Every individual also will have a " words " array reference that will hold all the words the individual made during this generation 每一个个体还拥有一个“单词”数组引用，在这个数组中保持有在衍生过程中那个个体生成的单词。
Method of appconfig can be used to get the value of an individual parameter ; because the parameters of interest are always array references , i automatically de - reference them 方法可以用来得到各个参数的值；由于感兴趣的参数总是数组引用，我自动地对它们进行解引用。
By simply copying the array reference instead of cloning it , both the message and the class that produces it hold a reference to the master copy of the previous bids array 通过简单地复制而不是克隆数组引用，消息和产生消息的类都保存了前一投标数组的主副本的一个引用。
You can do it by accessing internal appconfig : : state data or the array reference returned to you as the value of the array variable , but it is not recommended that you do so 可以通过访问内部的appconfig : : state数据或作为数组变量值返回给您的数组引用来实现这一步，但我们建议您不要这样做。
Note that if array references or other mutable fields are being initialized from arguments passed to a constructor , you must defensively copy the caller - provided arguments or else you can t be sure that you have exclusive access to the array 注：如果从传递给构造函数的参数中初始化数组引用或其它可变字段，您必须用防范措施将调用程序提供的参数或您无法确保具有独占访问权的其它信息复制到数组。
There may be a cost to making defensive copies when passing an array reference to another class , but unless you are sure that the other class either makes its own copy or that it will not hold the reference for longer than the duration of the call , you probably want to make a copy before passing the array 当传递一个数组引用到另一个类时，可能有创建防御副本的代价，除非您能确保其他类要么创建了它自己的副本，要么只在调用期间保存引用，否则您可能需要在传递数组之前创建副本。
