How can we use Appium-adb?

Hi !
I found this Appium's adb wrapper :

but i don't know how can I use it. Currently when I want execute adb command I do something like this:

final Process exec = Runtime.getRuntime().exec("adb shell ls");

 final BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(exec.getInputStream()));

 String s;
 while((s = bufferedReader.readLine()) != null) {
     System.out.println(s);
 }

Are there any other way to execute adb commands from java client on appium ?
