public abstract @interface InverseMethod
implements Annotation

The InverseMethod annotation may be applied to any method used in two-way data binding to declare the method used to invert the call when going from the View's attribute value to the bound data value.

The final parameter of this method must match the return value of its inverse and the return value of this method must match the final parameter of the its inverse.

 @InverseMethod("convertIntToString")
 public static int convertStringToInt(String value) {
     try {
         return Integer.parseInt(value);
     } catch (NumberFormatException e) {
         return -1;
     }
 }

 public static String convertIntToString(int value) {
     return String.valueOf(value);
 }
