Class SAXONFunction

  • All Implemented Interfaces:
    NodeInfo, javax.xml.transform.dom.DOMLocator, javax.xml.transform.Source, javax.xml.transform.SourceLocator, org.w3c.dom.Element, org.w3c.dom.NamedNodeMap, org.w3c.dom.Node, org.xml.sax.Locator
    public class SAXONFunction
extends StyleElement
    Handler for saxon:function and exslt:function elements in stylesheet.
    Attributes:
    name gives the name of the function

    • Method Detail

      • processExtensionElementAttribute

        protected void processExtensionElementAttribute​(int nc)
                                         throws javax.xml.transform.TransformerConfigurationException
        Process the [xsl:]extension-element-prefixes attribute. This overrides the standard method because saxon:function and exslt:function implicitly declare saxon/exslt (respectively) as an extension namespace.
        Overrides:
        processExtensionElementAttribute in class StyleElement
        Parameters:
        nc - the name code of the attribute required (ignored)
        Throws:
        javax.xml.transform.TransformerConfigurationException

      • prepareAttributes

        public void prepareAttributes()
                       throws javax.xml.transform.TransformerConfigurationException
        Description copied from class: StyleElement
        Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass
        Specified by:
        prepareAttributes in class StyleElement
        Throws:
        javax.xml.transform.TransformerConfigurationException

      • mayContainTemplateBody

        public boolean mayContainTemplateBody()
        Determine whether this type of element is allowed to contain a template-body
        Overrides:
        mayContainTemplateBody in class StyleElement
        Returns:
        true: yes, it may contain a template-body

      • validate

        public void validate()
              throws javax.xml.transform.TransformerConfigurationException
        Description copied from class: StyleElement
        Check that the element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.
        Overrides:
        validate in class StyleElement
        Throws:
        javax.xml.transform.TransformerConfigurationException

      • preprocess

        public void preprocess()
                throws javax.xml.transform.TransformerConfigurationException
        Description copied from class: StyleElement
        Default preprocessing method does nothing. It is implemented for those top-level elements that can be evaluated before the source document is available, for example xsl:key, xsl:attribute-set, xsl:template, xsl:locale
        Overrides:
        preprocess in class StyleElement
        Throws:
        javax.xml.transform.TransformerConfigurationException

      • process

        public void process​(Context context)
        Description copied from class: StyleElement
        Process: called to do the real work of this stylesheet element. This method must be implemented in each subclass.
        Specified by:
        process in class StyleElement
        Parameters:
        context - The context in the source XML document, giving access to the current node, the current variables, etc.

      • getProcedure

        public Procedure getProcedure()
        Get associated Procedure (for details of stack frame)

      • getFunctionFingerprint

        public int getFunctionFingerprint()

      • getNthParameter

        public int getNthParameter​(int n)
        Get the name fingerprint of the n'th parameter (starting from 0). Return -1 if there is none such.

      • call

        public Value call​(ParameterSet params,
                  Context context)
           throws javax.xml.transform.TransformerException
        Call this function
        Throws:
        javax.xml.transform.TransformerException
