        login.getValidation().add(new StringLength({min: 3}))
        let password = new Input('password')
        password.getValidation().add(new StringLength({min: 3}))

        this.add(login).add(password)
    }
}

var validator = new LoginFilter
//Invalid data
validator.setData({login: 'aa', password: 'dd'})
validator.isValid().then(
    function() {
        console.log('valid')
    },
    function(messages) {
        console.log(messages)
    }
)
//Valid data

            new Callback((value) => {
                if (value === '***') {
                    return Promise.reject('value cannot be ***')
                }
            })
        ]
