The Directory
class is probably the first instance of what we now call an “opaque object”.
Opaque objects are normally the result of converting resources to objects,
which in general implies, being final
, being not serializable,
not constructible via new
, cannot be cast, and to not implement any methods.
However, as this class has existed since PHP 4 none of these things are formally implemented.
Valid instances of this class are created by calling the dir()
function.
But one can create a broken instance by just using new Directory()
,
which is visible if one tries to call one of its methods.
As it seems likely that we will repurpose this class when converting directory resources to objects; we think it makes sense to already convert this class to behave like an opaque object.
We propose to make the following changes to the Directory
class:
final
