// ['lastname' =\u003e 'Moelleken']\n$arrayy-\u003eget('Lars.lastname'); // 'Moelleken'\n```\n\n### Access via \"array\"-syntax:\n\n```php\n$arrayy = new A(['Lars' =\u003e ['lastname' =\u003e 'Moelleken']]);\n\n$arrayy['Lars']; // ['lastname' =\u003e 'Moelleken']\n$arrayy['Lars']['lastname']; // 'Moelleken'\n```\n\n### Access via \"object\"-syntax:\n\n```php\n$arrayy = new A(['Lars' =\u003e ['lastname' =\u003e 'Moelleken']]);\n\n$arrayy-\u003eLars; // Arrayy['lastname' =\u003e 'Moelleken']\n$arrayy-\u003eLars-\u003elastname; // 'Moelleken'\n```\n\n### Set values via \"Arrayy\"-syntax: (dot-notation)\n\n```php\n$arrayy = new A(['Lars' =\u003e ['lastname' =\u003e 'Mueller']]);\n\n$arrayy-\u003eset('Lars.lastname', 'Moelleken');\n$arrayy-\u003eget('Lars.lastname');

// 'M眉ller'\n```\n\n## PhpDoc @property checking\n\nThe library offers a type checking for @property phpdoc-class-comments, as seen below:\n\n```php\n/**\n * @property int $id\n * @property int|string $firstName\n * @property string $lastName\n * @property null|City $city\n *\n * @extends \\Arrayy\\Arrayy\u003carray-key,mixed\u003e\n */\nclass User extends \\Arrayy\\Arrayy\n{\n protected $checkPropertyTypes = true;\n\n protected $checkPropertiesMismatchInConstructor = true;\n}\n\n/**\n * @property string|null $plz\n * @property string $name\n * @property string[] $infos\n *\n * @extends \\Arrayy\\Arrayy\u003carray-key,mixed\u003e\n */\nclass City extends \\Arrayy\\Arrayy\n{\n protected $checkPropertyTypes = true;\n\n protected $checkPropertiesMismatchInConstructor = true;\n}\n\n$cityMeta = City::meta();\n$city = new City(\n [\n $cityMeta-\u003eplz =\u003e null,\n $cityMeta-\u003ename =\u003e 'D眉sseldorf',\n $cityMeta-\u003einfos =\u003e ['lall'],\n ]\n);\n\n$userMeta = User::meta();\n$user = new User(\n [\n $userMeta-\u003eid =\u003e 1,\n $userMeta-\u003efirstName =\u003e 'Lars',\n $userMeta-\u003elastName =\u003e 'Moelleken',\n $userMeta-\u003ecity =\u003e $city,\n ]\n);\n\nvar_dump($user['lastName']); // 'Moelleken'\nvar_dump($user[$userMeta-\u003elastName]); // 'Moelleken'\nvar_dump($user-\u003elastName); // Moelleken\n\nvar_dump($user['city.name']); // 'D眉sseldorf'\nvar_dump($user[$userMeta-\u003ecity][$cityMeta-\u003ename]); // 'D眉sseldorf'\nvar_dump($user-\u003ecity-\u003ename); // D眉sseldorf\n```\n\n- \"checkPropertyTypes\": activate the type checking for all defined @property in the class-phpdoc\n- \"checkPropertiesMismatchInConstructor\": activate the property mismatch check, so you can only add an \n array with all needed properties (or an empty array) into the constructor\n\n## OO and Chaining\n\nThe library also offers OO method chaining, as seen below:\n\nsimple example:\n```php\necho a(['f貌么', 'b脿艡', 'b脿艡'])-\u003eunique()-\u003ereverse()-\u003eimplode(','); // 'b脿艡,f貌么'\n```\n\ncomplex example:\n```php\n/**\n * @property int $id\n * @property string $firstName\n * @property string $lastName\n *\n * @extends \\Arrayy\\Arrayy\u003carray-key,mixed\u003e\n */\nclass User extends \\Arrayy\\Arrayy\n{\n protected $checkPropertyTypes = true;\n\n protected $checkPropertiesMismatchInConstructor = true;\n}\n\n/**\n * @template TKey of array-key\n * @extends AbstractCollection\u003cTKey,User\u003e\n */\nclass UserCollection extends \\Arrayy\\Collection\\AbstractCollection\n{\n /**\n * The type (FQCN) associated with this collection.\n *\n * @return string\n */\n public function getType()\n {\n return User::class;\n }\n}\n\n\n$m = User::meta();\n\n$data = static function () use ($m) {\n yield new User([$m-\u003eid =\u003e 40, $m-\u003efirstName =\u003e 'Foo', $m-\u003elastName =\u003e 'Moelleken']);\n yield new User([$m-\u003eid =\u003e 30, $m-\u003efirstName =\u003e 'Sven', $m-\u003elastName =\u003e 'Moelleken']);\n yield new User([$m-\u003eid =\u003e 20, $m-\u003efirstName =\u003e 'Lars', $m-\u003elastName =\u003e 'Moelleken']);\n yield new User([$m-\u003eid =\u003e 10, $m-\u003efirstName =\u003e 'Lea', $m-\u003elastName =\u003e 'Moelleken']);\n};\n\n$users = UserCollection::createFromGeneratorFunction($data);\n$names = $users\n -\u003efilter(static function (User $user): bool {\n return $user-\u003eid \u003c= 30;\n })\n -\u003ecustomSortValuesImmutable(static function (User $a, User $b): int {\n return $a-\u003efirstName \u003c=\u003e $b-\u003efirstName;\n })\n -\u003emap(static function (User $user): string {\n return $user-\u003efirstName;\n })\n -\u003eimplode(';');\n\nstatic::assertSame('Lars;Lea;Sven', $names);\n```\n\n## Implemented Interfaces\n\n`Arrayy\\Arrayy` implements the `IteratorAggregate` interface, meaning that\n`foreach` can be used with an instance of the class:\n\n``` php\n$arrayy = a(['f貌么b脿艡', 'foo']);\nforeach ($arrayy as $value) {\n echo $value;\n}\n// 'f貌么b脿艡'\n// 'foo'\n```\n\nIt implements the `Countable` interface, enabling the use of `count()` to\nretrieve the number of elements in the array:\n\n``` php\n$arrayy = a(['f貌么', 'foo']);\ncount($arrayy); // 2\n```\n\n## PHP 5.6 Creation\n\nAs of PHP 5.6, [`use function`](https://wiki.php.net/rfc/use_function) is\navailable for importing functions. Arrayy exposes a namespaced function,\n`Arrayy\\create`, which emits the same behaviour as `Arrayy\\Arrayy::create()`.\nIf running PHP 5.6, or another runtime that supports the `use function` syntax,\nyou can take advantage of an even simpler API as seen below:\n\n``` php\nuse function Arrayy\\create as a;\n\n// Instead of: A::create(['f貌么', 'b脿艡'])-\u003ereverse()-\u003eimplode();\na(['f貌么', 'b脿艡'])-\u003ereverse()-\u003eimplode(','); // 'b脿艡,f貌么'\n```\n\n## Collections\n\nIf you need to group objects together, it's not a good idea \nto use a simple array or Arrayy object. For these cases you can use the ```AbstractCollection```\nclass.\n\nIt will throw a ```InvalidArgumentException``` if you try to add a non valid object into the collection.\n\ne.g.: \"YOURCollection.php\" (see example ```/tests/CollectionTest.php``` on github)\n```php\nuse Arrayy\\Collection\\AbstractCollection;\n\n/**\n * @extends AbstractCollection\u003carray-key,YOURInterface\u003e\n */\nclass YOURCollection extends AbstractCollection\n{\n /**\n * The type (FQCN) associated with this collection.\n *\n * @return string\n */\n public function getType(): string\n {\n return YOURInterface::class;\n }\n}\n\n$YOURobject1 = new YOURClass();\n$YOURobject2 = new YOURClass();\n\n$YOURcollection = new YOURCollection($YOURobject1);\n$YOURcollection-\u003eadd($YOURobject2); // add one more object\n\n// Or, you can use an array of objects.\n//\n// $YOURcollection = new YOURCollection([$YOURobject1, $YOURobject2]);\n\n// Or, if you don't want to create new classes ... \n// ... and you don't need typehints and autocompletion via classes.\n//\n// $YOURcollection = \\Arrayy\\Collection::construct(YOURInterface::class, [$YOURobject1]);\n// $YOURcollection-\u003eadd($YOURobject2); // add one more object\n\n// Or, if you don't like classes at all. ;-)\n//\n// $YOURcollection = \\Arrayy\\collection(YOURInterface::class, [$YOURobject1]);\n// $YOURcollection-\u003eadd($YOURobject2); // add one more object\n\nforeach ($YOURcollection as $YOURobject) {\n if ($YOURobject instanceof YOURInterface) {\n // Do something with $YOURobject\n }\n}\n``` \n\nYou can also use \"dot-notation\" to get data from your collections e.g.\n```$YOURcollection-\u003eget('3123.foo.bar');```\n\n## Pre-Defined Typified Collections\n\n### simple example\n\nThis will throw a \"TypeError\"-Exception. \n\n```php\nuse Arrayy\\Type\\StringCollection;\n\n$collection = new StringCollection(['A', 'B', 'C', 1]);\n```\n\n### complex example\n\nThis will NOT throw a \"TypeError\"-Exception. \n\n```php\nuse Arrayy\\Type\\IntCollection;\nuse Arrayy\\Type\\StringCollection;\nuse Arrayy\\Type\\InstancesCollection;\nuse Arrayy\\Type\\TypeInterface;\n\n$collection = InstancesCollection::construct(\n TypeInterface::class,\n [new StringCollection(['A', 'B', 'C']), new IntCollection([1])]\n);\n\n$collection-\u003etoArray(true); // [['A', 'B', 'C'], [1]]\n```\n\n## Convert JSON-Data into Objects (Collection)\n\n```php\n\nnamespace Arrayy\\tests\\Collection;\n\nuse Arrayy\\Collection\\AbstractCollection;\n\n/**\n * @extends AbstractCollection\u003carray-key,\\Arrayy\\tests\\UserData\u003e\n */\nclass UserDataCollection extends AbstractCollection\n{\n /**\n * The type (FQCN) associated with this collection.\n *\n * @return string\n */\n public function getType()\n {\n return \\Arrayy\\tests\\UserData::class;\n }\n}\n\n$json = '[{\"id\":1,\"firstName\":\"Lars\",\"lastName\":\"Moelleken\",\"city\":{\"name\":\"D眉sseldorf\",\"plz\":null,\"infos\":[\"lall\"]}}, {\"id\":1,\"firstName\":\"Sven\",\"lastName\":\"Moelleken\",\"city\":{\"name\":\"K枚ln\",\"plz\":null,\"infos\":[\"foo\"]}}]';\n$userDataCollection = UserDataCollection::createFromJsonMapper($json);\n\n/** @var \\Arrayy\\tests\\UserData[] $userDatas */\n$userDataCollection-\u003egetAll();\n\n$userData0 = $userDataCollection[0];\necho $userData0-\u003efirstName; // 'Lars'\n$userData0-\u003ecity; // CityData::class\necho $userData0-\u003ecity-\u003ename; // 'D眉sseldorf'\n\n$userData1 = $userDataCollection[1];\necho $userData1-\u003efirstName; // 'Sven'\n$userData1-\u003ecity;
