Method Detail

getLocalName
java.lang.String getLocalName(Type type)
Returns the local name as declared in the XSD.- Parameters:
type
- to return local name for.- Returns:
- the local name as declared in the XSD.
-
getLocalName
java.lang.String getLocalName(Property property)
Returns the local name as declared in the XSD.- Parameters:
property
- to return local name for.- Returns:
- the local name as declared in the XSD.
-
getNamespaceURI
java.lang.String getNamespaceURI(Property property)
Returns the namespace URI as declared in the XSD.- Parameters:
property
- to return namespace URI for.- Returns:
- the namespace URI as declared in the XSD.
-
isAttribute
boolean isAttribute(Property property)
Returns true if the property is declared as an attribute in the XSD. Returns false if not known or for advanced cases. It is possible for both isAttribute and isElement to return false but they will not both return true.- Parameters:
property
- to identify if an attribute.- Returns:
- true if the property is declared as an attribute in the XSD.
-
isElement
boolean isElement(Property property)
Returns true if the property is declared as an element in the XSD. Returns false if not known or for advanced cases. It is possible for both isAttribute and isElement to return false but they will not both return true.- Parameters:
property
- to identify if an element.- Returns:
- true if the property is declared as an element in the XSD.
-
isMixed
boolean isMixed(Type type)
Returns true if the Type is declared to contain mixed content. A DataObject's mixed content values are typically accessed via a Sequence.- Parameters:
type
- to identify if mixed content.- Returns:
- true if the Type is declared to contain mixed content.
-
isXSD
boolean isXSD(Type type)
Indicates if this helper contains XSD information for the specified type.- Parameters:
type
- the type.- Returns:
- true if this helper contains XSD information for the specified type.
-
getGlobalProperty
Property getGlobalProperty(java.lang.String uri, java.lang.String propertyName, boolean isElement)
Returns the Property defined by the named global element or attribute in the targetNamespace uri, or null if not found.- Parameters:
uri
- The uri of the targetNamespace.propertyName
- The name of the global property.isElement
- is true for global elements, false for global attributes.- Returns:
- the Property defined by the named global element or attribute in the targetNamespace uri, or null if not found.
-
getAppinfo
java.lang.String getAppinfo(Type type, java.lang.String source)
Return the appinfo declared for this Type and source. The appinfo start and end tags and content are returned. The xml namespace context is preserved in the appinfo element. If more than one appinfo with the same source is declared on the same Type their contents are concatenated.- Parameters:
type
- the type with the appinfo declarationsource
- the source of the appinfo declaration.- Returns:
- the appinfo declared for this Type and source.
-
getAppinfo
java.lang.String getAppinfo(Property property, java.lang.String source)
Return the content of the appinfo declared for this Property and source. If the property is defined by ref= the appinfo of the referenced element or attribute is included. The appinfo start and end tags and content are returned. The xml namespace context is preserved in the appinfo element. If more than one appinfo with the same source is declared on the same Type their contents are concatenated.- Parameters:
property
- the Property with the appinfo declarationsource
- the source of the appinfo declaration.- Returns:
- the appinfo declared for this Property and source.
-
define
java.util.List define(java.lang.String xsd)
Define the XML Schema as Types. The Types are available through TypeHelper and DataGraph getType() methods. Same as define(new StringReader(xsd), null)- Parameters:
xsd
- the XML Schema.- Returns:
- the defined Types.
- Throws:
java.lang.IllegalArgumentException
- if the Types could not be defined.
-
define
java.util.List define(java.io.Reader xsdReader, java.lang.String schemaLocation)
Define XML Schema as Types. The Types are available through TypeHelper and DataGraph getType() methods.- Parameters:
xsdReader
- reader 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.
-
define
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
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
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 TypesnamespaceToSchemaLocation
- 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.
