        public java.lang.String getDocumentClassName()
        Get the name of a characteristic class, which, if it can be loaded, indicates that the supporting libraries for this object model implementation are available on the classpath
        Specified by:
        getDocumentClassName in interface ExternalObjectModel
        Returns:
        by convention (but not necessarily) the class that implements a document node in the relevant external model
      • getIdentifyingURI

        public java.lang.String getIdentifyingURI()
        Get the URI of the external object model as used in the JAXP factory interfaces for obtaining an XPath implementation
        Specified by:
        getIdentifyingURI in interface ExternalObjectModel
        Returns:
        the URI used to identify this object model in the JAXP XPath factory mechanism.
      • getSymbolicValue

        public int getSymbolicValue()
        Description copied from class: TreeModel
        Get the integer constant used to identify this tree model in some legacy interfaces
        Overrides:
        getSymbolicValue in class TreeModel
        Returns:
        an integer constant used to identify the model, for example Builder.TINY_TREE
      • getName

        public java.lang.String getName()
        Description copied from class: TreeModel
        Get a name that identifies the tree model
        Overrides:
        getName in class TreeModel
        Returns:
        an identifying name for the tree model
      • getActiveSource

        public ActiveSource getActiveSource​(javax.xml.transform.Source supplied)
        Give this ExternalObjectModel the opportunity of recognising a Source object and returning an ActiveSource, which will be used to send an instance of this external model to a supplied Receiver. The default implementation returns null.
        Specified by:
        getActiveSource in interface ExternalObjectModel
        Parameters:
        supplied - a supplied Source
        Returns:
        an ActiveSource object if the source is recognised, or null if not
      • getDocumentBuilder

        public Receiver getDocumentBuilder​(javax.xml.transform.Result result)
                                    throws XPathException
        Test whether this object model recognizes a particular kind of JAXP Result object, and if it does, return a Receiver that builds an instance of this data model from a sequence of events. If the Result is not recognised, return null.

        This implementation always returns null (the Domino model is never used for transformation or query results)

        Specified by:
        getDocumentBuilder in interface ExternalObjectModel
        Parameters:
        result - a JAXP result object
        Returns:
        a Receiver that writes to that result, if available; or null otherwise
        Throws:
        XPathException - if any failure occurs
      • getPJConverter

        public PJConverter getPJConverter​(java.lang.Class<?> targetClass)
        Get a converter from XPath values to values in the external object model
        Specified by:
        getPJConverter in interface ExternalObjectModel
        Parameters:
        targetClass - the required class of the result of the conversion. If this class represents a node or list of nodes in the external object model, the method should return a converter that takes a native node or sequence of nodes as input and returns a node or sequence of nodes in the external object model representation. Otherwise, it should return null.
        Returns:
        a converter, if the targetClass is recognized as belonging to this object model; otherwise null
      • getJPConverter

        public JPConverter getJPConverter​(java.lang.Class sourceClass,
                                          Configuration config)
        Get a converter from values in the external object model to XPath values.
        Specified by:
        getJPConverter in interface ExternalObjectModel
        Parameters:
        sourceClass - the class (static or dynamic) of values to be converted
        config - the Saxon Configuration
        Returns:
        a converter, if the sourceClass is recognized as belonging to this object model; otherwise null
      • getNodeListCreator

        public PJConverter getNodeListCreator​(java.lang.Object node)
        Get a converter that converts a sequence of XPath nodes to this model's representation of a node list.

        This method is primarily for the benefit of DOM, which uses its own NodeList class to represent collections of nodes. Most other object models use standard Java collection objects such as java.util.List

        Specified by:
        getNodeListCreator in interface ExternalObjectModel
        Parameters:
        node - an example of the kind of node used in this model
        Returns:
        if the model does not recognize this node as one of its own, return null. Otherwise return a PJConverter that takes a list of XPath nodes (represented as NodeInfo objects) and returns a collection of nodes in this object model
      • unravel

        public NodeInfo unravel​(javax.xml.transform.Source source,
                                Configuration config)
        Wrap or unwrap a node using this object model to return the corresponding Saxon node. If the supplied source does not belong to this object model, return null
        Specified by:
        unravel in interface ExternalObjectModel
        Parameters:
        source - a JAXP Source object
        config - the Saxon configuration
        Returns:
        a NodeInfo corresponding to the Source, if this can be constructed; otherwise null
