<p>This class is the native implementation of class <a class="el" href="classorg_1_1openisis_1_1Db.html">Db</a>. </p>
<h3>Installation</h3>
<p>The shared library "openjsis" must be loadable. On a UNIX System, make sure that the file libopenjsis.so resides in a directory listed by the environment variable LD_LIBRARY_PATH or in /etc/ld.so.conf. If you just drop it in /usr/lib or similar dir, you may have to run a command like ldconfig. </p>
<p>On Windows, put openjsis.dll somewhere in the PATH. </p>
