}
} else {

}示例2: seek
/**
* Seeks to a position.

* @return void
* @throws \InvalidArgumentException when $position is not an integer.
* @throws \OutOfBoundsException when the seek $position exeeds the traversable's length.

* in each of the actions and creating them in the database associating
* them with actions.

* @param string $methodName The original method name to parse.
* @return mixed Either an array of error or false.
