public java.util.List define(java.io.Reader xsdReader,
                             SchemaResolver schemaResolver)

Define XML Schema as Types. The Types are available through TypeHelper and DataGraph getType() methods.

Parameters:

define

public java.util.List define(javax.xml.transform.Source xsdSource,
                             SchemaResolver schemaResolver)

Description copied from interface: SDOXSDHelper

INTERNAL:

Specified by:

define in interface SDOXSDHelper

Returns:

define

public java.util.List define(java.io.InputStream xsdInputStream,
                             java.lang.String schemaLocation)

Define XML Schema as Types. The Types are available through TypeHelper and DataGraph getType() methods.

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.

Throws:

java.lang.IllegalArgumentException - if the Types could not be defined.

generate

public java.lang.String generate(java.util.List types)

Generate an XML Schema Declaration (XSD) from Types. Same as generate(types, null);

Parameters:

types - a List containing the Types

Returns:

a String containing the generated XSD.

Throws:

java.lang.IllegalArgumentException - if the XSD could not be generated.

generate

public java.lang.String generate(java.util.List types,
                                 java.util.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

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:

java.lang.IllegalArgumentException - if the XSD could not be generated.
