Write a similar aspect to log the execution of all public methods in the figures package. This time, include the string representation of the receiver as well as the join point. The log lines should follow this pattern: text/html 2021-02-05T12:55:48+00:00 Anonymous (anonymous@undisclosed.example.com) http://soft.vub.ac.be/ajtraining/tracing:ex3?rev=1612529748&do=diff Intro Ex1 Ex2 Ex3 Context: Points in groups Specialized tracing Task: Pass the suite tests.PointGroupLog. Write an aspect to log whenever a Point is added to a Group. Note that this requires a dynamic instanceof test, because in principle any figure element can be added to a group. The log message should simply be: text/html 2021-02-05T12:55:55+00:00 Anonymous (anonymous@undisclosed.example.com) http://soft.vub.ac.be/ajtraining/tracing:intro?rev=1612529755&do=diff Intro Ex1 Ex2 Ex3 Tracing: Intro Tracing and logging is the “Hello world” of aspect-oriented programming. In these exercises, we will develop some tracing behavior using aspects. Set-up & Running You can reuse the AspectJ project with the figure editor application you have created during the previous track. If you haven't got such a project yet, consult the
