    • Finds the appropriate SDOXSDHelperDelegate for the classLoader/application name and delegates work to that implementation of SDOXSDHelper.
    • Define methods defines Types from an XSD.
    • Generate methods an XSD from Types.

        Parameters:
        xsd - the XML Schema.
        Returns:
        the defined Types. Not all of the XML Schema types cause an SDO type to be defined (for example in case of duplicates), the returned list only includes the newly defined types.

      • define

                   String schemaLocation)

        schemaLocation - the URI of the location of the schema, used for processing relative imports and includes. May be null if not used.
        Returns:
        the defined Types. Not all of the XML Schema types cause an SDO type to be defined (for example in case of duplicates), the returned list only includes the newly defined types.

      • define

        public List define​(InputStream xsdInputStream,
                   String schemaLocation)

        Specified by:
        define in interface XSDHelper
        Parameters:
        xsdInputStream - input stream to an XML Schema.
        schemaLocation - the URI of the location of the schema, used for processing relative imports and includes. May be null if not used.
        Returns:
        the defined Types. Not all of the XML Schema types cause an SDO type to be defined (for example in case of duplicates), the returned list only includes the newly defined types.

      • generate

        public String generate​(List types)
        Description copied from interface: XSDHelper
        Generate an XML Schema Declaration (XSD) from Types. Same as generate(types, null);
        Specified by:
        generate in interface XSDHelper
        Parameters:
        types - a List containing the Types
        Returns:
        a String containing the generated XSD.

      • generate

        public String generate​(List types,
                       Map namespaceToSchemaLocation)
        Description copied from interface: XSDHelper
        Generate an XML Schema Declaration (XSD) from Types. Round trip from SDO to XSD to SDO is supported. Round trip from XSD to SDO to XSD is not supported. Use the original schema if one exists instead of generating a new one, as the generated XSD validates a different set of documents than the original XSD. Generating an XSD does not affect the XSDHelper or the Types. The Types must all have the same URI. The result is a String containing the generated XSD. All Types referenced with the same URI will be generated in the XSD and the list will be expanded to include all types generated. Any Types referenced with other URIs will cause imports to be produced as appropriate. Imports will include a schemaLocation if a Map is provided with an entry of the form key=import target namespace, value=schemaLocation
        Specified by:
        generate in interface XSDHelper
        Parameters:
        types - a List containing the Types
        namespaceToSchemaLocation - map of target namespace to schema locations or null
        Returns:
        a String containing the generated XSD.
