<divid=Content><divclass="CClass"><divclass=CTopicid=MainTopic><h1class=CTitle><aname="mxGraphModel"></a>mxGraphModel</h1><divclass=CBody><p>Extends <ahref="../util/mxEventSource-js.html#mxEventSource"class=LClassid=link196onMouseOver="ShowTip(event, 'tt1', 'link196')"onMouseOut="HideTip('tt1')">mxEventSource</a> to implement a graph model. The graph model acts as a wrapper around the cells which are in charge of storing the actual graph datastructure. The model acts as a transactional wrapper with event notification for all changes, whereas the cells contain the atomic operations for updating the actual datastructure.</p><h4class=CHeading>Layers</h4><p>The cell hierarchy in the model must have a top-level root cell which contains the layers (typically one default layer), which in turn contain the top-level cells of the layers. This means each cell is contained in a layer. If no layers are required, then all new cells should be added to the default layer.</p><p>Layers are useful for hiding and showing groups of cells, or for placing groups of cells on top of other cells in the display. To identify a layer, the <ahref="#mxGraphModel.isLayer"class=LFunctionid=link197onMouseOver="ShowTip(event, 'tt31', 'link197')"onMouseOut="HideTip('tt31')">isLayer</a> function is used. It returns true if the parent of the given cell is the root of the model.</p><h4class=CHeading>Events</h4><p>See events section for more details. There is a new set of events for tracking transactional changes as they happen. The events are called startEdit for the initial beginUpdate, executed for each executed change and endEdit for the terminal endUpdate. The executed event contains a property called change which represents the change after execution.</p><h4class=CHeading>Encoding the model</h4><h4class=CHeading>To encode a graph model, use the following code</h4><blockquote><preclass="prettyprint">var enc = new mxCodec();
var node = enc.encode(graph.getModel());</pre></blockquote><p>This will create an XML node that contains all the model information.</p><h4class=CHeading>Encoding and decoding changes</h4><p>For the encoding of changes, a graph model listener is required that encodes each change from the given array of changes.</p><blockquote><preclass="prettyprint">model.addListener(mxEvent.CHANGE, function(sender, evt)
{
var changes = evt.getProperty('edit').changes;
var nodes = [];
var codec = new mxCodec();
for (var i = 0; i < changes.length; i++)
{
nodes.push(codec.encode(changes[i]));
}
// do something with the nodes
});</pre></blockquote><p>For the decoding and execution of changes, the codec needs a lookup function that allows it to resolve cell IDs as follows:</p><blockquote><preclass="prettyprint">var codec = new mxCodec();
codec.lookup = function(id)
{
return model.getCell(id);
}</pre></blockquote><p>For each encoded change (represented by a node), the following code can be used to carry out the decoding and create a change object.</p><blockquote><preclass="prettyprint">var changes = [];
var change = codec.decode(node);
change.model = model;
change.execute();
changes.push(change);</pre></blockquote><p>The changes can then be dispatched using the model as follows.</p><blockquote><preclass="prettyprint">var edit = new mxUndoableEdit(model, false);
'edit', edit, 'changes', changes));</pre></blockquote><!--START_ND_SUMMARY--><divclass=Summary><divclass=STitle>Summary</div><divclass=SBorder><tableborder=0cellspacing=0cellpadding=0class=STable><trclass="SMain"><tdclass=SEntry><ahref="#mxGraphModel">mxGraphModel</a></td><tdclass=SDescription>Extends <ahref="../util/mxEventSource-js.html#mxEventSource"class=LClassid=link1onMouseOver="ShowTip(event, 'tt1', 'link1')"onMouseOut="HideTip('tt1')">mxEventSource</a> to implement a graph model. </td></tr><trclass="SGroup SIndent1"><tdclass=SEntry><ahref="#mxGraphModel.Events">Events</a></td><tdclass=SDescription></td></tr><trclass="SEvent SIndent2 SMarked"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.CHANGE">mxEvent.<wbr>CHANGE</a></td><tdclass=SDescription>Fires when an undoable edit is dispatched. </td></tr><trclass="SEvent SIndent2"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.NOTIFY">mxEvent.<wbr>NOTIFY</a></td><tdclass=SDescription>Same as <ahref="#mxGraphModel.mxEvent.CHANGE"class=LEventid=link2onMouseOver="ShowTip(event, 'tt2', 'link2')"onMouseOut="HideTip('tt2')">mxEvent.CHANGE</a>, this event can be used for classes that need to implement a sync mechanism between this model and, say, a remote model. </td></tr><trclass="SEvent SIndent2 SMarked"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.EXECUTE">mxEvent.<wbr>EXECUTE</a></td><tdclass=SDescription>Fires between begin- and endUpdate and after an atomic change was executed in the model. </td></tr><trclass="SEvent SIndent2"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.EXECUTED">mxEvent.<wbr>EXECUTED</a></td><tdclass=SDescription>Fires between START_EDIT and END_EDIT after an atomic change was executed. </td></tr><trclass="SEvent SIndent2 SMarked"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.BEGIN_UPDATE">mxEvent.<wbr>BEGIN_UPDATE</a></td><tdclass=SDescription>Fires after the <ahref="#mxGraphModel.updateLevel"class=LVariableid=link3onMouseOver="ShowTip(event, 'tt3', 'link3')"onMouseOut="HideTip('tt3')">updateLevel</a> was incremented in <ahref="#mxGraphModel.beginUpdate"class=LFunctionid=link4onMouseOver="ShowTip(event, 'tt4', 'link4')"onMouseOut="HideTip('tt4')">beginUpdate</a>. </td></tr><trclass="SEvent SIndent2"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.START_EDIT">mxEvent.<wbr>START_EDIT</a></td><tdclass=SDescription>Fires after the <ahref="#mxGraphModel.updateLevel"class=LVariableid=link5onMouseOver="ShowTip(event, 'tt3', 'link5')"onMouseOut="HideTip('tt3')">updateLevel</a> was changed from 0 to 1. </td></tr><trclass="SEvent SIndent2 SMarked"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.END_UPDATE">mxEvent.<wbr>END_UPDATE</a></td><tdclass=SDescription>Fires after the <ahref="#mxGraphModel.updateLevel"class=LVariableid=link6onMouseOver="ShowTip(event, 'tt3', 'link6')"onMouseOut="HideTip('tt3')">updateLevel</a> was decreased in <ahref="#mxGraphModel.endUpdate"class=LFunctionid=link7onMouseOver="ShowTip(event, 'tt5', 'link7')"onMouseOut="HideTip('tt5')">endUpdate</a> but before any notification or change dispatching. </td></tr><trclass="SEvent SIndent2"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.END_EDIT">mxEvent.<wbr>END_EDIT</a></td><tdclass=SDescription>Fires after the <ahref="#mxGraphModel.updateLevel"class=LVariableid=link8onMouseOver="ShowTip(event, 'tt3', 'link8')"onMouseOut="HideTip('tt3')">updateLevel</a> was changed from 1 to 0. </td></tr><trclass="SEvent SIndent2 SMarked"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.BEFORE_UNDO">mxEvent.<wbr>BEFORE_UNDO</a></td><tdclass=SDescription>Fires before the change is dispatched after the update level has reached 0 in <ahref="#mxGraphModel.endUpdate"class=LFunctionid=link9onMouseOver="ShowTip(event, 'tt5', 'link9')"onMouseOut="HideTip('tt5')">endUpdate</a>. </td></tr><trclass="SEvent SIndent2"><tdclass=SEntry><ahref="#mxGraphModel.mxEvent.UNDO">mxEvent.UNDO</a></td><tdclass=SDescription>Fires after the change was dispatched in <ahref="#mxGraphModel.endUpdate"class=LFunctionid=link10onM
