  • Constructor Details

    • TypeAlternative

      public TypeAlternative(EnterpriseConfiguration config, XPathExpression condition, String text)
      Create an TypeAlternative component
      Parameters:
      config - the Saxon configuration
      condition - the compiled XPath expression. May be null if no condition was specified (this is allowed on the last alternative)
      text - the original text of the XPath expression. May be null if no condition was specified (this is allowed on the last alternative)

  • Method Details

    • getCondition

      public XPathExpression getCondition()
      Get the XPath expression used in the test attribute of the alternative. Null represents an absent condition, equivalent to "true()".
      Returns:
      the XPath expression

    • getConditionText

      public String getConditionText()
      Get the original text of the condition.
      Returns:
      the original text of the XPath expression. May be null if no condition was specified

    • setDefaultElementNamespace

      public void setDefaultElementNamespace(NamespaceUri namespace)
      Set the default namespace for elements and types from the static context of the XPath expression
      Parameters:
      namespace - the default namespace for elements and types. The null namespace is represented as ""

    • getDefaultElementNamespace

      public NamespaceUri getDefaultElementNamespace()
      Get the default namesapce for elements and types from the static context of the XPath expression
      Returns:
      the default namespace for elements and types. The null namespace is represented as ""

    • setNamespaceContext

      public void setNamespaceContext(NamespaceResolver resolver)
      Set the namespace context. This is needed to allow the assertion to be serialized, so that the namespace context can be replicated when it is reloaded.
      Parameters:
      resolver - defines the namespace context

    • getNamespaceContext

      public NamespaceResolver getNamespaceContext()
      Get the namespace context for evaluating the XPath expression
      Returns:
      a NamespaceResolver representing the namespace context of the expression

    • setBaseURI

      public void setBaseURI(String baseURI)
      Set the base URI of the XPath expression. This is needed to allow the assertion to be serialized.
      Parameters:
      baseURI - the static base URI of the expression

    • getBaseURI

      public String getBaseURI()
      Get the base URI of the XPath expression
      Returns:
      the static base URI of the expression

    • setTypeReference

      public void setTypeReference(TypeReference type)
      Set the type reference for this alternative
      Parameters:
      type - a reference to the type selected by this alternative

    • getTypeReference

      public TypeReference getTypeReference()
      Get the type reference for this alternative
      Returns:
      the type reference

    • setParameters

      public void setParameters(Map<StructuredQName,XPathVariable> parameters)
      Set the parameters declared for this schema document using the saxon:param extension element
      Parameters:
      parameters - the declared saxon:param parameters in scope for the XPath expression

    • getParameters

      public Map<StructuredQName,XPathVariable> getParameters()
      Get the parameters declared for this schema document using the saxon:param extension element
      Returns:
      the declared saxon:param parameters in scope for the XPath expression

    • getSchemaType

      public SchemaType getSchemaType() throws MissingComponentException
      Get the fixed-up schema type for this alternative
      Returns:
      the schema type
      Throws:
      MissingComponentException

    • fixup

      public boolean fixup(SchemaCompiler compiler) throws SchemaException
      Fixup references from this schema component to others
      Specified by:
      fixup in interface UserSchemaComponent
      Overrides:
      fixup in class SchemaStructure
      Parameters:
      compiler - the SchemaCompiler, used primarily for reporting errors
      Returns:
      true if all references were fixed up successfully, false if dangling references were found
      Throws:
      SchemaException

    • serialize

      public void serialize(SchemaModelSerializer serializer) throws XPathException
      Serialize the schema component
      Parameters:
      serializer - the object responsible for serialization
      Throws:
      XPathException - if a serialization error occur

    • getComponentAsFunction

      public FunctionItem getComponentAsFunction()
      Description copied from interface: SchemaComponent
      Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".
      Specified by:
      getComponentAsFunction in interface SchemaComponent
      Overrides:
      getComponentAsFunction in class SchemaStructure
      Returns:
      the schema component represented as a function from property names to property values.
