# assertContainsOnly()
>[info] ## assertContainsOnly(string $type, Iterator|array $haystack[, boolean $isNativeType = NULL, string $message = ''])
当 `$haystack` 并非仅包含类型为 `$type` 的变量时报告错误,错误讯息由 `$message` 指定。
`$isNativeType` 是一个标志,用来表明 `$type` 是否是原生 PHP 类型。
`assertNotContainsOnly()` 是与之相反的断言,并接受相同的参数。
`assertAttributeContainsOnly()` 和 `assertAttributeNotContainsOnly()` 是便捷包装(convenience wrapper),以某个类或对象的 `public`、`protected` 或 `private` 属性为搜索范围。
