Class InstanceComparator<T>

java.lang.Object

org.dromara.hutool.core.comparator.InstanceComparator<T>

Type Parameters:

T - 用于比较的对象类型

All Implemented Interfaces:

Comparator<T>

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

按照指定类型顺序排序，对象顺序取决于对象对应的类在数组中的位置。

如果对比的两个对象类型相同，返回0，默认如果对象类型不在列表中，则排序在前

此类来自Spring，有所改造

5.4.1
