BridJ: ultimate native interoperability library for Java (call C, C++, Objective-C, C# with style and performance).

Don't panic ! While there are indeed many classes in BridJ, the only ones you need to know about are :

{@link org.bridj.Pointer} : your vital friend in this native mess
{@link org.bridj.BridJ} : to tune the native libraries resolution process, amongst other things
All the classes generated by JNAerator : they will look like your original C / C++ code anyway.

See BridJ's Wiki for more information.
