InkAnalyzer.RootNode 屬性
取得 InkAnalyzer 的根 ContextNode。
命名空間: Microsoft.Ink
組件: Microsoft.Ink.Analysis (在 Microsoft.Ink.Analysis.dll 中)
語法
'宣告
Public ReadOnly Property RootNode As ContextNode
'用途
Dim instance As InkAnalyzer
Dim value As ContextNode
value = instance.RootNode
public ContextNode RootNode { get; }
public:
property ContextNode^ RootNode {
ContextNode^ get ();
}
/** @property */
public ContextNode get_RootNode()
public function get RootNode () : ContextNode
屬性值
型別:Microsoft.Ink.ContextNode
InkAnalyzer 的根 ContextNode。
備註
InkAnalyzer 會維護 ContextNode 物件的樹狀目錄。這些物件同時包含分析的輸入內容和分析結果。筆劃一開始加入至 InkAnalyzer 時,InkAnalyzer 會將這些筆劃指派至 UnclassifiedInkNode。筆劃經過分析後,InkAnalyzer 就會將它們指派給樹狀目錄中適當的 ContextNode 物件。
範例
這個範例會呼叫 Helper 方法 CheckTreeNodes,檢查目前由 InkAnalyzer (theInkAnalyzer) 維護的所有 ContextNode 物件。
' Use a helper function to check all the ContextNode objects in
' the analyzer's tree.
CheckTreeNodes(Me.theInkAnalyzer.RootNode)
// Use a helper function to check all the ContextNode objects in
// the analyzer's tree.
CheckTreeNodes(this.theInkAnalyzer.RootNode);
在這個範例中,CheckTreeNodes 會接著將所遇到每個節點的相關資訊傳送至偵錯輸出。Helper 方法 GetContextNodeTypeName 不會顯示。

''' Checks the specified ContextNode and all of its descendents.

''' <param name="theContextNode">The node at which to start.</param>
