/**
 * Evaluates the predicate returning true if both predicates return true.
 * 
 * @param object  the input object
 * @return true if both decorated predicates return true
 */
public boolean evaluate(Object object) {
  return (iPredicate1.evaluate(object) && iPredicate2.evaluate(object));
}

/**
 * Evaluates the predicate returning the opposite to the stored predicate.
 * 
 * @param object  the input object
 * @return true if predicate returns false
 */
