JGraLab is a Java graph library implementing so-called TGraphs: typed, attributed, ordered, and directed graphs. Beyond the plain data structure, the library contains an extensive algorithm library, the graph query language GReQL, the transformation API GReTL, and tons of utilities.
The following assumes that you create (or use) a workspace folder
jgsrc for JGraLab
and your JGraLab applications. Name and location of that workspace can be arbitrarily
When you plan to use Eclipse as IDE, the easiest is to put the
jgralab folder into
your Eclipse workspace folder.
The Ant build scripts require that your applications are located
in sibling folders next to
jgsrc/ # your jgralab workspace +-> jgralab/ # this project, i.e., jgralab itself +-> mygraphproject # your app has to sit next to jgralab
jgralab you need to have Apache Ant.
$ cd jgsrc/jgralab/ $ ant
jgralab folder contains an Eclipse
.classpath file, so that you
can import it in Eclipse as existing project. This import step is necessary also when
you initially decided to put JGraLab into the Eclipse workspace since
Eclipse does not automatically scan its workspace for new projects.
JGRaLab's Ant build generates many source files. Each time you run
ant, you have
to refresh the project in Eclipse, so that the changes get reflected in the IDE.
You can download nightly builds from our
snapshots page. The
source jars contain the compiled class files and the source files. As such,
they are preferrable to the binary-only builds when you intend to develop
applications using JGraLab, because then you get nicer code completion, e.g.,
the real names of method parameters instead of just
You can find the API documentation for the current JGraLab master branch at our API Docs Page. This documentation is regenerated every night.
We've started writing a tutorial in the JGraLab Wiki. It's not yet complete, but we'll keep working on extending it.
