      • getDataModel

        public static DataModel getDataModel​(AppModel app,

        bCreateIfNotFound - when true, create a data model if needed.
        bAppend - when true, append any underling xml to the xfa root element when loading, and when false, create orphan xfa:datasets and xfa:data nodes. This behaviour occurs only works when bCreateIfNotFound is set to true.

        Parameters:
        e - the element to search
        aNodeName - the local name of the attribute
        Returns:
        attribute index. -1 if not found.

        Given an array of attributes, find the specified node name which exists in a namespace that is compatible with this data model's namespace. (This is a direct port of the C++ method by the same name, unlike the other variant of findAttrInNS above).
        Parameters:
        attrs - the array of attributes to search
        aNodeName - the local name of the attribute
        Returns:
        the attribute. null if not found.

      • connectPeerToDocument

        public void connectPeerToDocument()
        Description copied from class: Element
        connectPeerToDocument() is used to rearrange the DOM tree when inserting or appending a node. It is provided here as a utility function for derived classes that could be adding child nodes, when peered against an orphan node. In particular, this happens with xfa:datasets and xfa:data, both of which may be created during the load process. On the C++ side, this method is only used by the data model. Due to the differences between the relationship of Documents and AppModels in Java, on the Java side it is also called when creating a DOM from scratch, from any ModelFactory's createDOM method. In the DataModel context at least, it should only be called if the DOM peer is an orphan. It takes that orphan and connects it to the document, and then moves the original peer of this node to be a child of the node that previously was orphaned.
        Overrides:
        connectPeerToDocument in class Element
