Class XSDatatypeManager

java.lang.Object
  org.dlese.dpc.xml.schema.XSDatatypeManager

public class XSDatatypeManager
extends Object

Provides Map-like interface to XSdatatypes - including built-ins and those datatypes defined by a Schema - used to validate element values within a schema-based document. XSdatatypes validate a value against a defined datatype, whether it is built-in or derived. Built-in data types are supplied by Sun's XSDatatype library, data types specified by a particular schema are derived by extending the built-in types (see deriveType()).

Constructor Detail

XSDatatypeManager

public XSDatatypeManager()

Constructor for the XSDatatypeManager object

XSDatatypeManager

public XSDatatypeManager(GlobalDefMap globalDefMap)

Constructor for the XSDatatypeManager object

Parameters:

globalDefMap - Description of the Parameter

Method Detail

getDerivedTypes

public Map getDerivedTypes()

addDerivedType

public void addDerivedType(com.sun.msv.datatype.xsd.XSDatatype dt)

Adds a derived XSDatatype to the map of derived types

Parameters:

dt - The XSDatatype to be added

getSchemaNSPrefix

public String getSchemaNSPrefix()

getTypeByName

public com.sun.msv.datatype.xsd.XSDatatype getTypeByName(String typeName)

Gets a XSDatatype class used to validate a value against a datatype declared or defined in an XML Schema. XSDatatypes are found either in the derivedTypes map or in the DatatypeFactory (which returns XSDatatyps for built-in types)

Parameters:

typeName - XSDatatype name

Returns:

The XSDatatype object if found, or null

getTypeByNameOLD

public com.sun.msv.datatype.xsd.XSDatatype getTypeByNameOLD(String typeName)

checkValid

public boolean checkValid(String typeName,
                          String value)
                   throws Exception

Checks a value against it's datatype. If a validator (XSDatatype) can't be found for the given typeName, a message is printed and false is returned. This is a pretty weak way of dealing with this problem, since in other cases, an error is thrown to signify an invalid value.

date values are intercepted and handled by MetadataUtils.parseUnionDateType(String)

Parameters:

typeName - Description of the Parameter

value - Description of the Parameter

Returns:

Description of the Return Value

Throws:

Exception - Description of the Exception

checkValid

public boolean checkValid(com.sun.msv.datatype.xsd.XSDatatype dt,
                          String v)
                   throws Exception

validates a String value against an XSDatatype. If the value is not valid an Exception is thrown describing the error.

Parameters:

dt - Description of the Parameter

v - Description of the Parameter

Returns:

Description of the Return Value

Throws:

Exception - Description of the Exception

deriveByUnion

public com.sun.msv.datatype.xsd.XSDatatype deriveByUnion(SimpleType def)
                                                  throws Exception

Description of the Method

Parameters:

def - Description of the Parameter

Returns:

Description of the Return Value

Throws:

Exception - Description of the Exception

main

public static void main(String[] args)
                 throws Exception

The main program for the XSDatatypeManager class

Parameters:

args - The command line arguments

Throws:

Exception - Description of the Exception

destroy

public void destroy()
