除了elementModel外，还有两个父类。

1.与label的显示有关的类吧。

public interface IShowHideLabel {
    public void setLabelShow(Object sel, boolean show);
    public boolean isLabelShow(Object sel);
    public boolean hasShowHideLabel(Object sel);
}

2.与连接有关的类

public interface IConnectMessage {
    public boolean canConnect(PortInstanceModel port);
    public void connectToPort(PortInstanceModel port);   不需要定义connectFromPort么？
    public PortInstanceModel getPort();
    public boolean isResizableMessage();  做什么的？
}

3.connectionElementModel

public abstract class ConnectionElementModel extends ElementModel 
        implements IShowHideLabel,IConnectMessage{
public ConnectionElementModel(String label, String modelID, Dimension size) {
        super(label, modelID,size);
        // TODO Auto-generated constructor stub    
        directionShow = false;
        valueShow = false;
        senderShow = false;
        paramShow = false;
        typeOrProcShow = false;
        templateShow =false;
    }
