* Performs access check for this user.

* with the tasks and roles assigned to the user.
* Since version 1.1.11 a param with name 'userId' is added to this array, which holds the value of
* {@link getId()} when {@link CDbAuthManager} or {@link CPhpAuthManager} is used.
* @param boolean $allowCaching whether to allow caching the result of access check.
* When this parameter
* is true (default), if the access check of an operation was performed before,
* its result will be directly returned when calling this method to check the same operation.
* If this parameter is false, this method will always call {@link CAuthManager::checkAccess}
* to obtain the up-to-date access result. Note that this caching is effective
* only within the same request and only works when <code>$params=array()</code>.
* @return boolean whether the operations can be performed by this user.
