方法声明兼容,但PHP抱怨

所以我有这门课：

class JSObjectStorage extends \SplObjectStorage
{

    /**Adds a JavaScript object inside the storage,and optionally associate it to some data.*/    
    public function attach($javaScript,$data = null){}

    /**Removes the object from the storage.*/
    public function detach($javaScript){}

    /**Adds all objects-data pairs from a different JavaScriptBundle storage in the current storage.*/
    public function addAll(\SplObjectStorage $storage){}

    /**Removes objects contained in another storage from the current storage.*/
    public function removeAll(\SplObjectStorage $storage){}

    /**Removes all objects except for those contained in another storage from the current storage.*/
    public function removeAllExcept(\SplObjectStorage $storage){}

    /**Alias to JSObjectStorage::attach. */    
    public function offsetSet($javaScript,$data = null){}

    /**Alias to JSObjectStorage::detach*/
    public function offsetUnset($javaScript){}

    /**Returns the data associated with an object in the storage.*/
    public function offsetGet($javaScript){}

    /**This method calculates an identifier for the objects added to JSObjectStorage object.*/
    public function getHash($javaScript){}
}

这是SplObjectStorage：

http://php.net/manual/en/class.splobjectstorage.php

如您所见,它们是相同的,但是当我实例化JSObjectSTorage时,我收到以下错误：

Strict standards: Declaration of
MOWAFW\Core\Type\JavaScript\JSObjectStorage::addAll() should be
compatible with that of SplObjectStorage::addAll() in
/Users/**/JSObjectStorage.PHP on line 175

这恰好是removeAll()和removeAllExcept().

有任何想法吗？！

我正在使用：

PHP 5.3.10 with Suhosin-Patch (cli) (built: Feb 20 2012 22:55:53)

有人发布了一个名为 “Namespace interfaces not working due to type hinting issues” (Bug #40653)的错误报告,尽管PHP版本不同,它看起来像你的情况(它读取v.< 5.3.7).
