br.com.caelum.vraptor.validator.Validations

public class Validations
extends Object

Hamcrest based validation support. Uses: validator.checking(new Validations() {{ if (that(user, is(notNullValue())) { // that will return if the match was successful that(user.getAge() > 17, "user.age", "user.is.underage"); // boolean assertions that(user.getRoles(), hasItem("ADMIN"), "user.roles", "user.is.not.admin"); // hamcrest assertions } }}); You can use any hamcrest Matcher. Some helpful matchers can be found on org.hamcrest.Matchers.
