All Implemented Interfaces:
Result, Receiver
Direct Known Subclasses:
AllElementValidator, ComplexContentValidator, EmptyContentValidator, SimpleContentValidator
public abstract class AttributeValidator extends ContentValidator
This class is an abstract superclass for all the receivers that do element content validation. Since all kinds of element content can be associated with attributes, the attribute validation is handled at this level.

  • Constructor Details

    • AttributeValidator

      public AttributeValidator(Receiver next)
      Create an AttributeValidator
      Parameters:
      next - the next receiver in the pipeline

  • Method Details

    • setAttributeGroup

      public void setAttributeGroup(AttributeGroupDecl attributeGroup)
      Identify the set of attributes permitted by the complex type being validated. This is called during initialization of the AttributeValidator. It is not called if the type is a simple type; in such cases any attribute is an error, except for the xsi: attributes permitted on all elements.
      Parameters:
      attributeGroup - the set of attributes declared for this complex type
      Throws:
      MissingComponentException - if an unresolved reference is found

    • validateAttributes

      public AttributeMap validateAttributes(AttributeMap in, List<NamespaceBinding> additionalNamespaces) throws XPathException
      Handle the attributes
      Overrides:
      validateAttributes in class ContentValidator
      Parameters:
      in - the supplied attribute collection
      additionalNamespaces - a mutable list to which additional namespace bindings can be added in the event that validation of attributes requires new namespaces (to support fixed or default values of QName-valued attributes)
      Returns:
      the validated attribute collection
      Throws:
      XPathException

    • getMostRecentAttributeType

      public SimpleType getMostRecentAttributeType()
      Get the SimpleType used for validating the most recent attribute, if any
      Returns:
      the SimpleType of the most recent attribute

    • startElement

      public void startElement(NodeName elemName, SchemaType type, AttributeMap attributes, NamespaceMap namespaces, Location location, int properties) throws XPathException
      Handle the start tag for a child element of the element being validated
      Specified by:
      startElement in interface Receiver
      Overrides:
      startElement in class ContentValidator
      Parameters:
      elemName - the name of the element.
      type - the type annotation of the element.
      attributes - the attributes of this element
      namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements
      location - an object providing information about the module, line, and column where the node originated
      properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption
      Throws:
      XPathException - if an error occurs

    • characters

      public void characters(UnicodeString chars, Location locationId, int properties) throws XPathException
      Handle character data appearing as a child of the element being validated
      Specified by:
      characters in interface Receiver
      Overrides:
      characters in class ProxyReceiver
      Parameters:
      chars - The character content
      locationId - the location of the node in the source, or of the instruction that created it
      properties - Additional properties @throws net.sf.saxon.trans.XPathException
      Throws:
      XPathException - if an error occurs

    • processWildcardTerm

      protected SchemaType processWildcardTerm(Wildcard card, NodeName elementName, Location locationId) throws XPathException
      Process a wildcard term found in complex content or "all" content groups. This method is called when the validator is processing a child element of the relevant group and has established that it matches a wildcard term. The purpose of the method is (a) to determine whether the "processContents=strict" condition is satisfied (that is, there must be a matching global element declaration), and (b) to allocate a childValidator for the child element.
      Parameters:
      card - the Wildcard that has been matched
      elementName - the name of the child element
      locationId - the location of the child element
      Returns:
      the type annotation to be used for the child element
      Throws:
      XPathException - if the content is invalid
