Usage

Migration

Migration entity system allows to design data structure for migration, to manage, retrieve and save its data in persistence.

Elements

• MigEntity

  Extends save configured entity features. Allows to design a migration entity, to save it.

• MigEntityCollection

  Extends fixed entity collection features. Allows to design collection of migration entities.

• MigEntityFactory

  Extends fixed entity factory features. Allows to design migration entity factory, to provide migration entity objects.

• MigEntityRepository

  Extends fixed multi repository features. Allows to design migration entity repository, to save data, from migration entity, in persistence.

• MigEntityCollectionRepository

  Extends fixed multi collection repository features. Allows to design migration entity collection repository, to save data, from migration entity collection, in persistence.

• SqlMigEntity

  Extends migration entity features. Uses SQL rules for attributes validation.

• SqlMigEntityFactory

  Extends migration entity factory features. Provides SQL migration entity objects.

• SqlMigEntityRepository

  Extends migration entity repository features. Uses SQL table persistor, as persistence.

• SqlMigEntityCollectionRepository

  Extends migration entity collection repository features. Uses SQL table persistor, as persistence.

// Get migration entity factory
use liberty_code\migration\entity\model\MigEntityFactory;
$migEntityFactory = new MigEntityFactory($provider);
...
// Get new migration entity
$migEntity = $migEntityFactory->getObjEntity();
...

Builder

Builder allows to hydrate existing migration with migration entity collections and vice versa.

// Get migration entity collection
use liberty_code\migration\entity\model\MigEntityCollection;
$migEntityCollection = new MigEntityCollection();
...
// Get migration entity builder
use liberty_code\migration\entity\build\model\DefaultBuilder;
$migEntityBuilder = new DefaultBuilder($migEntityFactory);
...
// Hydrate migration entity collection
$migEntityBuilder->hydrateMigEntityCollection(
    $migEntityCollection, 
    $migrationCollection
);
...
foreach($migEntityCollection->getTabKey() as $key) {
    echo($migEntityCollection->getItem($key)->strAttrKey .'<br />');
}
/**
 * Show: 
 * Migration key 1
 * ...
 * Migration key N
 */
