DEVatNumberFormatValidatorsConfig description

A configuration class that provides a match for the vat number format validators for the country Germany.

Class interface:

getCountry - returns Germany Country instance;
getValidators - returns validators tuple

When initializing the default configuration, the getValidators function returns a tuple with a single validator - an instance of DEVatFormatValidator.

$config = new DEVatNumberFormatValidatorsConfig();

$config->getCountry();      // returns Germany Country instance
$config->getValidators();   // returns CountryVatFormatValidators with one item - instance of DEVatFormatValidator

You can override the default validator by initializing the configuration class object with a new default validator through the first parameter of the class constructor. Attention - validator must implement interface CountryVatFormatValidatorInterface.

$newDefaultValidator = new NewDefaultValidator();                       // instance of CountryVatFormatValidatorInterface
$config = new DEVatNumberFormatValidatorsConfig($newDefaultValidator);  // initialize with new default validator

$config->getValidators();   // returns CountryVatFormatValidators with one item - $newDefaultValidator

You can add additional validators to the default validator via the second constructor parameter.

Attention - additional validators parameter must be instance of tuple CountryVatFormatValidators. And each additional validator must implement interface CountryVatFormatValidatorInterface.

$firstAdditionalValidator = new FirstAdditionalValidator();   // instance of CountryVatFormatValidatorInterface
$secondAdditionalValidator = new SecondAdditionalValidator(); // instance of CountryVatFormatValidatorInterface

$config = new DEVatNumberFormatValidatorsConfig(
    null,
    (
        new CountryVatFormatValidators(
            $firstAdditionalValidator,
            $secondAdditionalValidator
        )
    )
);

// returns CountryVatFormatValidators with three items:
// default preconfigured validator by default - instance of DEVatFormatValidator
// $firstAdditionalValidator - from additional tuple
// $secondAdditionalValidator - from additional tuple
$config->getValidators();

You can also completely rebuild the configuration by passing the default validator and a tuple of additional validators to the config class constructor.

$defaultValidator = new DefaultValidator();                   // instance of CountryVatFormatValidatorInterface
$firstAdditionalValidator = new FirstAdditionalValidator();   // instance of CountryVatFormatValidatorInterface
$secondAdditionalValidator = new SecondAdditionalValidator(); // instance of CountryVatFormatValidatorInterface

$config = new DEVatNumberFormatValidatorsConfig(
    $defaultValidator,
    (
        new CountryVatFormatValidators(
            $firstAdditionalValidator,
            $secondAdditionalValidator
        )
    )
);

// returns CountryVatFormatValidators with three items:
// $defaultValidator from constructor first parameter
// $firstAdditionalValidator - from additional tuple
// $secondAdditionalValidator - from additional tuple
$config->getValidators();

More use case examples can be found in the package's unit tests.
