5. Render graph.
-** example 1
+** example 1: individually picked objects
This example demonstrates generating of class graph from hand picked
-classes.
+classes and visualizing GraphViz itself.
#+BEGIN_SRC java
- // Create graph
- final ClassGraph graph = new ClassGraph();
- // While classes and objects can be immediately passed to ClassGraph
- // constructor as arguments, it is also possible to add them one by
- // one as in the following example.
+// Create graph
+final ClassGraph graph = new ClassGraph();
- // Add some object to the graph.
- graph.addObject(graph);
+// Add some random object to the graph. GraphViz will detect Class from
+// the object.
+graph.add(graph);
- // Add some class to the graph.
- graph.addClass(Utils.class);
+// Also add some random class to the graph.
+graph.add(Utils.class);
+
+// Keep intermediary GraphViz DOT file for reference.
+graph.setKeepDotFile(true);
+
+// Produce bitmap image titled "JavaInspect.png" to the user Desktop
+// directory
+graph.generateGraph("JavaInspect");
- // Produce bitmap image titled "JavaInspect.png" to the user Desktop
- // directory and keep intermediary GraphViz DOT file for reference.
- graph.generateGraph("JavaInspect", true);
#+END_SRC
+Note: if desired, more compact version of the above:
+#+BEGIN_SRC java
+new ClassGraph().add(randomObject, RandomClass.class)
+ .setKeepDotFile(true).generateGraph("JavaInspect");
+#+END_SRC
Result:
- Generated DOT file: [[file:JavaInspect.dot][JavaInspect.dot]]
- Generated PNG image: [[file:JavaInspect.png][JavaInspect.png]]
-** example 2
-Recursively scan current directory for Java source code and attempt to
-detect class names from there to be added to the graph.
-
+** example 2: scan java code, apply filters
#+BEGIN_SRC java
- graph.addProject(".");
+// Create graph
+final ClassGraph graph = new ClassGraph();
- // Blacklist example classes from being shown on the graph
- graph.getFilter().blacklistClassPattern(
- "eu.svjatoslav.inspector.java.structure.example.*");
+// Recursively scan current directory for Java source code and attempt
+// to detect class names from there to be added to the graph.
+graph.addProject(".");
- // do not show single classes with no relationships on the graph
- graph.hideOrphanedClasses();
+// Blacklist example classes from being shown on the graph
+graph.blacklistClassPattern("eu.svjatoslav.inspector.java.structure.example.*");
- // Produce bitmap image titled "JavaInspect full project.png" to the
- // user Desktop directory.
- graph.generateGraph("JavaInspect full project");
+// do not show single classes with no relationships on the graph
+graph.hideOrphanedClasses();
+
+// Produce bitmap image titled "JavaInspect full project.png" to the
+// user Desktop directory.
+graph.generateGraph("JavaInspect full project");
#+END_SRC
Result:
- Generated PNG image: [[file:JavaInspect%20full%20project.png][JavaInspect full project.png]]
+** example 3: GraphViz embedded in another project
+1. Download project Sixth [[http://www2.svjatoslav.eu/gitweb/?p=sixth.git;a=snapshot;h=HEAD;sf=tgz][code snapshot]].
+2. Inspect and run *DataGraph.java*.

* Embedding JavaInspect in your Maven project
Declare JavaInspect as dependency:
#+BEGIN_SRC xml
- <dependencies>
- ...
- <dependency>
- <groupId>eu.svjatoslav</groupId>
-
<artifactId>javainspect</artifactId>
- <version>1.3</version>
- </dependency>
- ...
- </dependencies>
+<dependencies>
+ ...
+ <dependency>
+ <groupId>eu.svjatoslav</groupId>
+ <artifactId>javainspect</artifactId>
+ <version>1.5-SNAPSHOT</version>
+ </dependency>
+ ...
+</dependencies>
#+END_SRC
Add Maven repository to retrieve artifact from:
#+BEGIN_SRC xml

#+END_SRC
* Requirements
-
[[http://www.graphviz.org/][GraphViz]] - shall be installed on the computer.
On Ubuntu/Debian use:
-: sudo apt-get install graphviz
-* TODO
+#+BEGIN_SRC sh
+sudo apt-get install graphviz
+#+END_SRC
+* TO DO
- BUG: Should not hide references if there are too many of them to
classes if referring classes are not visible anyway because of
blacklist/whitelist rules. Basically reference counting should
exclude not visible classes.
-- BUG: Current code is quite messy (because of lack of time) things
- were implemented ad-hoc. Needs cleanup/refactoring for better
- readability.
- FEATURE: add dark theme
- FEATURE: sort Class fields by alphabet
- FEATURE: visualize also concrete field values so it could be used as
projects / javainspect.git / blobdiff
