ContextLink Class

Represents a relationship between two ContextNode objects that is not a parent-child relationship.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)

public class ContextLink

Examples of the relationship represented by a ContextLink relationship include:

To determine the relationship between SourceNode and DestinationNode uses the InkDrawingNode.SemanticType or WritingRegionNode.SemanticType property on the appropriate node.

The following example finds all the nodes that are linked to ContextNode node, selectedNode. If selectedNode is not a destination node, the destination node is added to an ArrayList, destinationNodes. If selectedNode is not the source node, it is added to an ArrayList, sourceNodes.

ArrayList destinationNodes = new ArrayList();
ArrayList sourceNodes = new ArrayList();

// Find all the nodes that link to the currently selected node. 
foreach (Microsoft.Ink.ContextLink link in selectedNode.Links)
{
    if (link.DestinationNode != selectedNode)
    {
        destinationNodes.Add(link.DestinationNode);
    }

    if (link.SourceNode != selectedNode)
    {
        sourceNodes.Add(link.SourceNode);
    }

}

The following example finds all WritingRegionNode objects in the node tree of an InkAnalyzer, theInkAnalyzerWithHint. It then puts those that are linked to an AnalysisHintNode with a Factoid of "IS_DATE_FULLDATE" into a ContextNodeCollection, writingRegionsWithFactoids.

ContextNodeCollection writingRegionsWithFactoids = 
    new ContextNodeCollection(this.theInkAnalyzerWithHint);
ContextNodeCollection allWritingRegions =
    this.theInkAnalyzerWithHint.FindNodesOfType(Microsoft.Ink.ContextNodeType.WritingRegion);
foreach (WritingRegionNode writingRegion in allWritingRegions)
{
    // See if they are linked to any factoid 
    foreach (ContextLink link in writingRegion.Links)
    {
        if (link.SourceNode.Type == ContextNodeType.AnalysisHint)
        {
            AnalysisHintNode hint = (AnalysisHintNode) link.SourceNode;
            if (hint.Factoid == "IS_DATE_FULLDATE")
            {
                writingRegionsWithFactoids.Add(writingRegion);
            }
        }
    }
}
