Class SchemaDVFactory

Known Direct Subclasses:
BaseDVFactory, SchemaDVFactoryImpl

public abstract class SchemaDVFactory
extends java.lang.Object

Defines a factory API that enables applications to

1. to get the instance of specified SchemaDVFactory implementation

2. to create/return built-in schema simple types

3. to create user defined simple types.

Implementations of this abstract class can be used to get built-in simple types and create user-defined simle types.

The implementation should store the built-in datatypes in static data, so that they can be shared by multiple parser instance, and multiple threads.

Method Summary

XSSimpleType
createTypeList(String name, String targetNamespace, short finalSet, XSSimpleType itemType, org.apache.xerces.xs.XSObjectList annotations)
Create a new simple type which is derived by list from another simple type.
XSSimpleType
createTypeRestriction(String name, String targetNamespace, short finalSet, XSSimpleType base, org.apache.xerces.xs.XSObjectList annotations)
Create a new simple type which is derived by restriction from another simple type.
XSSimpleType
createTypeUnion(String name, String targetNamespace, short finalSet, XSSimpleType[] memberTypes, org.apache.xerces.xs.XSObjectList annotations)
Create a new simple type which is derived by union from a list of other simple types.
XSSimpleType
getBuiltInType(String name)
Get a built-in simple type of the given name REVISIT: its still not decided within the Schema WG how to define the ur-types and if all simple types should be derived from a complex type, so as of now we ignore the fact that anySimpleType is derived from anyType, and pass 'null' as the base of anySimpleType.
SymbolHash
getBuiltInTypes()
get all built-in simple types, which are stored in a SymbolHash keyed by the name
static SchemaDVFactory
getInstance()
Get a default instance of SchemaDVFactory implementation.
static SchemaDVFactory
getInstance(String factoryClass)
Get an instance of SchemaDVFactory implementation.

Method Details

createTypeList

public XSSimpleType createTypeList(String name,
                                   String targetNamespace,
                                   short finalSet,
                                   XSSimpleType itemType,
                                   org.apache.xerces.xs.XSObjectList annotations)
Create a new simple type which is derived by list from another simple type.

Parameters:
name - name of the new type, could be null
targetNamespace - target namespace of the new type, could be null
finalSet - value of "final"
itemType - item type of the list type

Returns:
the newly created simple type


createTypeRestriction

public XSSimpleType createTypeRestriction(String name,
                                          String targetNamespace,
                                          short finalSet,
                                          XSSimpleType base,
                                          org.apache.xerces.xs.XSObjectList annotations)
Create a new simple type which is derived by restriction from another simple type.

Parameters:
name - name of the new type, could be null
targetNamespace - target namespace of the new type, could be null
finalSet - value of "final"
base - base type of the new type

Returns:
the newly created simple type


createTypeUnion

public XSSimpleType createTypeUnion(String name,
                                    String targetNamespace,
                                    short finalSet,
                                    XSSimpleType[] memberTypes,
                                    org.apache.xerces.xs.XSObjectList annotations)
Create a new simple type which is derived by union from a list of other simple types.

Parameters:
name - name of the new type, could be null
targetNamespace - target namespace of the new type, could be null
finalSet - value of "final"

Returns:
the newly created simple type


getBuiltInType

public XSSimpleType getBuiltInType(String name)
Get a built-in simple type of the given name REVISIT: its still not decided within the Schema WG how to define the ur-types and if all simple types should be derived from a complex type, so as of now we ignore the fact that anySimpleType is derived from anyType, and pass 'null' as the base of anySimpleType. It needs to be changed as per the decision taken.

Parameters:
name - the name of the datatype

Returns:
the datatype validator of the given name


getBuiltInTypes

public SymbolHash getBuiltInTypes()
get all built-in simple types, which are stored in a SymbolHash keyed by the name

Returns:
a SymbolHash which contains all built-in simple types


getInstance

public static final SchemaDVFactory getInstance()
            throws DVFactoryException
Get a default instance of SchemaDVFactory implementation.

Returns:
an instance of SchemaDVFactory implementation

Throws:
DVFactoryException - cannot create an instance of the specified class name or the default class name


getInstance

public static final SchemaDVFactory getInstance(String factoryClass)
            throws DVFactoryException
Get an instance of SchemaDVFactory implementation.

Parameters:
factoryClass - name of the schema factory implementation to instantiate.

Returns:
an instance of SchemaDVFactory implementation

Throws:
DVFactoryException - cannot create an instance of the specified class name or the default class name
