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

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:
Code:
<path_to_jdk>\bin\javadoc.exe -d <output_directory> -sourcepath <path_to_wpilib>\java\current\lib\src\ -subpackages com:edu -linksource
Past versions of the javadocs are available if required:
