laasti / lazydata example snippets

$data = [
    'title' => 'render_title',

    'with_class' => ['=my_class', 'my_function'], //or '=my_class::my_function',

    'meta' => function() {
        return [
            'description' => 'My description'
        ]
    }
];

$viewdata = new Laasti\Lazydata\Data($data);
$viewdata->set('username', function() {return 'George';});

//You can use dot notation within the lazy loaded data
$viewdata->get('meta.description'); //Returns 'My description'

    $data = [
        'native_example' => 'strtoupper:test', //I know, it's a stupid example :P

    $resolver->setFilter('closure', function($value) {
        return md5($value.'MYSALT');
    });
    $viewdata = new Laasti\Lazydata\Data($data, $resolver);

    $viewdata->get('native_example'); //Returns 'TEST'
    $viewdata->get('closure_example'); //Returns '56e29f03228697ad59822c71eb4d7750'

//We need to setup the ContainerResolver that comes with the package

$container->add('container_key', 'some value');

$viewdata->set('viewdata_key', '=container_key');
$viewdata->get('viewdata_key'); //Returns 'some value'

//Returns the value from SomeClass->myMethod();, SomeClass is resolved with the container
