      a String containing the generated XSD.
      Throws:
      IllegalArgumentException - if the XSD could not be generated.
    • generate

      public String generate(List types, Map namespaceToSchemaLocation)
      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.
      Throws:
      IllegalArgumentException - if the XSD could not be generated.
