Codacy Badge Build Status License Release Maven Central

Copyright (C) 2012-2017, TomTom International BV. All rights reserved.

SpeedTools is a collection of generic utilities, originally developed by Rijn Buve, Ruud Diterwich, Daan van Dijk and Andreas Wuest for a large commercial project.

The library was created to develop highly scalable web services, using Typesafe Akka, Google Guice and MongoDB, but many of the tools are usable in other contexts as well.

For documentation on what this library offers, have a look at the speedtools/src/site/markdown directory, which is the entry point for the site documentation. It contains a list of all modules and APIs.

You can view the general documentation here:

Or have a look at the JavaDoc API documentation at:

The versioning scheme of the library starts at 3.0.0, because earlier releases exist were disclosed within TomTom only. From version 3.0.0 TomTom decided to contribute this library under the Apache License 2.0 to the open source community.

The test coverage of the project is unevenly distributed. Some of the modules have excellent test coverage in units tests, others lag a bit behind, or cannot be run without running, for example, a local MongoDB instance, or having access to secret API keys. Such unit tests have been marked as @Ignore in the source tree, which brings the test coverage down. We welcome initiatives to increase the test coverage further. Most of the original code was suspect to strict code reviews.

There is an additional project speedtools-examples with real-life examples of how to use the SpeedTools library. Check it out at

Happy coding!

Using Git and .gitignore

It's good practice to set up a personal global .gitignore file on your machine which filters a number of files on your file systems that you do not wish to submit to the Git repository. You can set up your own global ~/.gitignore file by executing: git config --global core.excludesfile ~/.gitignore

In general, add the following file types to ~/.gitignore (each entry should be on a separate line): *.com *.class *.dll *.exe *.o *.so *.log *.sql *.sqlite *.tlog *.epoch *.swp *.hprof *.hprof.index *.releaseBackup *~

If you're using a Mac, filter: .DS_Store* Thumbs.db

If you're using IntelliJ IDEA, filter: *.iml *.iws .idea/

If you're using Eclips, filter: .classpath .project .settings .cache

If you're using NetBeans, filter: nb-configuration.xml *.orig

The local .gitignore file in the Git repository itself to reflect those file only that are produced by executing regular compile, build or release commands, such as: target/ out/
