5.1.2 Specifying classes to render

+
+

+Normal Java application has immense complexity. In addition to code +that was directly written by particular project developers, lots of +functionality is typically added as frameworks or libraries to the +project. In addition there is significant Java standard library. +

+ +

+Because JavaInspect uses reflection, it does not easily distinguish +between those. In normal situation you would rather want to visualize +only code that was developed specifically for your project and leave +frameworks like Spring etc. out. If you visualize all classes that are +possibly reachable from you project, you will easily get huge and +incomprehensible graph. +

+ +

+JavaInspect can digest compiled Java classes in 2 modes: +

+
    +
  1. Provide list of Jar files. Use -j option.
  2. +
  3. Provide list of filesystem directories that can be used as +classpath root. Use -c option.
  4. +
+ +

+Currently JavaInspect uses following algorithm to add classes to +rendered graph: +

+ +
    +
  • All classes that were found in Jar files are added to graph by default.
  • +
  • None of the classes that were found in filesystem directories are +added to the graph by default (unless explicitly referenced). (TODO: +for consistency it would be better to add them too by default)
  • +
  • If whitelist is specified (-w option) everything that is not +matched by whitelist pattern(s) will be removed from the graph.
  • +
  • If blacklist is specified (-b option) everything that is matched +by blacklist pattern(s) will be removed from the graph.
  • +
  • Root classes can be specified using -r option. Root classes will +be added to the graph. JavaInspect will then try to recursively +discover all classes that were referenced by root class and add +those also to the graph.
  • +
+
+
+
+ +
+
