Ds\Hashable::equals

(PECL ds >= 1.0.0)

Ds\Hashable::equals — Determines whether an object is equal to the current instance

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.

返回值

TRUE if equal, FALSE otherwise.
