“实现包装方法”是什么意思？ [英] What is meant by "implement a wrapper method"?

问题描述

我已经获得了一个编程任务，我要做的一件事就是实现方法，它是一个包装器方法，它依赖于另一种方法来从最低到最高对坐标进行排序。我不确定实现包装器方法的确切含义。

I have been given a programming assignment and one of the things I have to do is implement method which a wrapper method which relies on another method to sort the coordinates from lowest to highest. I am unsure on what exactly is meant by implementing a wrapper method.

static void sortCoordsByZ(double[][] coords) {
    //implement the wrapper method for the recursive sort method. all work is done the recursive sort method
}

static void recursiveSort(double[][] coords, int lo, int hi) {
    //recursive sort method
}

推荐答案

包装方法是适配器或外观;它为现有方法提供了另一种接口。

A wrapper method is an adapter or a façade; it provides an alternative interface for an existing method.

您被要求编写外观（外观） - 为不需要的客户提供更简单的界面指定高值和低值。

You've been asked to write a façade (facade) - to provide a simpler interface for clients that don't need to specify high and low values.
