Why not add this code to a RAMDirectory constructor like:
public RAMDirectory(Directory d) throws IOException {
this();
final String[] ar = d.list();
for (int i = 0; i < ar.length; i++) {
// make place on ram disk
OutputStream os = createFile(ar[i]);
// read current file
InputStream is = d.openFile(ar[i]);
// and copy to ram disk
int len = (int) is.length();
byte[] buf = new byte[len];
is.readBytes(buf, 0, len);
os.writeBytes(buf, len);
// graceful cleanup
is.close();
os.close();
}
}
