Since 2012 our team has hosted a copy of the wpilib javadocs on our website.
I’ve updated the hosted javadocs for the 2015 season.
They can be viewed at http://team2168.org/javadoc/
You might be wondering why we bother, because this version of the javadocs includes source links. You can click a link within the javadocs and it will bring you to an html version of the source code for the class in question.
Personally I find this very helpful when the comments in the javadoc don’t quite answer a question I have about how a particular class/method works.
If you’re interested in making your own version of the javadocs with linked sources, the command is as follows:
<path_to_jdk>\bin\javadoc.exe -d <output_directory> -sourcepath <path_to_wpilib>\java\current\lib\src\ -subpackages com:edu -linksource
