Class IndexedComparator<T>

java.lang.Object

cn.hutool.core.comparator.IndexedComparator<T>

Type Parameters:

T - 被排序元素类型

All Implemented Interfaces:

Comparator<T>

public class IndexedComparator<T>
extends Object
implements Comparator<T>

按照数组的顺序正序排列，数组的元素位置决定了对象的排序先后
默认的，如果参与排序的元素并不在数组中，则排序在前（可以通过atEndIfMiss设置)

Since:

4.1.5
