This is a proof of concept for making a graphviz -file based on flow of java code. The main idea is to build a (graphviz) DOT -file. Aspects (Around aspects) "dives" into the code-flow and builds a graph-file according to the pointcuts. It also serializes parameter and result values as xml-files and has references to the files on the arrows. Also has a Servlet which lists the graphviz -files (found in java.io.tempdir). Converts to svg and outputs if a graphviz -file is clicked. See sample graphviz file in doc/sample (may be out-dated, as I may forget to keep this doc updated) ## Use the tests in src/test/java and src/test/resources for sample ## The java code mimics a semi-complex multi-layered -structure, which has the following top-down layers: - Action (imagine this to be the entry point for some GUI) - Adapter (imagine this to be where we translate DTO) - Facade (Inside of some service we've created) - Service and Repository. (Stuff we're doing inside the facade) Only the Graphviz -domain model has unit tests. The Aspect, (threadlocal) Context and Servlet doesn't have unit tests. environment variable MAKE_GRAPHS must be TRUE, or nor the graph file or parameter/result -xml files will be written. - Set environment variable MAKE_GRAPHS to TRUE - Run ActionIntegrationTest (which will save a graph or two to /tmp/) - rin #mvn jetty:run - browse to http://localhost:8080/vizpoc/graph - the rest you'll understand from the web -page.
