Ds\Hashable::equalsDetermines whether an object is equal to the current instance

说明

abstract public Ds\Hashable::equals(object $obj): bool

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.

注意:

It's guaranteed that obj is an instance of the same class.

警告

It's important that objects which are equal also have the same hash value. See Ds\Hashable::hash().
