Interaction reference attached lifelines consistency

Chapter 9 Working with Object-Oriented Models

Interaction reference attached lifelines consistency

The interaction reference symbol has a list of attached lifelines, which correspond to actors and objects. These actors and objects must match a subset of the ones displayed in the referenced sequence diagram. This corresponds to a subset because some lifelines in referenced diagram could not be displayed in the diagram of the interaction reference. The current check verifies the following consistency rules:

The number of attached lifelines cannot be greater than the number of lifelines in the referenced diagram
If one attached lifeline corresponds to an object, and if this object has an associated metaclass, then there must be at least one object in the referenced sequence diagram that is associated to the same metaclass

Manual correction	Automatic correction
Change the list of attached lifelines for the interaction reference object. This can be done simply by resizing the interaction reference symbol or by clicking with the pointer tool on the intersection of the interaction reference symbol and the lifeline. The tool cursor changes on this area and allows you to detach the interaction reference symbol from (or attach it to) the lifeline.	None
