      • getName

        public java.lang.String getName()
        Description copied from class: TreeModel
        Get a name that identifies the tree model
        Overrides:

      • getPJConverter

        public PJConverter getPJConverter​(java.lang.Class<?> targetClass)
        Description copied from interface: ExternalObjectModel
        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)
        Description copied from interface: ExternalObjectModel
        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 object
        Returns:
        a converter, if the sourceClass is recognized as belonging to this object model; otherwise null

      • getNodeListCreator

        public PJConverter getNodeListCreator​(java.lang.Object node)

        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
