Hi Ben,
The Validator can contain any number of validations or just one for a single
attribute.
To declare separate validators for each router route, you could attach the
validators to the router and then the target resource class to each
corresponding validator:
router.attach("pathA", validatorA);
router.attach("pathB", validatorB);
router.attach("pathC", validatorC);
validatorA.setNext(MyServerResourceA.class);
validatorB.setNext(MyServerResourceA.class);
validatorC.setNext(MyServerResourceA.class);
For your second example, you can't reuse the same Validator instance as the
target resource is different for each one. However, you could create a
Validator subclass facilitating the configuration and reuse of your attributes'
format.
Best regards,
Jerome Louvel

Objet : Re: Examples of org.restlet.routing.Validator?
Ah, very good, that protected method was confusing me since it made it
look like I was supposed to extend.
As a Filter, is it intended to hold a mapping of all validations for
all routes or does it wrap each individual validated route? I'm not
sure how to go from the basic
router.attach("pathA", MyServerResourceA.class);
router.attach("pathB", MyServerResourceB.class);
router.attach("pathC", MyServerResourceC.class);
to something that wraps MyServerResource in a Validator which is
different for each resource. Perhaps some quick pseudo code?
Additionally, what about a structure like:
router.attach("pathA/{ida}", MyServerResourceA.class);
router.attach("pathA/{ida}/pathB/{idb}", MyServerResourceB.class);
router.attach("pathA/{ida}/pathB/{idb}/pathC/{idc}", MyServerResourceC.class);
Is there a way to reuse the validator of {ida} in the two following routes?
