TYPO3.Flow

Currently (afaik), the only option to set a validator to a model property is to annotate it in the vicinity of the appropriate method property:

 1    /**
 2     * @FLOW3\Validate(type="NotEmpty")
 3     * @FLOW3\Validate(type="RegularExpression", options={ "regularExpression"="/^[mf]$/" })
 4     * @var string
 5     * @ORM\Column(length=1)
 6     */
 7    protected $gender;
 8
 9    /**
10     * @FLOW3\Validate(type="NotEmpty")
11     * @var \TYPO3\Party\Domain\Model\PersonName
12     * @ORM\OneToOne
13     */
14    protected $name;

I now have two additional options in mind, one would be via Configuration.yaml (or maybe even an additional Validation.yaml:

 1-
 2  property: \Acme\Northwind\Person.gender
 3  validators:
 4    - NotEmpty
 5    - RegularExpression
 6        options:
 7          regularExpression: /^[mf]$/
 8-
 9  property: \TYPO3\Party\Domain\Model\PersonName.firstName
10  validators:
11    - NotEmpty
12    - StringLength
13        options:
14          minimumLength: 2
15
16-
17  #dito for .lastName

Second would be to allow "deep" annotating via the parameter we already know from method argument annotation:

1    /**
2     * @FLOW3\Validate(type="NotEmpty")
3     * @FLOW3\Validate("$firstName", type="NotEmpty")
4     * @FLOW3\Validate("$lastName", type="NotEmpty")
5     * @var \TYPO3\Party\Domain\Model\PersonName
6     * @ORM\OneToOne
7     */
8    protected $name;

(for this example, remember \TYPO3\Party\Domain\Model\PersonName has properties firstName and lastName).
