Lifeline
A lifeline (structural) is a visual synonym of a lifeline. It adds no additional semantics; it is simply an alternative presentation of the lifeline element adapted for use on a communication diagram. In this form of the lifeline the instance is represented by the shape of the classifier, which may be a class, component, actor, use case or any other classifier. The lifeline does not have a dashed line like a sequence diagram, as time is not represented by any axis on a communication diagram. There is no standard form of this element as it has different presentations in the three different types of interaction diagrams and has two different presentations on a timing diagram.
