Remarks

Use this method to navigate from a ___domain model element or relationship to the shape or link that represents it in the user interface. Unless you have made a major customization to the DSL, there will be one presentation element for each ___domain element. In some cases while the display is being initialized, there might be no display element. There will be no display element if you have not set a Domain Element Mapping for the ___domain class in your DSL Definition.

For a specific class of ___domain element, the Domain Element Mapping specifies the class of the presentation element – a shape or link.

Examples

ExampleElement element = ...;
ExampleShape shape = PresentationViewsSubject.GetPresentation(element).FirstOrDefault() as ExampleShape;
if (shape != null) {...}

// A ___domain relationship:
ExampleElementReferencesTargets relationship = ...; 
// In the DSL Definition, this relationship is mapped to the following BinaryLinkShape:
ExampleConnector link = PresentationViewsSubject.GetPresentation(relationship).FirstOrDefault() as ExampleConnector;
if (link != null) {...}
