Class IdValidator

  • All Implemented Interfaces:
    javax.xml.transform.Result, Receiver

    public class IdValidator
    extends ValidatingFilter
    This class validates that ID elements and attributes have unique values and that IDREF and IDREFS elements and attributes refer to an ID in the same document. The class assumes that these elements and attributes have already been locally validated (so, for example, a element of type ID will not have child elements).

      • IdValidator

        public IdValidator​(Receiver next)
        Create a validator for ID/IDREF constraints
        next - the next receiver in the pipeline

      • startElement

        public void startElement​(NodeName elemName,
                                 SchemaType typeCode,
                                 AttributeMap attributes,
                                 NamespaceMap namespaces,

                          throws XPathException
        Notify the start of an element
        Specified by:
        startElement in interface Receiver
        startElement in class ProxyReceiver
        elemName - the name of the element.
        typeCode - 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
        XPathException - if an error occurs
      • characters

        public void characters​(java.lang.CharSequence chars,
                               Location locationId,
                               int properties)
                        throws XPathException
        Character data
        Specified by:
        characters in interface Receiver
        characters in class ProxyReceiver
        chars - The characters
        locationId - provides information such as line number and system ID.
        properties - Bit significant value. The following bits are defined:
        Disable escaping for this text node
        Output as a CDATA section
        XPathException - if an error occurs
      • usesTypeAnnotations

        public boolean usesTypeAnnotations()
        Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events
        Specified by:
        usesTypeAnnotations in interface Receiver
        usesTypeAnnotations in class ValidatingFilter
        true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation
      • reportValidationError

        protected void reportValidationError​(ValidationFailure err,
                                             Location locationId)
                                      throws XPathException
        Report a validation error
        err - The validation exception
        locationId - identifies the location in the source document or stylesheet/query where the validation error was detected
        ValidationException - if the error is determined to be fatal
