说明
abstract
public
Ds\Hashable::equals (
object
$obj
) :
bool
Determines whether another object is equal to the current instance.
This method allows objects to be used as keys in structures such as Ds\Map and Ds\Set, or any other lookup structure that honors this interface.
Note:
It's guaranteed that
obj
is an instance of the same class.
Caution
It's important that objects which are equal also have the same hash value. See Ds\Hashable::hash().
参数
-
obj
-
The object to compare the current instance to, which is always an instance of the same class.

if equal, FALSE
otherwise.
