Why Aren’t There Any Operations to Choose from in Reverse Engineering of Sequence Diagram?

What you need to do to reverse engineer UML sequence diagram from Java code is to select the source folder first, and then pick-up an operation from the identified classes. Visual Paradigm will form a sequence diagram by analyzing the operation you selected. A frequently asked question about this process is “Why aren’t there any operations?” We are going to answer you why in this article.

How to Model Gates in UML Sequence Diagrams

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).

Using Alternative Combined Fragments in Sequence Diagram

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.
