Exemple:

• Basic usage, launch command and wait finish

String[] cmd = ... ;
ProcessBuilder processBuilder = new ProcessBuilder(cmd);

SimpleProcess sp = new SimpleProcessBuilder()
  .processBuilder(processBuilder)
  .outputRowListener(new OutChangeListener<>())
  .errorRowListener(new ErrChangeListener<>())
  .build();

sp.start();

• Output basic usage, launch command and get all output rows in one string

String[] cmd = ... ;
ProcessBuilder processBuilder = new ProcessBuilder(cmd);

StringAggregatorChangeListener aggregator = new StringAggregatorChangeListener();
SimpleProcess sp = new SimpleProcessBuilder()
  .processBuilder(processBuilder)
  .outputRowListener(aggregator)
  .errorRowListener(new ErrChangeListener<>())
  .build();

sp.start();

String output = aggregator.getValue();

• Input basic usage, launch command and send value to process

String[] cmd = ... ;
ProcessBuilder processBuilder = new ProcessBuilder(cmd);

ObservableValue<String> inputValue = new ObservableValue<>();
SimpleProcess sp = new SimpleProcessBuilder()
  .processBuilder(processBuilder)
  .inputValue(inputValue)
  .outputRowListener(new OutChangeListener<>())
  .errorRowListener(new ErrChangeListener<>())
  .build();

sp.startAsync();

TimeUnit.SECONDS.sleep(2);
inputValue.setValue("ping www.google.fr");  

while(true){
    TimeUnit.SECONDS.sleep(5);
    inputValue.setValue("exit");
    break;
}
