Class ValidationStack

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

    public class ValidationStack
    extends ValidatingFilter
    This class manages the receivers that do element content validation. It maintains a stack of Validators, each of which does local element validation of the contents of a single element, adding a new validator to the stack to handle each layer of nesting.

        Set the URI for an unparsed entity in the document.
        Specified by:
        setUnparsedEntity in interface Receiver
        setUnparsedEntity in class ProxyReceiver
        name - The name of the unparsed entity
        uri - The system identifier of the unparsed entity

      • setIsNilled

        public void setIsNilled​(boolean nilled)
        Indicate whether the current element is nilled
        nilled - true if xsi:nil is set

        public void setXsiValidationErrors​(java.util.List<ValidationFailure> errors)
        Supply a list of errors found in attributes in the XSI namespace. This is called immediately before calling startElement on the element containing these erroneous attributes
        errors - the list of errors
      • startElement

        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
      • setInitialValidator

        public void setInitialValidator​(ContentValidator validator)
        Set the initial validator to be used for the outermost element
        validator - the validator to be used for the outermost element being validated

      • setKeepStatistics

        public void setKeepStatistics​(boolean keep)
        Ask that statistics be maintained for the duration of the validation episode. The statistics indicate how often particular schema components (currently, element declarations and types) have been used.
        keep - true if statistics are to be kept, false if not
      • getCoverageStatistics

        public java.util.Map<SchemaComponent,​java.lang.Integer> getCoverageStatistics()
        Get the statistics showing the usage of individual schema components during a validation episode
        a table showing for each component that has been used, the number of times it has been used. If statistics are not being maintained, returns null.
