To pass a message between two sequence diagrams in UML modeling, we can make use of gates. Through modeling gates, we could relate the message outside an interaction fragment with message inside another interaction fragment.
Graphically a gate, with an arrowed line, connects to the sequence diagram’s frame edge with one end and the other end connected to a lifeline.
In this tutorial we will show you how to model gates in sequence diagrams using Visual Paradigm for UML (VP-UML).
When reversing Java code to sequence diagram, sometimes you may not be able to specify a method for conversion. In the dialog box, somehow the class (to which the method belongs) can’t seem to be expanded to list anything and therefore the method is nowhere to be selected. What happens?
An alternative combined fragment is used to specify an area of a group of lifelines/ actors to show conditional flow in a sequence diagram. It also models the if-then-else logic in the sequence diagram. In this page, we will demonstrate how to draw a simple sequence diagram with applying alternative combined fragment.
Visual Paradigm supports collaborative and concurrent modeling, and versioning of works in the following ways:
In this page, we will have an overview on how administrator and team members can work together with Visual Paradigm’s team collaborative features, and to clarify some of the major concepts in collaborative modeling.
