Class Overview

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.

Public Methods
abstract XSSimpleType createTypeList(String name, String targetNamespace, short finalSet, XSSimpleType itemType, XSObjectList annotations)
Create a new simple type which is derived by list from another simple type.
abstract XSSimpleType createTypeRestriction(String name, String targetNamespace, short finalSet, XSSimpleType base, XSObjectList annotations)
Create a new simple type which is derived by restriction from another simple type.
abstract XSSimpleType createTypeUnion(String name, String targetNamespace, short finalSet, XSSimpleType[] memberTypes, XSObjectList annotations)
Create a new simple type which is derived by union from a list of other simple types.
abstract 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.
abstract SymbolHash getBuiltInTypes()
get all built-in simple types, which are stored in a SymbolHash keyed by the name
synchronized final static SchemaDVFactory getInstance()
Get a default instance of SchemaDVFactory implementation.
synchronized final static SchemaDVFactory getInstance(String factoryClass)
Get an instance of SchemaDVFactory implementation.

Public Methods

public abstract XSSimpleType createTypeList (String name, String targetNamespace, short finalSet, XSSimpleType itemType, 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
annotations set of annotations
Returns
  • the newly created simple type

public abstract XSSimpleType createTypeRestriction (String name, String targetNamespace, short finalSet, XSSimpleType base, 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
annotations set of annotations
Returns
  • the newly created simple type

public abstract XSSimpleType createTypeUnion (String name, String targetNamespace, short finalSet, XSSimpleType[] memberTypes, 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"
memberTypes member types of the union type
annotations set of annotations
Returns
  • the newly created simple type

public abstract 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

public abstract 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

public static final synchronized SchemaDVFactory getInstance ()

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

public static final synchronized SchemaDVFactory getInstance (String factoryClass)

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
