Package de.intarsys.nativec.jna

Class JnaNativeInterface

java.lang.Object

de.intarsys.nativec.jna.JnaNativeInterface

All Implemented Interfaces:

INativeInterface

public class JnaNativeInterface
extends java.lang.Object
implements INativeInterface

An INativeInterface implemented using JNA, a LGPL licensed Java native interface abstraction.

In our point of view, JNA has the power of deploying all what we wanted to have, but is ill designed in some key hot spots - so we worked around and built on top of our own interfaces.
