Interface LWTResultListener

public interface LWTResultListener

Interface to define listener for LWT operations.
The "default void onSuccess(){}" method is called when LWT operation is successful. By default, it does nothing. Override it to implement your own behavior

The "void onError(LWTResult lwtResult)" method is called if LWT operation fails for some reasons. The failure details can be extracted from the LWTResultListener.LWTResult class

Below is an example of usage for LWT result listener

 LWTResultListener lwtListener = new LWTResultListener() {

 public void onError(LWTResult lwtResult) {

 //Get type of LWT operation that fails
 LWTResult.Operation operation = lwtResult.operation();

 // Print out current values
 TypedMap currentValues = lwtResult.currentValues();
 currentValues
 .entrySet()
 .forEach(entry -> System.out.println(String.format("%s = %s",entry.getKey(), entry.getValue())));
 }
 };

 .update()
 .fromBaseTable()
 .firstname_Set("new firstname")
 .where()
 .login_Eq("jdoe")

 .withLwtResultListener(lwtListener)
