PlantUML: Customize arrow style in a sequence diagram

Arrow style can be customized in various ways. Find the below examples.

 

1.   add a final x to denote a lost message

2.   use \ or / instead of < or > to have only the bottom or top part of the arrow

3.   repeat the arrow head (for example, >> or //) head to have a thin drawing

4.   use -- instead of - to have a dotted arrow

5.   add a final ”o” at arrow head

6.   use bidirectional arrow <->
