注意：是继承自AbstractModel（功能：监听）

public class DiagramModel extends AbstractModel {

public DiagramModel() {
        super();        
        name="";        
        initModel();  见下面：
    }

public void initModel(){
        setName("Diagram");        
        setDiagramDoc(DocumentHelper.createDocument());        创建document
        setRootElement(getDiagramDoc().addElement(ModelType.ELE_ROOT));
        setDiagramElement(getRootElement().addElement(ModelType.ELE_DIAGRAM));    
        setDiagramExElement(getRootElement().addElement(ModelType.ELE_DIAGRAMEX));
    }
添加根元素root，并且添加root的子元素diagram和diagramex。？？

public void doSaveXML() {
        // TODO Auto-generated method stub        
        this.addDiagramAttribute(ModelType.ATR_NAME, name); 先添加属性NAME和属性值name。

        getDiagramHead().doSaveXML();
        getComponent().doSaveXML();        
        
        for(int i=0;i<getPorts().size();i++){
            ((ElementModel)getPorts().get(i)).doSaveXML();
        }
        
        for(int i=0;i<getTexts().size();i++){
            ((ElementModel)getTexts().get(i)).doSaveXML();
        }
    }

protected void addDiagramAttribute(String name,String value){
        if(getDiagramElement()==null){
            return;
        }
        getDiagramElement().addAttribute(name, value);
    }
    
    protected void removeDiagramAttribute(String name){
        if(getDiagramElement()==null){
            return;
        }
        Attribute atr = getDiagramElement().attribute(name);
        if(atr != null){
            getDiagramElement().remove(atr);
        }
    }

public abstract class PortElementModel extends ElementModel {

定义一些属性：
private static final 
    IPropertyDescriptor[] descriptorPort = new IPropertyDescriptor[]{
        new PropertyDescriptor(SELECT_LABEL,"Model Label"),        
        new TextPropertyDescriptor(SELECT_NAME,"Port Name"),
        new TextPropertyDescriptor(SELECT_TYPE,"Port Type"),
    };

初始化：
public PortElementModel(String label, String modelID, Dimension size) {
        super(label, modelID, size);
        // TODO Auto-generated constructor stub
        name="";
        type="";
    }

保存：
public void doSaveXML() {
        // TODO Auto-generated method stub
        super.doSaveXML();  
        this.addXMLElementAttribute(ModelType.ELE_NAME, name);
        this.addXMLElementAttribute(ModelType.ELE_TYPE, type);
    }

public abstract class LiteralElementModel extends ElementModel {
public void doSaveXML() {
        // TODO Auto-generated method stub
        super.doSaveXML();
    }
}

    private List<Object> children = new ArrayList<Object>();
    private List<Object> ports = new ArrayList<Object>();      doSaveXML()

    private List<Object> containers = new ArrayList<Object>();
    private List<Object> portOps = new ArrayList<Object>();
    private List<Object> refers = new ArrayList<Object>();
        
    private ComponentInstanceModel component;    doSaveXML()

public ComponentInstanceModel getComponent() {
        return component;
    }
public void setComponent(ComponentInstanceModel component) {
        this.component = component;
    }

public void setDiagramHead(DiagramHeadingModel diagramHead) {
        this.diagramHead = diagramHead;
    }

        return diagramHead;
    }

 private String name; 

public String getName() {
        return name;
    }
public void setName(String name) {
        this.name = name;
    }

public void setDiagramDoc(Document diagramDoc) {
        this.diagramDoc = diagramDoc;
    }

        return diagramDoc;
    }

 private Element rootElement,diagramElement,diagramExElement;

public void setDiagramElement(Element diagramElement) {
        this.diagramElement = diagramElement;
    }
public Element getDiagramElement() {
        return diagramElement;
    }

public void setDiagramExElement(Element diagramExElement) {
        this.diagramExElement = diagramExElement;
    }
public Element getDiagramExElement() {
        return diagramExElement;
    }

        this.rootElement = rootElement;
    }
public Element getRootElement() {
