                   java.lang.String namespace)

Constructor used when loading in external user defined XSD types - should only be used by the internals but public scope because the internals spread across multiple packages.

Method Detail

parse

public java.lang.Object parse(java.lang.String lexicalForm)

                       com.hp.hpl.jena.graph.impl.LiteralLabel value2)

Compares two instances of values of the given datatype. This ignores lang tags and defers to the equality function defined by the Xerces package - to be checked.

---

getJavaClass

public java.lang.Class getJavaClass()

If this datatype is used as the cannonical representation for a particular java datatype then return that java type, otherwise returns null.

---

extendedTypeDefinition

public java.lang.Object extendedTypeDefinition()

Returns the Xerces datatype representation for this type, this is an XSSimpleType, in fact an XSSimpleTypeDecl.

---

loadUserDefined

public static java.util.List loadUserDefined(java.lang.String uri,
                                             java.io.Reader reader,
                                             java.lang.String encoding,

                                      throws com.hp.hpl.jena.datatypes.DatatypeFormatException

Create and register a set of types specified in a user schema file. We use the (illegal) DAML+OIL approach that the uriref of the type is the url of the schema file with fragment ID corresponding the the name of the type.

---

loadUserDefined

public static java.util.List loadUserDefined(java.lang.String uri,
                                             java.lang.String encoding,

                                      throws com.hp.hpl.jena.datatypes.DatatypeFormatException

Create and register a set of types specified in a user schema file. We use the (illegal) DAML+OIL approach that the uriref of the type is the url of the schema file with fragment ID corresponding the the name of the type.

---

loadUserDefined

private static java.util.List loadUserDefined(org.apache.xerces.xni.parser.XMLInputSource source,
                                              com.hp.hpl.jena.datatypes.TypeMapper tm)

public java.lang.Object convertValidatedDataValue(org.apache.xerces.impl.dv.ValidatedInfo validatedInfo)
                                           throws com.hp.hpl.jena.datatypes.DatatypeFormatException

Convert a validated xerces data value into the corresponding java data value. This function is currently the most blatently xerces-version dependent part of this subsystem. In many cases it also involves reparsing data which has already been parsed as part of the validation.

---

parseValidated

public java.lang.Object parseValidated(java.lang.String lexical)

Parse a validated lexical form. Subclasses which use the default parse implementation and are not convered by the explicit convertValidatedData cases should override this.

---

isValidLiteral

public boolean isValidLiteral(com.hp.hpl.jena.graph.impl.LiteralLabel lit)

Test whether the given LiteralLabel is a valid instance of this datatype. This takes into accound typing information as well as lexical form - for example an xsd:string is never considered valid as an xsd:integer (even if it is lexically legal like "1").

---

isBaseTypeCompatible

public boolean isBaseTypeCompatible(com.hp.hpl.jena.graph.impl.LiteralLabel lit)

Test if the given typed value is in the right partition of the XSD type space. If this test passes then if the typed value has a legal lexical form for this type then it is a legal instance.

---

getFoundingType

private org.apache.xerces.xs.XSTypeDefinition getFoundingType()

Return the most specific type below xsd:anySimpleType that this type is derived from.

---

trimPlus

public static java.lang.String trimPlus(java.lang.String str)

Helper function to return the substring of a validated number string omitting any leading + sign.

---

loadXSDSimpleTypes

public static void loadXSDSimpleTypes(com.hp.hpl.jena.datatypes.TypeMapper tm)

Add all of the XSD pre-defined simple types to the given type mapper registry.

---

main

public static void main(java.lang.String[] args)
