate an XML Schema during loading. If validation errors are found, the error handler is notified.
        false
