List of disconnectChildNodesFromClient() Examples

Examples of disconnectChildNodesFromClient()

org.itsnat.core.ItsNatDocument.disconnectChildNodesFromClient()

Removes the child nodes of the specified node to save server memory but not in client.

After this call the child nodes in client are not longer in sync with server and can be freely manipulated (including insertion and removing).

The specified node is marked as "child nodes disconnected", the inmmediate call to {@link #isDisconnectedChildNodesFromClient(Node)} will return true.

Returns the removed child nodes following the same criteria as {@link org.itsnat.core.domutil.ItsNatDOMUtil#extractChildren(Node)}.

If the content of the parent node is already disconnected or is a node not into the document an {@link ItsNatException} is thrown.

@param node the parent node which content is going to be disconnected and removed. @return null if empty, the child node when only a child node or a DocumentFragment containing the child nodes. @see #reconnectChildNodesToClient(Node)

    {
        // Because is going to be removed (is not mandatory but recommended)
        ((EventTarget)disconnectChildNode).addEventListener("click",this,false);


        ItsNatDocument itsNatDoc = getItsNatDocument();
        this.childNodes = (DocumentFragment)itsNatDoc.disconnectChildNodesFromClient(container);
        if (container.hasChildNodes())
            throw new RuntimeException("Unexpected Error");


        setupToReconnectChildNodes();
    }

        container.appendChild(elemTemp);
        if (itsNatDoc.isDisconnectedChildNodesFromClient(container))
            throw new RuntimeException("Unexpected Error");


        // Disconnecting again (the container only has one child node)
        Element elemTemp2 = (Element)itsNatDoc.disconnectChildNodesFromClient(container);
        if (elemTemp != elemTemp2) throw new RuntimeException("Unexpected Error");


        // Finally explicit reconnection, previous content is restored, the client DOM
        // is again in sync with server removing current content in client
        itsNatDoc.reconnectChildNodesToClient(container);
