Portal學習--核心類分析

簡述:  
Portal的核心功能就是Components文件夾中的類(Configuration組件,及AnnouncementsDB,ContactsDB,DocumentDB等...);它相當於多層結構中的Model層.  
其中Configuration組件又是這個核心的核心,它用於對網站的配置做操作.它分成三大部分.

1.Configuration類,它用於操作一個配置站點用的SiteConfiguration(繼承自DataSet)類型的SiteSetting,主要是對四個表(Global,Tabs,Modules,ModuleDefinitions)的操作以及對整個數據集資料的獲取,因為對它們的操作,其實都是對同一個xml文件的操作,所在放在同一個類中應該比較方便.

2.SiteSetting中有多個門戶PortalSettings,每個PortalSettings有由多個TabSettings組成,每個TabSettings又包含有多個ModuleSettings.所以定義了3個類(PortalSettings,TabSettings,ModuleSettings);它們是依次嵌套的.  
下面是它們的字段:

public  class  PortalSettings  
\{  
 public  int  PortalId;  // 門戶站點Id   
  public  String PortalName;  // 門戶站點名稱   
  public  bool  AlwaysShowEditButton;  // 是否顯示編輯按鈕   
  public  ArrayList DesktopTabs  =  new  ArrayList();  // 門戶站點“桌面瀏覽器”顯示部分的導航欄標簽的ArrayList   
  public  ArrayList MobileTabs  =  new  ArrayList();  
 public  TabSettings ActiveTab  =  new  TabSettings();  // 當前標簽  
  
 // ...public PortalSettings(int tabIndex, int tabId)    
 \}  
 public  class  TabSettings  
\{  
 public  int  TabIndex;  // 標簽索引   
  public  int  TabId;  // 標簽Id   
  public  String TabName;  // 標簽名稱   
  public  int  TabOrder;  // 標簽排序號   
  public  String MobileTabName;  // “移動設備瀏覽器”上顯示的標簽名稱   
  public  String AuthorizedRoles;  // 可訪問角色   
  public  bool  ShowMobile;  // 是否在“移動設備瀏覽器”上顯示   
  public  ArrayList Modules  =  new  ArrayList();  // 當前標簽下的模塊對像list   
 \}  
 public  class  ModuleSettings : IComparable  
\{  
 public  int  ModuleId;  // 模塊Id   
  public  int  ModuleDefId;  // 用於定義該模塊的原始模板ID   
  public  int  TabId;  // 隸屬標簽Id   
  public  int  CacheTime;  // 緩存時間   
  public  int  ModuleOrder;  // 模塊序號   
  public  String PaneName;  // 顯示在那個板塊中（左中右）   
  public  String ModuleTitle;  // 模塊標題   
  public  String AuthorizedEditRoles;  // 可編輯角色   
  public  bool  ShowMobile;  // 是否在移動瀏覽器上顯示   
  public  String DesktopSrc;  // 桌面源   
  public  String MobileSrc;  // 移動源  
 // ....public int CompareTo(object value)    
 \}

3.因為每次在頁面中只顯示一個TabSettings的內容,所以要有一個導航條,為管理導航條,又定了一個類TabStripDetails;  
同時為了可以配置每個TabSettings及ModuleSettings的順序,又定義了兩個類TabItem,ModuleItem,並且都實現了CompareTo接口;  
以上三個類都比較簡單,只保留了必要的屬性字段.

public  class  TabStripDetails  
\{  
 public  int  TabId;  // 標簽Id   
  public  String TabName;  // 標簽名稱   
  public  int  TabOrder;  // 標簽排序號   
  public  String AuthorizedRoles;  // 可訪問角色   
 \}  
  
 public  class  TabItem : IComparable  
\{  
 private  int  \_tabOrder;  
 private  String \_name;  
 private  int  \_id;  
 // ...屬性字段定義  
 // ...public int CompareTo(object value)    
 \}  
  
 public  class  ModuleItem : IComparable  
\{  
 private  int  \_moduleOrder;  // 模塊序號   
  private  String \_title;  // 模塊名稱   
  private  String \_pane;  // 放置模塊的面板名稱   
  private  int  \_id;  // 模塊ID   
  private  int  \_defId;  // 定義該模塊的模板ID  
 // ...屬性字段定義  
 // ...public int CompareTo(object value)    
 \}

附Configuration類的源代碼:
