Article

Gets the root ContextNodeBase of the ink analyzer's context node tree.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Syntax

'Declaration
Public ReadOnly Property RootNode As ContextNodeBase
'Usage
Dim instance As InkAnalyzerBase 
Dim value As ContextNodeBase 

value = instance.RootNode

public ContextNodeBase RootNode { get; }

public:
property ContextNodeBase^ RootNode {
    ContextNodeBase^ get ();
}

public function get RootNode () : ContextNodeBase

Property Value

Type: System.Windows.Ink.AnalysisCore.ContextNodeBase
The root ContextNodeBase of the ink analyzer's context node tree.

Remarks

The InkAnalyzerBase maintains a tree of ContextNodeBase objects. These objects contain both input for analysis and the results of analysis. When strokes are initially added to the ink analyzer, the analyzer assigns them to a ContextNodeBase that has a Type property value of ContextNodeTypeBase.UnclassifiedInk. After the strokes are analyzed, the InkAnalyzerBase assigns them to appropriate ContextNodeBase objects in the tree.

Examples

This example iterates over the child nodes of the root node for an InkAnalyzerBase, theInkAnalyzerBase. If a child node is an unclassified ink node, the node is added to a collection.

' Iterate over the subnodes of the analyzer's root node and 
' collect all unclassified ink nodes. 
Dim theUnclassifiedInkNodes As New System.Collections.ArrayList()
Dim theNode As System.Windows.Ink.AnalysisCore.ContextNodeBase
For Each theNode In theInkAnalyzerBase.RootNode.SubNodes
    If System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.UnclassifiedInk = theNode.Type Then
        theUnclassifiedInkNodes.Add(theNode)
    End If 
Next theNode

// Iterate over the subnodes of the analyzer's root node and 
// collect all unclassified ink nodes.
System.Collections.ArrayList theUnclassifiedInkNodes =
    new System.Collections.ArrayList();
foreach (System.Windows.Ink.AnalysisCore.ContextNodeBase theNode
    in theInkAnalyzerBase.RootNode.SubNodes)
{
    if (System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.UnclassifiedInk == theNode.Type)
    {
        theUnclassifiedInkNodes.Add(theNode);
    }
}
