In the TestStand API, many objects reference other types of objects. You can obtain an object of one class from an object of another class by calling a method or accessing a property. For example, you can obtain the Engine, Thread, Execution, and Report objects from the SequenceContext object. In another example, a UIMessage object references an Execution object, and an Execution object references a SequenceFile object.
