How to add Saripaar Validator to code, and not as an attribute?

Question

As explained on the official GitHub page, adding validators via attributes is easy:

@NotEmpty
@Email
private EditText email;

Now that the EditText has been verified that it is not empty and that it contains email. But now, how can I add these two identical conditions from the code? Looking through the code, there seems to be this method:

public <VIEW extends View> void put(final VIEW view, final QuickRule<VIEW>... quickRules)

And I tried using it like:

mValidator.put(txtDestinationAddr, new NotEmptyRule(), new EmailRule());

But it seems that the constructors for all the rules are protected and cannot be used in this way.
