1.DiagramModel

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。？？

1.1 doSaveXML()

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

1.1.1 addDiagramAttribute(ModelType.ATR_NAME, name);

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);        }    }

1.1.2 getDiagramHead().doSaveXML();

public DiagramHeadingModel getDiagramHead() {		return diagramHead;	}

public class DiagramHeadingModel extends ElementModel {

先定义一些属性，并且定义一个结构体        private String definition,myCtype,myReturn,mySystem,diagramType;	private boolean isRetShow,isSysShow,isRunsOnShow;	public static final String SELECT_DEF = "select_def";	public static final String SELECT_CTYPE = "select_ctype";	public static final String SELECT_RETURN = "select_return";	public static final String SELECT_SYSTEM = "select_system";	public static final String SELECT_DIAGRAM = "select_diagram";		private IPropertyDescriptor[] descriptor; 	private List
     
       descriptorList = new ArrayList
      
       ();	private static final 	TextPropertyDescriptor definitionDescriptor = new TextPropertyDescriptor(SELECT_DEF,"Definition");	private static final 	TextPropertyDescriptor ctypeDescriptor = new TextPropertyDescriptor(SELECT_CTYPE,"runs On");	private static final 	TextPropertyDescriptor returnDescriptor = new TextPropertyDescriptor(SELECT_RETURN,"return");	private static final 	TextPropertyDescriptor systemDescriptor = new TextPropertyDescriptor(SELECT_SYSTEM,"system");	private static final 	PropertyDescriptor diagramDescriptor = new PropertyDescriptor(SELECT_DIAGRAM,"Diagram Type");		public DiagramHeadingModel() {		super(ConstantResourceFactory.LABEL_DIAGRAMHEAD_MODEL,				ConstantResourceFactory.ID_DIAGRAMHEAD_MODEL,				ConstantResourceFactory.SIZE_DIAGRAMHEAD);		// TODO Auto-generated constructor stub		definition="";		myCtype="";		myReturn="";		mySystem="";		diagramType="";		isRetShow=false;		isSysShow=false;		isRunsOnShow=false;	}

public IPropertyDescriptor[] getPropertyDescriptors() {		// TODO Auto-generated method stub		if(descriptor == null){			descriptorList.add(definitionDescriptor);			descriptorList.add(diagramDescriptor);			if(isRunsOnShow()){				descriptorList.add(ctypeDescriptor);			}			if(isRetShow()){				descriptorList.add(returnDescriptor);			}			if(isSysShow()){				descriptorList.add(systemDescriptor);			}			descriptor = (IPropertyDescriptor[]) descriptorList							.toArray(new IPropertyDescriptor[1]);		}							return descriptor;	}

然后保存，过程就是两步：首先继承elementModel的dosaveXML，然后添加自己的属性。public void doSaveXML() {		// TODO Auto-generated method stub		super.doSaveXML();				this.addXMLElementAttribute(ModelType.ATR_DIAGRAM,diagramType);		this.addXMLElementAttribute(ModelType.ATR_DEFINITION,definition);		if(isRunsOnShow()){			this.addXMLElementAttribute(ModelType.ATR_RUNSON,myCtype);		}		else{			this.removeXMLElementAttribute(ModelType.ATR_RUNSON);		}				if(isRetShow()){			this.addXMLElementAttribute(ModelType.ATR_RETURN,myReturn);		}		else{			this.removeXMLElementAttribute(ModelType.ATR_RETURN);		}				if(isSysShow()){			this.addXMLElementAttribute(ModelType.ATR_SYSTEM,mySystem);		}		else{			this.removeXMLElementAttribute(ModelType.ATR_SYSTEM);		}	}

1.1.3 getComponent().doSaveXML();

public ComponentInstanceModel getComponent() {		return component;	}

public void doSaveXML() {		// TODO Auto-generated method stub		super.doSaveXML();						for(int i=0;i

1.1.4 ((ElementModel)getPorts().get(i)).doSaveXML();

到了最重要的portelementmodel了。

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);    }

1.1.5 ((ElementModel)getTexts().get(i)).doSaveXML();

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

1.2 DiagramModel中定义的变量

private List

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

private DiagramHeadingModel diagramHead;     doSaveXML()

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

private String name;

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

private Document diagramDoc;

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

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