Generate & display class hierarchy diagrams for Java classes.

Uses Graphviz via Rhizome to generate graphs.

This tool helps you examine subsets of a class hierarchy. To see all of Clojure's built-in classes and interfaces in one big diagram, try the Clojure class chart by Chouser.

Maven dependency information:


Git master branch is at version 0.1.1-SNAPSHOT

Usage and Examples

(require '[com.stuartsierra.class-diagram :as diagram])

To open up a window showing the class hierarchy diagram of Clojure's persistent list:

(diagram/view clojure.lang.PersistentList)

Or save it to a PNG file:

(diagram/png "PersistentList.png" clojure.lang.PersistentList)

Say you want to understand the relationships among Clojure's persistent map types:

(->> [(hash-map 1 2) (array-map) (sorted-map)]
     (map class)
     (apply diagram/view))

(You have to call hash-map with arguments because an empty map defaults to an array-map.)

Note: The diagrams only show ancestors of the input classes, not subclasses.

You can get a legend for the symbols and colors used in the diagram:


Or save that to a file:

(diagram/png-legend "legend.png")
