README
Generates a NullObject from an interface. It was created for testing and AOP.
Installation
composer require --dev koriym/null-object
Getting Started
Instantiate a Null Object from an Interface.
interface FooInterface { public function do(): void; }
$nullObject = $this->nullObject->newInstance(FooInterface::class); assert($nullObject instanceof FooInterface); $nullObject->do(); // nothing's going to happen
newInstance()
defines a class with eval
, but use save()
to save the generated code to a file.
$class = $this->nullObject->save(FooInterface::class, '/path/to/saveDirectory'); assert(new $class instanceof FooInterface);
On the fly
It is also possible to create a null object by simply adding a Null
suffix to the interface by registering autoloader, If this doesn't sound too wild to you.
$loader = require __DIR__ . '/vendor/koriym/null-object/autoload.php'; spl_autoload_register($loader);
or add it to autoload-dev
in composer.json.
"autoload-dev": { "files": ["./vendor/koriym/null-object/autoload.php"] }
You can create Null Object as follows.
$nullClass = FooInterface::class . 'Null'; // add Null suffix to the interface $foo = new $nullClass; // instantiate a NullObject assert($foo instanceof FooInterface);
Note
Inherited interfaces are not yet supported.
