当Collection 接口没有对 Object.equals 的常规协定添加任何约定时,“直接”实现该 Collection 接口(换句话说,创建一个 Collection,但它不是 Set 或 List 的类)的程序员选择重写 Object.equals 方法时必须小心。 没必要这样做,最简单的方案是依靠 Object 的实现,然而实现者可能希望实现“值比较”,而不是默认的“...

The downside is that you have to refresh the init script manually with zgenom reset whenever you update your plugin list in your .zshrc. Zgenom can load oh-my-zsh-compatible and prezto-compatible plugins and themes, and will automagically git clone plugins for you when you add them to ...
