Sequence fragments make it easier to create and maintain accurate sequence diagrams; A sequence fragment is represented as a box, called a combined fragment, which encloses a portion of the interactions within a sequence diagram; The fragment operator (in the top left corner) indicates the The Fragment displays as a transparent window, divided by horizontal lines for each operand. Loop Fragment: The Loop fragment is a dynamic way to represent repetitive actions in a sequence diagram. The loop condition is checked before each iteration, and the sequence of interactions within the loop is repeated as long as One important feature of sequence diagrams is the ability to represent loops, which allow for the modeling of repeated interactions between objects. neg: Negative: the fragment shows an invalid interaction. Indeed, the activity diagram is more appropriate to model control logic that involves conditions, loop etc, but in practice, most developers prefer to stick with the sequence diagram to show how objects interact together with the control logic involved. Loop to execute exactly 10 times. Its designer-crafted, professionally designed and helps you stand out. The fragment operator (in the upper left corner) indicates the type of the fragment. critical: Critical region: the fragment can have only one thread executing it at once. This sequence diagram example shows a loop fragment to be repeated until some guard condition becomes false. 0 introduces sequence (or interaction) fragments. Author Sequence Diagram Fragments.
