/**

 * relayed to the caller of the composed operation. This method is just convenience, to provide the ability to
 * transform this primitive function to an operation returning {@code double}.
 *
 * @param after The operator to apply after this function is applied
 * @return A composed {@code BiObjBooleanToDoubleFunction} that first applies this function to its input, and then
 * applies the {@code after} operator to the result.
 * @throws NullPointerException If given argument is {@code null}
