ContextLinkBase Class

The base class for ContextLink. Represents a relationship between two ContextNodeBase objects that is not a parent-child relationship.

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

public class ContextLinkBase

Examples of the relationship represented by a ContextLinkBase object include:

To determine the relationship between SourceNode and DestinationNode get the SemanticType by calling the GetPropertyData method.

The following example finds all the nodes that are linked to the ContextNodeBase node, selectedNode. If selectedNode is not a destination node, the destination node is added to an ArrayList named destinationNodes. If selectedNode is not the source node, it is added to an ArrayList named 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 named theInkAnalyzerWithHint. It puts those nodes that are linked to a PropertyGuidsForAnalysisHintsBase with a Factoid value of "IS_DATE_FULLDATE" into a ContextNodeCollection named writingRegionsWithFactoids.

ContextNodeBaseCollection writingRegionsWithFactoids = 
    new ContextNodeBaseCollection(this.theInkAnalyzerBaseWithHint);
ContextNodeBaseCollection allWritingRegions =
    this.theInkAnalyzerBaseWithHint.FindNodesOfType(
        System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.WritingRegion);
foreach (ContextNodeBase writingRegion in allWritingRegions)
{
    // See if they are linked to any factoid 
    foreach (ContextLinkBase link in writingRegion.Links)
    {
        if (link.SourceNode.Type == ContextNodeTypeBase.AnalysisHint &&
            link.SourceNode.ContainsPropertyData(PropertyGuidsForAnalysisHintsBase.Factoid))
        {
            if ((string) link.SourceNode.GetPropertyData(PropertyGuidsForAnalysisHintsBase.Factoid)
                == "IS_DATE_FULLDATE")
            {
                writingRegionsWithFactoids.Add(writingRegion);
            }
        }
    }
}
