Valore proprietà
Tipo: System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
Oggetti ContextNodeBase associati a questa alternativa.
Note
Poiché corrispondono ad alternative, questi oggetti ContextNodeBase non sono discendenti di RootNode di InkAnalyzerBase, a meno che non siano la prima alternativa, ovvero il primo elemento in AnalysisAlternateBaseCollection.
Esempi
Nell'esempio seguente viene determinato se un oggetto AnalysisAlternateBase, selectedAlternate, presenta la stessa segmentazione della prima alternativa in AnalysisAlternateBaseCollection, currentAlternates. Per segmentazione si intende il modo in cui i tratti vengono separati in oggetti ContextNodeBase.
Dim hasSameSegmentationAsTop As Boolean = True
If currentAlternates.Count > 0 Then
Dim topAlternate As AnalysisAlternateBase = currentAlternates(0)
' First check if selected alternate is the top alternate
If selectedAlternate.Equals(topAlternate) Then
hasSameSegmentationAsTop = True
Else
' Check to see if they have the same strokes
If topAlternate.AlternateNodes.Count <> selectedAlternate.AlternateNodes.Count Then
hasSameSegmentationAsTop = False
Else
' Check that each node matches the alternates
For index As Integer = 0 To topAlternate.AlternateNodes.Count - 1
Dim selectedAlternateNodesStrokes As Strokes = _
theInk.CreateStrokes(selectedAlternate.AlternateNodes(index).GetStrokeIds())
Dim topAlternateNodesStrokes As Strokes = _
theInk.CreateStrokes(topAlternate.AlternateNodes(index).GetStrokeIds())
For Each topStroke As Stroke In topAlternateNodesStrokes
If (Not selectedAlternateNodesStrokes.Contains(topStroke)) Then
hasSameSegmentationAsTop = False
Exit For
End If
Next topStroke
Next index
End If
End If
End If
bool hasSameSegmentationAsTop = true;
if (currentAlternates.Count > 0)
{
AnalysisAlternateBase topAlternate = currentAlternates[0];
// First check if selected alternate is the top alternate
if (selectedAlternate == topAlternate)
{
hasSameSegmentationAsTop = true;
}
else
{
// Check to see if they have the same strokes
if (topAlternate.AlternateNodes.Count != selectedAlternate.AlternateNodes.Count)
{
hasSameSegmentationAsTop = false;
}
else
{
// Check that each node matches the alternates
for (int i = 0; i < topAlternate.AlternateNodes.Count; i++)
{
Strokes selectedAlternateNodesStrokes =
theInk.CreateStrokes(selectedAlternate.AlternateNodes[i].GetStrokeIds());
Strokes topAlternateNodesStrokes =
theInk.CreateStrokes(topAlternate.AlternateNodes[i].GetStrokeIds());
foreach (Stroke stroke in topAlternateNodesStrokes)
