There is this rule already that narrows union return types.
There is also this case of return type that can be narrowed
abstract class AbstractFactory
abstract protected function build() : object;
class AppleFactory extends AbstractFactory
#[Override]
protected function build(): object
{
return new Apple();
}
In the example above the return type of method build in AppleFactory can be narrowed down to Apple.
class AppleFactory extends AbstractFactory
#[Override]
protected function build(): Apple
{
return new Apple();
}
One approach is to check whether the method has the override attribute to make the rule less aggressive
But alternatively the rule can check any method that has a return type object and check what is actually returned, and replace the return type.
Would you consider adding such a rule if i make a pr ? If yes, which version ? the one that checks if the method has the Override attribute ? or the more generic
