This can be used by the application to 286N/A * implement various behaviors regarding the data it associates to the DOM 286N/A * nodes. This interface defines that handler. 286N/A * The node is cloned, using <code>Node.cloneNode()</code>. 286N/A * The node is imported, using <code>Document.importNode()</code>. 286N/A * <p ><b>Note:</b> This may not be supported or may not be reliable in 286N/A * certain environments, such as Java, where the implementation has no 286N/A * real control over when objects are actually deleted. 286N/A * The node is renamed, using <code>Document.renameNode()</code>. 286N/A * The node is adopted, using <code>Document.adoptNode()</code>. 286N/A * This method is called whenever the node for which this handler is 286N/A * registered is imported or cloned. 286N/A * <br> DOM applications must not raise exceptions in a 286N/A * <code>UserDataHandler</code>. The effect of throwing exceptions from 286N/A * the handler is DOM implementation dependent. 286N/A * @param operation Specifies the type of operation that is being 286N/A * performed on the node. 286N/A * @param key Specifies the key for which this handler is being called. 286N/A * @param data Specifies the data for which this handler is being called. 286N/A * @param src Specifies the node being cloned, adopted, imported, or 286N/A * renamed. This is <code>null</code> when the node is being deleted. 286N/A * @param dst Specifies the node newly created if any, or
