FindLinksConnectedWithPort(string) : IEnumerable<Link>

Returns a collection of Links that are connected to a particular port in either direction.

FindPort(string, bool) : FrameworkElement

Find the FrameworkElement in this node whose Node.PortId attached property matches a given port parameter value.

If there is no such child element, it searches for an element whose DependencyObject) value is the empty string. Finally, when failing to find a port with either the given name or the empty string, this method returns the root visual element for the node.
