ReflectionClass::resetAsLazyGhost — Resets an object and marks it as lazy
说明
$object, callable $initializer, int $options = 0): void
Resets an existing object and marks it as lazy.
The object's destructor is called (if one exists) unless the
ReflectionClass::SKIP_DESTRUCTOR flag is specified. In
the special case where the object is an initialized proxy, the real instance
is detached from the proxy. If the real instance is no longer referenced
elsewhere, its destructor is called regardless of the
SKIP_DESTRUCTOR flag.
Dynamic properties are removed, and the value of properties declared on the
class is discarded as though unset() was called, and
marked as lazy. This implies that if the object is an instance of a subclass
with additional properties, these properties are not modified and not made
lazy.
Readonly
properties are also not modified and not made lazy if they are
final or the class itself is final.
If no properties were marked lazy, the object is not marked as lazy. See also Lazy Objects Lifecycle.
Otherwise, after calling this method, the behavior of the object is the same as an object created by ReflectionClass::newLazyGhost() (except for subclass and readonly properties, as described above).
The object is not replaced by another one, and its identity remains
unchanged. Functionality such as spl_object_id(),
spl_object_hash(),
SplObjectStorage, WeakMap,
WeakReference, or
the identity operator
(===) are unaffected.
参数
object- A non-lazy object, or an initialized lazy object.
initializer- An initializer callback with the same signature and purpose as in ReflectionClass::newLazyGhost().
options-
optionscan be a combination of the following flags:-
ReflectionClass::SKIP_INITIALIZATION_ON_SERIALIZE - By default, serializing a lazy object triggers its initialization. Setting this flag prevents initialization, allowing lazy objects to be serialized without being initialized.
-
ReflectionClass::SKIP_DESTRUCTOR - By default, the object destructor is called (if any) before making it lazy. This provides safety regarding any preexisting state in the object. This flag disables that behavior, allowing objects to be reset as lazy without calling the destructor.
-
返回值
没有返回值。
错误／异常
A ReflectionException if the object is lazy and non-initialized.
An Error if the object is being initialized, or if the
object properties are being iterated with
foreach.
