Seed

DummyGenerator generate random data. Which is fine, but sometimes (i.e.: in tests) you want it to generate same data each time. This is where seed() comes to the rescue.

Method seed() accepts param with a seed number. If you initialize generator with seed(1434) it will always return same name for ->firstName(), same address for ->buildingNumber(), same color for ->hexColor() and so on.

How can I use seed()

You have to change default randomizer to XoshiroRandomizer with desired seed number, i.e. for seed=123 it would be:

    // standard initialization, adapt this to your needs
    $container = \DummyGenerator\Container\DefinitionContainerBuilder::base();
    $generator = new \DummyGenerator\DummyGenerator($container);  
    // replace randomizer with XoshiroRandomizer, which supports seed
    $generator->addDefinition(
        \DummyGenerator\Definitions\Randomizer\RandomizerInterface::class,
        new \DummyGenerator\Core\Randomizer\XoshiroRandomizer(seed: 123)
    );
    // and from now on generator will use fixed seed to get data
