Class SchemaDVFactory

java.lang.Object
org.apache.jena.ext.xerces.impl.dv.SchemaDVFactory
Direct Known Subclasses:
BaseDVFactory, BaseSchemaDVFactory

public abstract class SchemaDVFactory extends 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. @xerces.internal

  • Method Details

    • getInstance

      public static final SchemaDVFactory getInstance()
      Get a default instance of SchemaDVFactory implementation.
      Returns:
      an instance of SchemaDVFactory implementation
    • getBuiltInType

      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
    • getBuiltInTypes

      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
    • createTypeRestriction

      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
    • createTypeList

      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
    • createTypeUnion

      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
