VirtualLinkData

public object From { get; private set; }

value = virtualLinkData.From
virtualLinkData.From = value

Gets the data object for the "from" end of this link relationship.

public object To { get; private set; }

value = virtualLinkData.To
virtualLinkData.To = value

Gets the data object for the "to" end of this link relationship.

public override bool Equals(object obj)

result = virtualLinkData.Equals(obj)

Two VirtualLinkData objects are effectively the same if the From and To data objects are equal.

obj

public override int GetHashCode()

result = virtualLinkData.GetHashCode()

This is just the combination of the hash codes for the From and To data objects.

public override string ToString()

result = virtualLinkData.ToString()

This is might be useful for debugging.

public event PropertyChangedEventHandler PropertyChanged

virtualLinkData.PropertyChanged += handler

This implementation of INotifyPropertyChanged does nothing.
